Read the information, do some independent research, and answer the questions that follow:
Osteoporosis is defined by the World Health Organization (WHO) as having a T-score less than -2.5. Some people have low bone density. You may hear this condition called osteopenia. Osteopenia is defined as 10% to 25% below peak adult bone mass, or a T-score between –1.0 and –2.5 standard deviations below normal. Having a T-score between -1.0 and -2.5 is not “pre-osteoporosis” but it is very important for people with low bone density to develop a good plan to prevent bone loss and osteoporosis.
Answer the following questions:
Why are hip and lumbar vertebrae regions used fo r assessment of bone density?
What are some health-related complications associated with osteoporosis?
Is a T-score of -2.2 considered normal, osteopenia, or osteoporosis?
Is a T-score of 0 considered normal, osteopenia, or osteoporosis?
Describe two preventative measures reducing chances of developing osteoporosis.

Answer the following questions based on the scenario and article above and save your responses in a Microsoft Word document. Provide a 1 scholarly resource in APA format to support your answers.
Trace the flow of urine from the collecting duct to the urethral meatus. Based on your knowledge of the male urinary tract, what normal organ is most likely obstructing the urinary outflow? Based on the anatomic location of this structure, how can this structure be examined? Based on your knowledge of anatomical differences, why are women more likely than men to get urinary tract infections? Predict the consequences of the inability to empty the bladder.

Glomerular filtration rate is a measurement of the volume of ultrafiltrate produced by all the nephrons in the kidneys every minute. This process is crucial for maintaining a balance between the removal of excess solutes and water from the blood while ensuring that essential substances are retained. The GFR rate is tightly regulated to ensure that the kidneys are functioning correctly and efficiently (Ditki.com, 2022).
The glomerular filtration rate (GFR) is constantly regulated and stabilized by two mechanisms: tubuloglomerular feedback (TGF) and the myogenic response. These mechanisms work together to ensure that GFR and distal salt delivery remain stable, even when blood pressure fluctuates (Saladin, 2020). This protects the kidney from the damaging effects of hypertension (Saladin, 2020). The myogenic response mechanism enables the kidney to maintain a consistent blood flow and glomerular capillary pressure in response to changes in the delivery of sodium chloride to the macula densa. When NaCl levels rise at the macula densa, the myogenic response of afferent arterioles constricts, lowering the single-nephron GFR. In tubuloglomerular feedback (TGF), a rise in NaCl levels at the macula densa causes constriction of the glomerular afferent arteriole, which also lowers the single-nephron GFR (Saladin, 2020). These two mechanisms work in tandem to regulate GFR and protect the kidney from the harmful effects of hypertension.

Part A
This assignment consists of five questions. Each of your responses should be one or more paragraphs long, depending upon the depth of the question. An answer consisting of only a few short sentences is insufficient and will receive a poor grade. Be sure to cite any and all sources correctly so that your academic integrity is not called into question.
Copy the following questions, add your answers, and submit them below in one attached document.
1. Describe the different levels of organization within the peripheral nervous system. Why do you think there are multiple motor divisions but only one sensory division? 2. Describe the difference in the function of hyperpolarization in action potentials vs. hyperpolarization in graded potentials. 3. Explain the difference between an electrical synapse and a chemical synapse. Which types of tissues will use electrical synapses? Which tissues use chemical synapses? 4. Discuss the primary functions of cerebrospinal fluid. How does the arrangement of the CSF network facilitate the spread of diseases such as meningitis throughout the nervous system?
5. Chapter 12 discusses the importance of sleep to healthy human physiology. Discuss the stages of sleep and what consequences may result from interrupting sleep in various stages.
NOTE: Your essay answers to these questions MUST be in your own words. Do not copy/paste any text into your answers unless you are including a properly cited brief direct quotation. I am looking for your own explanations—this is your opportunity to demonstrate what you know about these topics. The best approach will be to pretend you are explaining things to someone you are tutoring.
Part B
What are some common misconceptions about the brain? Post what you know about one or more of these topics, or conduct some basic research and share what you learn: the reptilian brain, left/right brains, brain death, etc. Why do you think these ideas are perpetuated if they are inaccurate?
Original Post – Present your outside source(s) and then summarize, in your own words, the misconception that you researched and why people still believe it. Be sure to cite your source and include a link or copy/paste (References) a direct quotation from the most relevant portion of the source to enable your classmates to view and evaluate the information.

Initial post:
A nutrient is a substance in food that is used by the body to promote normal growth, maintenance, and repair. During metabolism, substances inside body cells are constantly built up or broken down. Let’s start this week’s discussion with the definition and comparison of glycogenesis, glycogenolysis, gluconeogenesis, and lipogenesis. Which is (are) likely to be occurring (1) shortly after a carbohydrate-rich meal and (2) just before waking up in the morning?
Use your own words. Use 2 scholarly sources. APA format. cited.

According to the text, “Glycogenesis is the synthesis of glycogen; glycogenolysis is its hydrolysis (breakdown to glucose); and gluconeogenesis is the synthesis of glucose from noncarbohydrates, especially fats and proteins.” (Saladin, 2020 p. 641). It also says, “Synthesizing fats from other types of molecules is called lipogenesis,” (Saladin, 2020 p. 993). It could be known as triglyceride synthesis, as well. Now, glycogenesis is more likely to happen after eating a meal very rich in carbs, while gluconeogenesis is more likely to happen right before you wake up in the morning. NIH writes, “Lipogenesis encompasses the processes of fatty acid synthesis and subsequent triglyceride synthesis, and takes place in both liver and adipose tissue.” It’s also likely for lipogenesis to happen after eating a lot of carbs in one sitting.

The digestive system is composed of two parts: the alimentary canal and the accessory digestive structures. These two parts of the system work together to break down food into absorbable units and eliminate the non-digested material as feces. Let’s begin by identifying each of the organs in the alimentary canal and the accessory digestive structures.
Choose one organ/structure and post details about it to begin the discussion. Choose a different organ for each of your follow up posts to ensure everyone has an opportunity to contribute.

Hello class!
The GI tract is in-charge of ingestion and digestion of food, nutrient absorption, secretion of water and enzymes, and defecation. Organs involved in the GI tract consists of the oral cavity, pharynx, esophagus, stomach, small intestine, and large intestine. Accessory organs include the teeth, tongue, and glandular organs such as salivary glands, liver, gallbladder, and pancreas.
Most people care about their teeth for appearance, but do not know how valuable teeth are to digesting foods. Teeth contribute to mastication. Mastication is the act of chewing, and breaking down food into smaller, more digestible patterns. This is the first step of mechanical digestion. Without teeth foods such as meat and vegetables would not be digested properly. Adults have 32 teeth used for mastication of food. Each type/shape of tooth, has a different purpose. Incisors are shaped to the bite pieces of food, canines are shaped to pierce and shred meat, and molars are shaped to breakdown the food through crushing and grinding. Mastication relies on several other muscles in order to successfully breakdown the food. The tongue, buccinator, and orbicularis oris are needed to manipulate food and push it between the teeth creating the up-down grinding. Use your own words. APA format. Use 1 scholarly sources. Cited.
