The biceps tendons attach the biceps muscle to the shoulder. Your shoulder is a ball-and-socket joint made up of three bones: your upper arm bone (humerus), your shoulder blade (scapula), and your collarbone (clavicle). The head of your upper arm bone fits into a rounded socket in your shoulder blade.
The muscles throughout your arms are responsible for controlling movement at your elbow and wrist joints. The major muscles that make your upper arms look bigger when developed include your biceps brachii and triceps brachii muscles. Developed shoulders also contribute to a large arm appearance. There are also muscles throughout your forearms that flex, extend and rotate your wrists, and these muscles can make your lower arms look bigger.
