Study Notes
Elbow X-ray Labeling
-
Ulna: A bone in the forearm that forms the inner side of the elbow joint; identifiable by its U-shaped structure that curves around the radius.
-
Radius: The lateral bone of the forearm, situated on the opposite side of the ulna; plays a critical role in wrist and forearm movement.
-
Humerus: The long bone in the upper arm extending from the shoulder to the elbow; articulates with both the ulna and radius to form the elbow joint.
-
Trochlear Notch of Ulna: A deep, curved indentation on the ulna that fits over the trochlea of the humerus; essential for hinge-like movement at the elbow.
-
Olecranon Process: The bony prominence of the ulna at the elbow; serves as a lever for the triceps muscle, facilitating arm extension.
-
Coracoid Process: A small, hook-like structure on the scapula that provides attachment for several muscles, although not directly involved in the anatomy of the elbow.
