Final answer:
The elbow joint is a hi`nge joint that allows for flexion and extension of the forearm. It includes the humeroulnar joint, humeroradial joint, and the proximal radioulnar joint. Ligaments provide support and prevent side-to-side movements.
Step-by-step explanation:
The elbow joint is a hi nge joint that allows for flexion and extension of the forearm. It is formed by the articulation between the trochlea of the humerus and the trochlear notch of the ulna.
The elbow joint also includes the humeroradial joint and the proximal radioulnar joint, which allow for rotation of the radius during pronation and supination of the forearm. Ligaments, such as the ulnar collateral ligament and the radial collateral ligament, support the elbow joint and prevent side-to-side movements.
