The Poser Essay is a Lab Assignment:
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 Download 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
NOTE: You must use the information in Tortora Chapters 11 and 17 and the Prime Mover Skeletal Muscle Info Download Prime Mover Skeletal Muscle Infotables for this assignment. No outside sources!
You are required to do this by yourself, using Tortora information & the Prime Mover Skeletal Muscle Info Download Prime Mover Skeletal Muscle Infotables, although you may ask me questions about the assignment.You may email me a preliminary version of the assignment for feedback.
The prime mover muscles that you must discuss in this essay for paragraphs 1-7 are all in Prime Mover Skeletal Muscle InfoDownload Prime Mover Skeletal Muscle InfoFor paragraphs 1-7, do not name muscles with actions at the joint if they are not listed as prime movers for the required action in Prime Mover Skeletal Muscle InfoDownload Prime Mover Skeletal Muscle Info
The information concerning scapular adduction (paragraph 8) may be found in Tortora.
Required File Naming Format: The filename must be as follows: lastname-first initial-section#.xxx, where xxx is doc, docx, or pdf, depending on the file type you saved (e.g., for a student with the last name Adam Smith, in section #1000, an doc file would be smith-a-1000.doc).
