Imagine:
A person is posing while resting on a small, narrow platform that only supports their trunk, neck and head.
They are in a horizontal, prone, position.
Their limbs are arranged as described below and they must contract some appendicular skeletal muscles to maintain the position of the limbs.
Required arrangement of the limbs:
Hands and fingers extended
Forearms pronated
Forearms flexed at the elbow
Arms at a 90 degree angle from the trunk (i.e., straight down)
Thighs horizontal to the ground and abducted
Legs vertical (flexed at knee)
Feet plantarflexed at ankle
Scapulae adducted (assume that the rhomboid major and minor muscles and the trapezius muscle (middle fibers) are the prime mover muscles responsible for scapular adduction)
The assignment: Name and describe the prime mover appendicular muscles (see Prime Mover Skeletal Muscle Info or most important appendicular muscle groups (if there are/is no prime mover(s) listed in Prime Mover Skeletal Muscle Info Download Prime Mover Skeletal Muscle Info) that must be contracted to maintain the pose plus the innervation of the relevant muscles (see Tables in Tortora Ch. 11 and 17 for innervation of muscles).
Organize your description by the appendicular joint(s) at which movement of the relevant body part occurs.There must be only 8 paragraphs in your essay. The first 7 paragraphs must be about the prime mover muscles that must contract to maintain the pose at a specific appendicular joint plus innervation for each muscle (specify which nerve innervates which muscle). The 8th paragraph should address scapular adduction.
NUMBER YOUR PARAGRAPHS as follows:
Fingers/wrist (gross movements caused by forearm muscles – don’t include intrinsic hand muscles)
Distal & proximal radioulnar joints
Elbows
Shoulders
Hips
Knees
Ankles (talocrural joint)
Scapulae
