The arm is the region of the upper limb found between the shoulder and the elbow and consists of one bone, the humerus. Together with the scapula, they form the two main bony elements of the shoulder joint.
The humerus is the longest and largest bone of the upper limb. It articulates with the scapula proximally at the glenohumeral joint, which is a fancy name for shoulder joint. Distally, it articulates with the ulna an radius to form the elbow joint.
The scapula, also known as the shoulder blade, is a flat triangular bone found at the back of the trunk. It lies over the posterior surface of the ribs two to seven. When it articulates with another bone known as the clavicle, the scapula forms the shoulder girdle, which is what connects the appendicular skeleton to the axial skeleton.
