RESPONSE ONE:
Research
The Cerebrum consists of the frontal lobe, parietal lobe, occipital lobe, temporal lobe and the insula. All five of these lobes have their own set of unique functions. Today, I will be going in depth about the frontal lobe, which is located directly behind the frontal bone, and superior to the eyes. According to the Cleveland Clinic, the frontal lobe takes up between 25% and 40% of the brain’s cerebral cortex and is composed of neurons and glial cells. The frontal lobe is responsible for our conscious, abstract thought; explicit or declarative memory; cognitive and emotional processes such as mood, motivation, foresight, planning, decision making, emotional control, and judging socially appropriate behavior; and in speech production (Saladin, 2024). Anything a person does that involves thinking or a conscious action, relies heavily on the frontal lobe.
The frontal lobe can be divided into two main areas: the motor cortex and the prefrontal cortex. The main function of the motor cortex is to control voluntary movement like writing, expressive language and ocular movement. Located in the front part of the frontal lobe is the prefrontal cortex, it is considered the ultimate expression of human brain development, and acts as a mediator between cognition and feelings through executive functions (CogniFit & Cognifit, 2024).
Critical Thinking
The frontal lobe is the slowest part of the brain to mature, continuing to develop until a person reaches their mid-twenties. This should be reassuring to all of us in our twenties that it’s okay not to have life figured out just yet, it might be because our frontal lobes are not quite done forming! Researching the frontal lobe has provided clarity as to why even the smallest bit of damage can be detrimental to cognitive functions. I can remember my mother getting upset with my brother and I when she would see us riding our bikes with no helmets on. Since the frontal lobe is most prone to concussions and traumatic brain injuries, I can see why helmet safety is always encouraged. Whether it’s for sports or for bike riding, helmets are extremely important and can prevent long term brain injury or even death.
REPSPONSE 2 :Cranial Nerves
Research
What are the 12 cranial nerves and their functions?
The 12 nerves are, the olfactory bulb 1, optic nerve 2, oculomotor nerve 3, trochlear nerve 4, trigeminal nerve 5, abducens nerve 6, facial nerve 7, vestibulocochlear nerve 8, glossopharyngeal nerve 9, vagus nerve 10, hypoglossal nerve 11, and lastly, accessory nerve 12. All these 12 nerves have a unique and very important purpose and function. For example, the olfactory nerve transmits information regarding a person’s sense of smell to the brain. The optic nerve transmits information to the brain regarding a person’s vision. The oculomotor nerve helps control muscle movements of the eyes. The trochlear nerve also has a role in eye movement. The trigeminal nerve is the largest cranial nerve and has both motor and sensory functions. The abducens nerve also helps control eye movements. The facial nerve also has both motor and sensory functions. The vestibulocochlear nerve helps with a person’s hearing and balance. The glossopharyngeal nerve possesses both motor and sensory functions. The vagus nerve has a range of functions, providing motor, sensory, and parasympathetic functions. The accessory nerve provides motor function to some muscles in the neck. The hypoglossal nerve is a motor nerve that supplies the tongue muscles. It originates in the medulla. (Johnson, s. 2022, June 5). Here are some fun facts about the nerves:
The vagus nerve is the longest cranial nerve as it starts in the medulla — the bottom part of the brain — and extends to the abdomen.
The shortest cranial nerve is the trochlear nerve, as it has the lowest number of axons. The twelve cranial nerves are a group of nerves that start in the brain and provide motor and sensory functions to the head and neck. Each cranial nerve has unique anatomical characteristics and functions. Doctors can identify neurological or psychiatric disorders by testing cranial nerve functions. (Johnson, s. 2022, June 5)
Did you know that 4 of the cranial nerves are concerned exclusively with the eyes ( 2, 3, 4, 6). (Saladin 2024).
Critical Thinking
I personally found this research super interesting. I love learning about the body and how everything is all connected. I find it fascinating how everything works and that 1 small thing has such a big purpose in our bodies. For example, looking at pictures of all the nerves, you can tell that everything is connected and they each have an important role in our bodies but what blows my mind is how some of them are connected to 1 specific part of our bodies yet do completely different things, so many things are happening inside of our bodies and we don’t even realize or feel it.

