What is an articular capsule?

The

joint capsule is located in an area where two or more adjacent bones meet to form a synovial or movable joint such as a shoulder or knee. Usually bounded ligaments, fibrous connective tissue that holds the articulated bones together, contains cartilage to pour the bones against each other and a synovially filled cavity to lubricate the joint against any friction. These are located in the interior of two layers of articular capsule, Synoviale stratum or synovial membrane. On the outside of this membrane is a fibrosum layer that consists of fibrous tissue, which is not unlike the one that forms the liga.

While the tissue outside the joint capsules is relatively dense and fibrous, that it is thin, that it is thin, that it is thin, that the fine tissue cavity - namely synovial fluid. Synovial fluid, viser and jelly-like, is excreted in the membrane itself and fills not only the space in the cavity, but also any gaps in the articular cartilage that cover the ends of the articulated bones. He is pushed during movementAround the joint moving tissues and maintain friction formed bones that wipe around them to a minimum.

The

cartilage in the articular capsule acts as a type of bumper, which prevents neighboring bones in direct contact and reduces the impact strength, as in the knee during walking. In some synovial joints, such as the shoulder, there is a certain distance between the cartilage ends of the joint bones, which potentially reduces friction in the joint and allows for more movement. The articular cartilage receives nutrients from the synovial membrane, which, unlike the cartilage, penetrates capillaries supplied by filled nutrients, allowing it to maintain volume and elasticity.

Inflammation of articular capsules is a widespread pathology, better known as arthritis. There are many different species that affect synovial joints and damage the cartilage inside, but two forms are particularly common. Rheumatoid arthritis is characterizedOn several conditions that irritate cartilage by preventing it from receiving nutrients, such as a surplus of synovial fluid, which suffocates cartilage or synovial cells overproduction, which can then consume all nutrients entering the membrane joint. Osteoarthrosis, also known as degenerative joint diseases, involves degeneration of cartilage due to injury, illness, age or inheritance and is the number one form of arthritis.
