What is a articular capsule?
What is a articular capsule?
The articular capsule surrounds the joint and is continuous with the periosteum of articulating bones. It consists of two layers: Fibrous layer (outer) – consists of white fibrous tissue, known the capsular ligament. It holds together the articulating bones and supports the underlying synovium.
What are the 2 main functions of the articular capsule?
The joint capsule, ligaments, and tendons serve to stabilize the joint, distribute the biomechanical load on the joint and protect the joint by limiting its normal range of motion. The joint capsule is comprised of fibrous connective tissue and inserts into the bone near the articulating surfaces.
What is the function of the articular capsule internal layer?
The joint is enclosed by a connective tissue that forms the articular capsule. The articular capsule is composed of two distinct layers and reduces friction at the joint. The internal layer consists of a thin synovial membrane, which secretes synovial fluid into the synovial cavity and lubricates the joint.
What forms articular capsule?
The ends of the joint bones are covered with smooth, glass-like hyaline cartilage which reduces friction during movement. A synovial joint contains a synovial cavity and dense, irregular connective tissue that forms the articular capsule normally associated with accessory ligaments.
What is the function of the fibrous capsule in the kidney?
renal capsule, thin membranous sheath that covers the outer surface of each kidney. The capsule is composed of tough fibres, chiefly collagen and elastin (fibrous proteins), that help to support the kidney mass and protect the vital tissue from injury.
What is the function of the articular cartilage?
Articular cartilage is the smooth, white tissue that covers the ends of bones where they come together to form joints. Healthy cartilage in our joints makes it easier to move. It allows the bones to glide over each other with very little friction. Articular cartilage can be damaged by injury or normal wear and tear.
What does the articular cartilage do?
What are the 4 main characteristics of synovial joints?
Synovial joints comprise most of the joints of the extremities and are the most accessible joints to direct inspection and palpation. Synovial joints share important structural components: subchondral bone, hyaline cartilage, a joint cavity, synovial lining, articular capsule, and supporting ligaments.
What is perirenal fat and what is its function?
What is the purpose of the perirenal fat capsule? It’s the fatty cushion that prevents kidney from being damaged or even rupturing due to trauma/injuries.