DISCUSSION 1:3. Synovial joints- subtypes, anatomy & example of each, Does this move?
Synovial Joints: Subtypes, Anatomy, and Movement
Synovial joints are the most common type of joint in the human body, allowing for a wide range of movements. They are unique because of their structure, which includes a fluid-filled synovial cavity, providing lubrication and reducing friction between the articulating bones. This essay will discuss the subtypes of synovial joints, their anatomy, and provide examples of each subtype along with their respective movements.
Anatomy of Synovial Joints
Synovial joints share several common features. They include:
1. Articular Cartilage: This smooth, slippery cartilage covers the ends of bones in a synovial joint, helping to reduce friction and absorb shock.
2. Synovial Cavity: A small space between the articulating bones, filled with synovial fluid, allows the bones to move freely.
3. Synovial Fluid: This lubricating fluid, secreted by the synovial membrane, reduces friction and provides nutrients to the cartilage.
4. Joint Capsule: A fibrous connective tissue that encloses the synovial joint, maintaining its integrity and providing stability.
5. Ligaments: These tough bands of tissue connect bones and support the joint by preventing excessive movement.
6. Tendons: Tendons attach muscles to bones, playing an essential role in controlling joint movement.
Subtypes of Synovial Joints
1. Hinge Joint
Anatomy and Movement: Hinge joints resemble the movement of a door hinge, allowing flexion and extension in a single plane. The articular surfaces of the bones are shaped to restrict movement to one axis.
Example: The elbow joint, where the humerus articulates with the ulna, is a prime example of a hinge joint. Flexion occurs when the forearm moves towards the shoulder, and extension happens when the arm straightens.
2. Pivot Joint
Anatomy and Movement: Pivot joints allow rotational movement around a single axis. This type of joint consists of a rounded or pointed bone that fits into a ring formed by another bone and a ligament.
Example: The atlantoaxial joint between the first and second cervical vertebrae (C1 and C2) allows the head to rotate from side to side. This is the joint responsible for shaking your head to indicate “no.”
3. Ball-and-Socket Joint
Anatomy and Movement: A ball-and-socket joint features a spherical head of one bone fitting into a cup-like socket of another bone. This configuration allows movement in multiple axes and planes, including flexion, extension, abduction, adduction, rotation, and circumduction.
Example: The shoulder joint, formed by the humerus and scapula, is an example of a ball-and-socket joint. It permits a wide range of movements such as raising the arms (abduction), rotating the arm (internal and external rotation), and moving the arm in a circular motion (circumduction).
4. Condyloid (Ellipsoid) Joint
Anatomy and Movement: Condyloid joints involve an oval-shaped end of one bone fitting into a shallow depression in another bone. These joints allow movement in two planes—flexion and extension, as well as abduction and adduction—but limit rotation.
Example: The wrist joint, between the radius and the carpal bones, is a condyloid joint. This joint allows flexion and extension, such as bending and straightening the wrist, as well as side-to-side movements (abduction and adduction).
5. Saddle Joint
Anatomy and Movement: In a saddle joint, both articulating surfaces have concave and convex areas, resembling a rider in a saddle. This joint allows movement similar to condyloid joints but with a greater range of motion.
Example: The carpometacarpal joint of the thumb, where the trapezium bone of the wrist meets the first metacarpal bone of the thumb, is a saddle joint. This joint allows for opposition of the thumb, enabling grasping and holding objects.
6. Plane (Gliding) Joint
Anatomy and Movement: Plane joints have flat or slightly curved articular surfaces that allow bones to glide past each other. These joints permit limited movement, typically in the form of sliding or twisting.
Example: The intercarpal joints of the wrist and the intertarsal joints of the foot are examples of plane joints. These joints allow for small, sliding movements, contributing to flexibility and shock absorption in the hands and feet.
