leddskapsel

Leddskapsel, also known as the ligament capsule, is a fibrous tissue structure that surrounds and stabilizes joints in the human body. It is a vital component of synovial joints, providing both support and flexibility. The capsule encompasses the joint cavity, enclosing the synovial fluid that lubricates the joint and nourishes the articular cartilage.

Structurally, the leddskapsel consists primarily of dense irregular connective tissue, made up of collagen fibers that offer strength and elasticity. Its thickness and robustness can vary depending on the joint's functional demands. The capsule typically attaches to the periosteum of the bones that form the joint, enveloping the articulating surfaces.

Functionally, the leddskapsel plays a critical role in joint stability, guiding movement, and preventing excessive or dislocating motions. It houses nerve fibers that provide proprioceptive feedback, contributing to the coordination of muscle activity around the joint. Blood vessels within the capsule supply the synovial membrane and surrounding tissues.

In many joints, the capsule is reinforced by additional ligaments, tendons, and muscles, which work together to maintain structural integrity and facilitate complex movements. Conditions such as capsulitis, or inflammation of the capsule, can lead to pain and restricted movement, often resulting from injury or degenerative changes.

Overall, the leddskapsel is essential for proper joint function, balancing stability and mobility while allowing for smooth, controlled movements necessary for daily activities.
