Document Summary

Myology consists of muscles that contract to move or position parts of the body (eg, the bones that articulate at joints) Muscle cells are called muscle fibers long and narrow when relaxed. Functions: provide static support (create form, allow movement, provide heat. Cardiac striated muscles forms the walls of the heart and adjacent parts of the greater vessels. Regulated via pacemaker special cardiac muscle fibers. Smooth muscle forms the walls of most of our hallow organs, move substances through organs, viscera, and control movement through blood vessels. Pennate muscles are feather like in the arraignment of their fascicles (fiber bundles): unipennate, bipennate, or multipennate. Fusiform muscles spindle-shaped (round, thick belly, and tapered ends) Parallel muscles the fascicles lie parallel to the long axis of the muscles, flat muscles with parallel fibers often have aponeuroses. Convergent muscles have a broad attachment from which the fascicles coverage to a single tendon. Pectoralis major many sources of attachment converge together on humerus.