Critical Analysis
Synovial joints are vital for the movement and flexibility of the body, playing a crucial role in daily activities, sports, and overall mobility. The design of these joints reflects the balance between stability and mobility. For example, the shoulder’s ball-and-socket joint offers an extensive range of motion but is more prone to dislocation due to its relatively shallow socket. Conversely, the hinge joints of the knee and elbow prioritize stability but sacrifice a degree of movement. This trade-off ensures that different parts of the body can perform specialized tasks.
Further research into synovial joints has led to medical advancements, such as joint replacement surgeries, which aim to restore function in damaged joints. Osteoarthritis, the degeneration of articular cartilage, is a common issue in synovial joints, particularly in weight-bearing joints like the knee and hip. Understanding the anatomy and function of these joints is critical in diagnosing, treating, and preventing joint-related disorders.
Conclusion
Synovial joints are a key component of the musculoskeletal system, enabling movement and providing flexibility. Their various subtypes—hinge, pivot, ball-and-socket, condyloid, saddle, and plane joints—are adapted to serve specific functions, whether it’s the powerful rotation of the neck or the delicate movement of the thumb. Understanding the anatomy and function of these joints not only enhances our knowledge of human physiology but also informs medical treatments and interventions aimed at maintaining joint health.
DISSCUSSION 2:10. The Shoulder joint: Bones that form it, Range of motion, common dysfunctions compared to normal structure
COLLAPSE
Research
The shoulder joint, also known as the glenohumeral joint, is one of the most flexible joints in our body, allowing us to reach up and toss a ball, among other things (Saladin, 2024). It is made up of three primary bones: the humerus (upper arm), the scapula (shoulder blade), and the clavicle. The humerus head fits into a small socket in the scapula known as the glenoid fossa, resulting in a ball-and-socket union. This provides for a wide range of motion; yet, because the shoulder lacks the stability of other joints, it is more susceptible to injury (Saladin, 2024).
The shoulder can move in practically any direction, up, down, forward, and backward and the shoulder joint can spin both inside and out. The shoulder’s adaptability accounts for its widespread use, but it comes at a cost. The rotator cuff muscles and tendons around the shoulder control whether the joint is fixed or free to move. However, this area is vulnerable to harm, particularly during times of strain or abuse (Mayo Clinic, 2023). Rotator cuff tears, which can occur from either unanticipated damage (AAOS, 2022) or recurring motion. Shoulder impingement, in which the tendons become compressed during movement If left untreated, these disorders may cause discomfort and reduced performance.
Critical Thinking
Given how much we rely on the shoulder joint for daily activity, I find it very interesting that despite the flexibility, the shoulder is very suspectible to injury. Shoulder difficulties appear to affect everyone, whether they engage in physical labor, sports, or at a desk. Shoulder injuries are particularly common among physically demanding workers in my area. It’s a major concern because these injuries not only create pain but also impede a person’s capacity to work or enjoy leisure activities.
The design of the shoulder is an excellent example of the tradeoff between rigidity and mobility. Despite our considerable freedom from it, there is a chance of damage. Understanding how the shoulder functions and what may go wrong emphasizes the need of treating our bodies. Avoiding repeated strain, improving posture, and strengthening the muscles that surround the shoulder will all assist to prevent injury.
Shoulder issue has a larger impact on society than we may realize. Many of us spend a significant amount of time on computers or at desks, which strains the shoulders and causes persistent difficulties. Part of this is due to increased awareness of posture and ergonomics. Maintaining our independence, especially as we age, is dependent on our shoulders remaining healthy for more than just physical reasons. Early preventive management is especially important because shoulder disorders can severely limit freedom and movement.

