MEDICAL PHYSIOLOGY

Detailed explanation-1: -The elbow is a hinged joint made up of three bones, the humerus, ulna, and radius. The ends of the bones are covered with cartilage. Cartilage has a rubbery consistency that allows the joints to slide easily against one another and absorb shock. The bones are held together with ligaments that form the joint capsule.

Detailed explanation-2: -The elbow is a more complex hinge joint that forms between the humerus of the upper arm and the ulna and radius of the forearm. So, the correct answer is ‘Hinge’.

Detailed explanation-3: -The elbow joint is a synovial joint found in the upper limb between the arm and the forearm. It is the point of articulation of three bones: the humerus of the arm and the radius and the ulna of the forearm. The elbow joint is classified structurally as a synovial joint.

Detailed explanation-4: -The elbow joint is composed of the distal end of the humerus and the proximal ends of the radius and the ulna (see the images below).

Detailed explanation-5: -At the elbow, the humero-ulnar joint (the true elbow joint) is a hinge joint similar to the knee.
