1. Shoulders The shoulder joint is a ball-and-socket joint that connects the upper arm bone (humerus) to the shoulder blade (scapula). This joint allows us to move our arms forward and backward, rotate them inward and outward, and raise and lower our arms. 2. Biceps The bicep muscle is responsible for flexing the elbow. It can be further divided into three parts: the long head, the short head, and the lateral head. 3. Triceps The triceps are a group of muscles located at the back of the upper arm. They include the brachialis, the brachioradialis, and the anconeus. These muscles allow us to extend our elbows. seeing 777