Discussion 1 : No. 13 Hair & Nails – functions & structure
RESEARCH
Nails and hair not only help in regulating our body temperature but also work as a protective guard against injury on our toes and fingers. They are both made of a major Keratin protein, a protein that heals wounds, keeps our skin, nails, and hair in its healthiest state. Hair grows directly from follicles in the “dermis of the skin “ which covers the entire body except for a few areas, like your lips and palms of your hands. Hair provides insulation and helps our heads preserve heat. It also protects the skin from damage caused by UV light and the sun. As we know hair moves with breeze or when someone touches us, that’s due to a sensory function it has. Nails are made from layers of dead keratin, the protein in keratin hardens the nail which is how they protect our fingers. There are a few parts to the nail: The plate, the root, cuticles, and nail plate.
The root of the nail is found under the skins surface near or at the end of the nail.
The nail plate is the part that’s external to the skin, the most visible part of the nail.
The nail bed is the pinkish area under the skin; it has the pink color due to vessels in the dermis.
Nails are also an essential area used by health care professionals to quickly determine the oxygen levels and blood flow around limbs. You can also recognize certain health issues with someone’s nails such as fungal infections. Nails & hair are important areas of the human body.
CRITICAL THINKING
Personally, I always considered hair and nails to be an aesthetic. Something we just maintain and keep up with to look a certain way, not knowing they have other purposes. Of course, the hair on my head keeps my head warm especially experiencing winter when I lived in the northeast. However, the thought never came to me of how it protects me from UV/sunlight. Nails are art for me, painting, cutting, and growing them, something I change on the regular. Now understanding the actual purpose of our nails, I will work to keep them as healthy as they can be because they are essential.
DISSCUSSION 2 -Membranes-types, functions, and serosa types and locations
Research
Every part of the body has a protector or systems that work together to keep them not only safe and protected but always moving. The four tissue membranes are Mucous (Epithelial), Serous, Cutaneous and Synovial (Connective). These membranes cover most of the body, are internal passages and line against joints. According to louispressbook.pub (2022), explains the membranes as they relate to the body system that are in. The Mucous membrane is usually found in multiple systems such as the digestive, respiratory, reproductive and urinary, with the job of keeping mucous always secrete. The Cutaneous membrane main job is to cover the body surface or what is known as the skin. Synovial membranes produce fluid with the joints. Last, the Serous membrane is closest to the outside/exterior of the body cavities such as the pericardial, peritoneal and the pleural (Saladin, 2024).
Serous cavities are known to reduce friction that may lead to inflammation of other organs by protection with various sizes and complexity. Three of the most important serous cavities are Pleura, Pericardium, Tunica Vaginalis and Peritoneum. Pleura surrounds the lungs to help reduce friction between the lungs and body walls. Peritoneum mostly surrounds the abdominopelvic cavity with reducing friction in those areas. Last, Pericardium main goal is to protect the heart and its’ walls. One serous membrane many may not know is the Tunica Vaginalis that is in males and surrounds the testes in males. (biologydictionary.net, 2017).
Critical Thinking
When these membranes do not function correctly or at a lower standard then our bodies need it may lead to other issues within other organs. As someone who currently works in corrections, being able to move, run, bend is apart of my job and if I have an injury to a body part or cavity it may make it hard to do daily task. For example, the connective tissue/synovial membrane covers the lining of body parts such as the kidney and joints. In my current and future job, as a nurse, I would have to stay hydrated to keep my kidneys and joints in good condition to not cause any harm to any other organ systems or body parts. My future goal as a nurse, will help me be able to explain to patients how important it is to stay hydrated, keep a good exercise routine, eat healthy and get adequate rest to avoid having any future decline in health.

Hepatitis BEtiology
Hepatitis B is an infectious disease acquired from the hepatitis B virus (HBV), which belongs to the Hepadnaviridae family. This virus has a pyrimidine-containing partially double-stranded DNA genome; it also has a nucleocapsid core and a lipid envelope housing crucial antigens that aid in detecting and advancing the disease. HBV is transmitted mainly through exposure to infectious body fluids such as blood, semen, and vaginal secretions; hence the main modes of transmission are through sexual practices, sharing of needles, and from mother to child (Pyrsopoulos, 2022). The pathophysiology of the disease reflects the virus infection and its outcome on the host immune system, which inflicts injury to the liver tissue and its inflammation, which may lead to cirrhosis and HCC.
