Fibrous capsule

Fibrous Capsule

A Fibrous Capsule is a type of connective tissue that surrounds organs and other structures in the body. It is composed of dense irregular connective tissue, which provides strength and support to the organ or structure it encloses.

Structure

The fibrous capsule is made up of two layers: the outer fibrous layer and the inner synovial layer. The outer fibrous layer is composed of dense irregular connective tissue, which provides strength and support. The inner synovial layer is composed of loose connective tissue and produces synovial fluid, which lubricates the joint and reduces friction.

Function

The primary function of the fibrous capsule is to protect the organ or structure it surrounds. It provides a barrier against physical damage and infection. In addition, the fibrous capsule helps to maintain the shape of the organ and prevent it from over-expanding.

In the case of synovial joints, the fibrous capsule also plays a crucial role in joint movement. The synovial fluid produced by the inner layer of the capsule lubricates the joint, reducing friction and allowing for smooth movement.

Clinical Significance

Damage or disease affecting the fibrous capsule can lead to a range of health problems. For example, in osteoarthritis, the fibrous capsule of the affected joint can become inflamed and thickened, leading to pain and reduced mobility. In kidney disease, damage to the fibrous capsule can impair the kidney's ability to filter waste from the blood.
