| articular cartilage n. The cartilage covering the articular surfaces of the bones forming a synovial joint. Also called arthrodial cartilage, diarthrodial cartilage, investing cartilage. |
articular cartilage
Etymology: L, articulare + cartilago
a type of hyaline connective tissue that covers the articulating surfaces of bones within synovial joints. See also cartilage.
cartilage,
n a derivative of connective tissue arising from the mesenchyme. Typical hyaline type is a flexible, rather elastic material with a semitransparent, glasslike appearance. Its intercellular substance is a complex protein (chondromucoid) through which is distributed a large network of connective tissue fibers.
cartilage, articular,
n a thin layer of hyaline cartilage located on the joint surfaces of some bones. Not usually found on articular surfaces of temporomandibular joints, which are covered with an avascular fibrous tissue.
n the cartilage containing a rounded articular protrusion, or condyle, present at bone joints. Condylar cartilage of the mandible is a common type.
cartilage, cricoid,
n the most inferior cartilage of the larynx.
cartilage, Meckel's,
n.pr the cartilaginous process in the embryo derived from the mesenchymal tissue of the mandibular process.

similar to an articular disk but is semicircular or C-shaped.
articular plate
the cartilaginous covering at the epiphysis of bones in arthrodial joints. Together with the growth cartilage comprises the joint cartilage.
articular rigidity
fixation of a joint, including arthrogryposis and ankylosis. May be caused by contracture of tendons, ligaments or muscles, by deformity of joint surfaces or by fusion of them.
