Humerus Anatomy is a long bone in the arm or forelimb that runs from the shoulder to the elbow, which connects the scapula and two bones of the lower arms. The humerus acts as an attachment site for many muscles and ligaments, resulting in various raised roughening on the bony surface.
Important Anterior Features:
Head: The ball of the “ball and socket” joint. Articulates with glenoid fossa of scapula.
Anatomical and Surgical Necks: Connect head to the rest of the bone. Anatomical is proximal to Surgical.
Important Posterior Features:
Radial Groove: The only relevant posterior groove
Olecranon Fossa: The most distal feature of the posterior view.
