Elbow Joint Anatomy and Function

The video provides an in-depth look at the anatomy of the elbow, focusing on the bones, joints, and ligaments. It begins with an introduction to the elbow model, followed by a detailed explanation of the bones involved: the humerus, radius, and ulna. The video then explores the joints and movements of the elbow, including the hinge and pivot joints responsible for flexion, extension, supination, and pronation. The bony features of the humerus, radius, and ulna are described, highlighting key structures like the supracondylar ridges and fossae. Finally, the video covers the ligaments that support the elbow joint, such as the lateral and medial collateral ligaments and the annular ligament.
