An intervertebral disc (British English), also spelled intervertebral disk (American English), lies between adjacent vertebrae in the vertebral column.Each disc forms a fibrocartilaginous joint (a symphysis), to allow slight movement of the vertebrae, to act as a ligament to hold the vertebrae together, and to function as a shock absorber for the spine.
Micrograph showing a fragment of an intervertebral disc demonstrating degenerative fibrocartilage with loss of nuclei and nests of chondrocytes, as seen in degenerative disc disease. HPS stain. Degeneration of fibrocartilage is seen in degenerative disc disease.
The triangular fibrocartilage disc (TFC) is an articular discus that lies on the pole of the distal ulna. It has a triangular shape and a biconcave body; the periphery is thicker than its center. It has a triangular shape and a biconcave body; the periphery is thicker than its center.
These include fibrocartilaginous and hyaline joints, which usually occur at the midline. Some examples of secondary cartilaginous joints in human anatomy would be the manubriosternal joint (between the manubrium and the body of the sternum), intervertebral discs, and the pubic symphysis. Articulating bones at a symphysis are covered with ...
The fibrocartilaginous disk is reinforced by a series of ligaments. These ligaments cling to the fibrocartilaginous disk to the point that fibers intermix with it. Two such ligaments are the superior pubic ligament and the inferior pubic ligament, which provide the most stability; the anterior and posterior ligaments are weaker.
The articular disc (or disk) is a thin, oval plate of fibrocartilage present in several joints which separates synovial cavities. This separation of the cavity space ...
The joint features a fibrocartilaginous articular disc, which completely divides the joint to form two articular compartments. [1] The disc acts to increase the range of movement of the joint. [ 2 ]
A meniscus (pl.: menisci or meniscuses) is a crescent-shaped fibrocartilaginous anatomical structure that, in contrast to an articular disc, only partly divides a joint cavity. [1] In humans, they are present in the knee, wrist, acromioclavicular, sternoclavicular, and temporomandibular joints; [2] in other animals they may be present in other ...
