Shoulder Capsule

The shoulder capsule is a soft, flexible envelope of tissue that surrounds and stabilizes the shoulder joint, holding the ball-and-socket components in place. Made of strong connective tissue, it allows the shoulder to move freely while maintaining stability. The capsule contains synovial fluid, which lubricates the joint and reduces friction during movement. Injuries or inflammation can cause the capsule to tighten or thicken, limiting motion and causing discomfort. Overall, the capsule plays a crucial role in both the mobility and stability of the shoulder joint.
