The elbow joint, a crucial hinge connecting the upper arm to the forearm, orchestrates a remarkable range of motion. Formed by the articulation of three bones – the humerus of the upper arm and the radius and ulna of the forearm – it enables us to flex and extend our arm, as well as rotate our forearm.

Ligaments, strong fibrous tissues, crisscross the joint, providing stability and preventing excessive movement. Muscles such as the biceps and triceps brachii power the bending and straightening actions, while nerves like the ulnar, median, and radial traverse the elbow, relaying vital sensory and motor information.

Given its pivotal role in countless daily activities, the elbow, like the hand and wrist, is susceptible to injury and strain, underscoring the importance of understanding its intricate anatomy for maintaining its health and function.
