Elbow Joint Anatomy and Function

This video provides a comprehensive overview of the anatomy of the elbow joint, a hinge-type synovial joint connecting the humerus, radius, and ulna. It covers the articular surfaces, joint capsule, synovial membrane, ligaments, muscles, nerve supply, and blood supply. The video explains the roles of different ligaments and muscles in joint stability and movement, including flexion, extension, pronation, and supination. It also details the nerve and blood supply essential for joint function.

What type of joint is the elbow joint?

• Saddle joint

• Hinge type of synovial joint

• Pivot joint

Which bones are involved in the humero-ulnar articulation?

• Capitulum of humerus and head of radius

• Radial artery

• Ulnar artery

• Axillary artery

• Brachial artery

Which artery supplies the lateral aspect of the forearm?

• Brachial artery

• Radial artery

• Subclavian artery

Which artery supplies the medial aspect of the forearm?

• Ulnar artery
