Class Summary - Today we discussed / reviewed the types of muscle (smooth, cardiac and skeletal) and functions of the skeletal muscles which we will focus on this chapter. We talked about the connective tissues endomysium (surrounding each fiber), perimysium (surrounding each fasicle) and the epimysium (surrounding the muscle itself). The endomysium becomes facia which also becomes tendons. We talked about origin of the muscle is at the place where the stationary bone is and the insertion of the muscle is where the movable bone is. We talked about prime muscles being the muscle that does the most work in movement and that synergists assist the prime mover. We also talked about antagonistic muscle groups. We talked about different clues to naming muscles including size, shape, direction of fibers, location, attachment, number of attachment and action.
Objectives - Students will distinguish between the three types of muscles and tell where they are located in the body, describe the connective tissues of a skeletal muscle, name and discuss five functions of skeletal muscle, and discuss how muscles work together to achieve the movement of bone
