Document Summary

Lecture 5 neuromuscular aspects of movement i. The muscles overlay the skeleton and provide the means to move it. Each muscle produces a motion when it creates tension and tries to shorten: need a bunch of muscles to move a joint. Its attachments and orientation determine what moves and how: attachment sites, can wrap around things. Note the different shapes and wrappings of the muscles. Note the different alignment of the fibers within the muscles. Note the size (large or small) of the tendon attachments at either end: tendons attach muscle to the bone, several muscles can attach to the same tendon. Number of different heads within the same muscle can do different tasks cause they pull in different directions. Superficial muscle: closer to top of muscle. Deep muscles: under the top layers. Origin: the proximal attachment of a muscle, originates at origin goes out to insertion. Insertion: the distal attachment of a muscle.
