Melissa is practicing her golf swing at a driving range.

has anyone got the answers to the scin 132 anatomy and ohysiology for assignment one about mellisa and the golf club please

Interested in the same info...sorry I couldn't help though...

I have been searching everywhere for it too and I can only find help with Part 1. and NOTHING for Part 2. Sorry

Here's what I submitted today. I got my info frOm my wife
 Advance Anatomy and physiology book so it's not click and pasted check out and modify at your own will but I'm confident it's pretty solid.

Part 1: Muscles, Joints and Bones Anatomy
A. phalanges, metacarpals, Carpals, ulna , radius, humerus, clavicle, scapula, the spinal cord and supporting vertebrae, sternum, rib cage
 
B.  metacarpalpophalangeal (hinge),metataropshalangeal (hinge) radiocarpal (biaxial or multiaxial, radioular,proximal distal (pivot/monoaxial), cubital/elbow(hinge/monoaxial),
Glenohumeral(ball and socket), acromioclvicular(plane/multiaxial), costovertebral (plane/multiaxial
 
C.Triceps deltoid, and pectoralis major along with lattissimus dorsi both adduct flex and extend both shoulders. The coracobrachialis adducts arms and flexes the shoulders along with the assistance from subscapularis,supraspinatus, teres minor, and infraspinatus laterally rotate the arms outward and down holding the humerus in place, also the  trapezius and serratus anterior muscles have aided in the stabilization to the fore arms the flexor carpi radialis along with flexor digitorium superficialis and flexor pollicis longus work together with Palmaris longus to complete the stance of arms extended down and grasping the golf club, while the most important of muscles utilized in a golf swing the abdominals , obligues, and torso provide the rotation and torque to propel a golf ball 
 
 
Part 2: Nervous System and Muscle Physiology
D. From the cerebral cortex whose axons form pathways, synapse directly with lower motor neurons or groups of nerve fibers, for Melissa her corticospinal tract which is involved in direct control of movement below the head. Most of the corticospinal fibers synapse with interneurons in the lateral portions of the spinal cord central gray matter. The interneurons in turn synapse with the lower motor neurons of the anterior horn that innervate primarily distal limb muscles like the arms and hands of Melissa.
 
E. I choose the Ulnar Nerve which is a peripheral nerve of the medial cord which influences the movement of  the wrist and fingers, and specifically innervates two of the fore arm muscles, flexor carpi ulnaris and flexor digitorium profundus plus most of the intricate hand muscle which have a valuable asset in the grasp of a golf swing. To note in summary an impulse from the central nervous system travels down a preganglionic neuron causing a release of a chemical that can bind to a receptor on the cell body of the post ganglionic neurons and will release chemicals that bind to receptors on the target muscles, the main chemical released are acetycholine and noradrenaline. These are released from neurons, all neurons leaving the central nervous system release acetylcholine.
 
F. The sliding filament theory of muscle contraction includes all the events that result in actin myofilament sliding over myosin myofiliaments to shorten the sarcomeres of muscles fibers. Actin and myosin myofilaments  do not change length during contraction of skeletal muscles. Instead the actin and myosin myofilaments  slide past one another in a way that causes the sarcomeres to shorten. The shortening of the sarcomeres is responsible for the contraction of skeletal muscles. When sarcomeres shorten the myofibrils also shorten because the myofibrils consist of sarcomeres joined end to end. The myofibrils extend the length of the muscle fibers and when they shorten the muscle fibers shorten. Muscle bundles  are made up of muscle fiber and muscles are made up of muscle bundles. There fore when sarcomeres shorten, myofibrils, muscle fibers, muscle bundles, and muscles shorten to produce muscle contractions.
