| synovial cell | Fibrotoplast-like cells that form 1-6 epithelioid layers in the synovial membrane of joints; believed to contribute proteoglycans and hyaluronate to the synovial fluid. (05 Mar 2000) |
|---|---|
| synovial chondromatosis | Chondromatosis or osteocartilaginous nodules occurring in the synovial membrane of a joint. Synonym: synovial osteochondromatosis. (05 Mar 2000) |
| synovial crypt | A diverticulum of the synovial membrane of a joint. (05 Mar 2000) |
| synovial cyst | A nodular, tumourlike lesion in or about a tendon sheath or joint capsule, especially of the hands, wrists, or feet. It is not a true cyst as it lacks an epithelial wall, and it does not communicate with the underlying synovial space. The lesion represents a focal accumulation of mucin in the dermis of the dorsal aspect of the distal phalanges or, less often, other portions of the extremities. (12 Dec 1998) |
| synovial cyst, popliteal | A swelling in the space behind the knee (the popliteal space). The swelling is composed of a membrane-lined sac filled with synovial fluid that has escaped from the joint. Commonly called baker's cyst. (12 Dec 1998) |
| synovial fluid | <anatomy> Joint fluid, a viscous fluid which lubricates the joint. (27 Sep 1997) |
| synovial fold | A projection from the synovial membrane of a joint extending toward or between the two articular surfaces. Synonym: plica synovialis. (05 Mar 2000) |
| synovial frena | Fibrous bands that extend from the flexor tendons of the fingers and toes to the capsules of the interphalangeal joints and to the phalanges; they convey small vessels to the tendons. Synonym: vincula tendinum, synovial frena, synovial frenula. (05 Mar 2000) |
| synovial frenula | Fibrous bands that extend from the flexor tendons of the fingers and toes to the capsules of the interphalangeal joints and to the phalanges; they convey small vessels to the tendons. Synonym: vincula tendinum, synovial frena, synovial frenula. (05 Mar 2000) |
| synovial fringe | Small vascular processes given off from a synovial membrane. Synonym: villi synoviales, synovial fringe, synovial tufts. (05 Mar 2000) |
| synovial glands | <anatomy> Collections of adipose tissue in the hip, knee, and other joints, covered by synovial membrane, thought by Havers to be gland's secreting the synovia. Synonym: synovial glands. (05 Mar 2000) |
| synovial hernia | Protrusion of a fold of the stratum synoviale through a rent in the stratum fibrosum of a joint capsule. (05 Mar 2000) |
| synovial joint | A joint in which the opposing bony surfaces are covered with a layer of hyaline cartilage or fibrocartilage, there is a joint cavity containing synovial fluid, lined with synovial membrane and reinforced by a fibrous capsule and ligaments, and there is some degree of free movement possible. Synonym: articulatio synovialis, diarthrodial joint, diarthrosis, junctura synovialis, movable joint, perarticulation. (05 Mar 2000) |
| synovial ligament | <anatomy> One of the large synovial folds in a joint. (05 Mar 2000) |
| synovial lining | The lining of the joint. (12 Dec 1998) |
