Ligaments Joints and bones are held together by fibrous, strong, and flexible ligaments. Their cohesive qualities provide stability and prevent injury. The three main ligaments of the elbow include:. Tendons Tendons are soft tissue that connect muscles to bones to provide support and smooth movement.
Tendons connecting in or through the elbow include:. Nerves Nerves carry signals between your brain and your elbow and play a key role in pain, touch, hot, and cold sensation — and also help control muscle movement. The three main nerves of the arm are:. All three of these nerves originate in the shoulder and extend downward through the elbow and along the arm.
The ulnar nerve is the largest and busiest of the three. The olecranon burse is the most commonly irritated. Common conditions affecting the burse include Elbow Bursitis and Olecranon Bursitis.

Find a Location Bone and Joint The three bones that make up the elbow joint are the humerus upper arm, and the two bones of the forearm, the radius and ulna. Muscles The anterior muscles of the arm are the biceps, brachioradialis and brachialis. Ligaments Ligaments are strong connective tissue structures that join bone to bone, providing stability to the elbow. Burse A burse is a fluid filled sac that decreases friction between two tissues.

The cartilage of the elbow is thinner than that of weight-bearing joints, such as the knee or hip. Tough bands of connective tissue called ligaments hold the bones of the elbow together. The two main ligaments connecting the humerus and ulna are:.
A third major ligament of the elbow is the annular ligament, which circles the top, or head, of the radius, holding it against the humerus. The ligaments form a capsule around the joint that is lined with a smooth membrane called the synovium.
The synovium produces a viscous liquid, called synovial fluid, which lubricates the joint. Several muscles surround the elbow, making it possible for you to move your arm.
The two main muscles responsible for bending and straightening the arm at the elbow are:. Get involved with the arthritis community.
