1. The latissimus dorsi is a large back muscle responsible for the bulk of adduction of the arm (pulling the arm to the sides of the body). The teres major is a much smaller muscle that helps to start adduction of the arm when it is fully extended. Which muscle is the agonist, and why?

2. The pectoralis major is involved in the bench press exercise in which the arms flex towards the middle of the body. This muscle is proximally attached to the shoulder via the clavicle and chest via the sternum, while distally attached to the humerus. Identify the origin and insertion of the muscle respectively.
