Muscular System 2

Muscular System II: Professor Diamond continues her discussion of human muscle systems, addressing muscles of the trunk and upper extremity. Professor Diamond begins by discussing the trapezius, its origin and insertion, and how this relates to its function as an adductor. She encourages students to engage in self-study in order to grasp muscular form and function. She then explains the origin and insertion of the latissimus dorsi, pectoralis major, and deltoid muscles and how this relates logically to their function within the body. She closes by beginning to discuss the muscles of the arm, describing the four muscles of the rotator cuff and the bicep brachii muscles.
