The elbow is a joint in the human body that connects the upper arm to the forearm. It allows for bending and straightening of the arm, enabling various movements such as lifting and throwing. The elbow consists of three bones: the humerus, radius, and ulna. Ligaments and tendons support the joint, providing stability and flexibility. In addition to its primary function, the elbow plays a crucial role in daily activities, from eating to sports. Common injuries include tennis elbow and golfer's elbow, which result from overuse or strain. Proper care and exercise can help maintain elbow health.
