Articular Capsule

Articular Capsule

Question 1. Histology of temporomandibular joint.
Answer:

• The articular disc is made up of type I collagen.
• The articular surfaces of the temporomandibular joint are covered with fibrous tissue.
• The capsule is lined on its inner surface by a synovial membrane.
• The synovial membrane lines the entire capsule with folds or villi of the membrane protruding into the joint cavity.
• The synovial membrane consists of two layers.

Cellular intima:

• It has one to four layers of synovial cells embedded in an amorphous, fiber-free intercellular matrix.

Vascular subintima:

• It is a loose connective tissue containing vascular elements along with scattered fibroblasts, macrophages, mast cells, fat cells, and some elastic fibers.
• This prevents the folding of the membrane.

Articular capsule Histology:

• It consists of a dense collagenous membrane that seals the joint space and provides passive stability.
• It consists of increased local thickening in its walls and provides active stability from proprioceptive nerve endings in the capsule.
• The capsule is lined on its inner surface by a synovial membrane.
• The upper part of the capsule consists of fibrous and elastic tissue while the lower part consists of collagen fibers.