Epidemiology
Hepatitis B is also a significant health issue that affects millions of people across the world, particularly in developing nations. It is estimated that about one-third of the world’s population has been infected with HBV, and 250-350 million worldwide are chronically infected. Chronic HBV infection incidence is not constant in all regions, particularly in sub-Saharan Africa, east Asia, and the Pacific Islands, where the rates rise to 20% (Conners et al., 2023). Currently, in the United States of America, new cases of acute HBV are significantly reducing due to vaccination. Yet, around 2 million people are suffering from chronic hepatitis B (SHB), particularly foreign-born individuals coming from highly endemic countries (Pyrsopoulos, 2022). Some of the other risk factors associated with infection with HBV are multiple sexual partners, use of infected needles, or direct exposure to blood at the workplace.
Clinical Features
The symptoms of hepatitis B vary from mild to severe and include jaundice, anorexia, nausea, weight loss, abdominal pain, fatigue, fever, chills, and dark urine. Most people get acute HBV infection, which can have symptoms or be asymptomatic; symptoms include jaundice, fatigue, abdominal pain, and dark urine (Pyrsopoulos, 2022). In some circumstances, acute liver failure can be an outcome of the disease. HBV infection can be safe for years with few or no symptoms and may progress to cirrhosis or HCC. Chronic hepatitis B is usually classified into three phases depending on viral replication and the liver enzyme levels of the patients, namely, the immune-tolerated phase, the immune-reactive phase, and the inactive phase. The immune-active phase is especially troublesome since there are higher rates of liver inflammation and disease progression to cirrhosis and HCC.
Diagnosis
The routine tests used to diagnose hepatitis B include serology, biochemical, and imaging. The key serological markers for the hepatitis B virus include hepatitis B surface antigen (HBsAg), hepatitis B e antigen (HBeAg), and antibodies for these antigens: anti-HBs and anti-HBe (Conners et al., 2023). HBsAg is present during an acute HBV infection, while anti-HBs are present when the persons have been infected or received the hepatitis B vaccine. Some of the biochemical tests used to check liver function include Serum Alanine aminotransferase (ALT) and aspartate aminotransferase (AST) levels, Bilirubin levels, and Albumin levels (Pyrsopoulos, 2022). Diagnostic procedures like abdominal ultrasound and MRI can be used to assess the degree of liver injury and diagnose complications like cirrhosis or HCC. Liver biopsies may be done in order to determine the severity of the liver disease in patients with chronic HBV infection (Pyrsopoulos, 2022).
Complementary Exams
Complementary exams for hepatitis B are integrated with advanced imaging techniques to evaluate liver function and disease progression. Liver biopsy is replaced by FibroScan, an invasive free method that determines the stiffness of the liver to evaluate fibrosis and cirrhosis in patients with HBV (Pyrsopoulos, 2022). Further, the known photoelasticity method, magnetic resonance elastography (MRE), depicts the intensity of the fibers and signs of early fibrosis in the liver. These tests are essential when caring for patients with chronic hepatitis B virus infection since they can predict treatment and possible outcomes. Monitoring HBV DNA levels in patients regularly to assess antiviral response and resistance development is also pivotal.
Treatments
The main aims of hepatitis B treatment are to halt the disease progression, suppress virus replication, and decrease the risk of developing cirrhosis and HCC. Lifestyle change and antiviral therapy are some accepted approaches to treating the illness. Standard agents, which include tenofovir disoproxil fumarate, entecavir, and pegylated interferon-alpha, have been observed to have a high efficiency in the reduction of HBV DNA and improvement of the liver (Pyrsopoulos, 2022). Also, it is documented that for patients with decompensated cirrhosis, liver transplantation is the only curative approach. Additionally, there are counsels like sticking to low-sodium products and not consuming any alcohol to minimize liver injury and aspire for an enhanced standard of health (Pyrsopoulos, 2022). The guidelines of appropriate and efficient antiviral treatments and follow-up can make chronic HBV infection control easier.
