| cyst, synovial, of the popliteal space | 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) |

| sarcoma, synovial | A malignant neoplasm arising from tenosynovial tissue of the joints and in synovial cells of tendons and bursae. The legs are the most common site, but the tumour can occur in the abdominal wall and other trunk muscles. There are two recognised types: the monophasic (characterised by sheaths of monotonous spindle cells) and the biphasic (characterised by slit-like spaces or clefts within the tumour, lined by cuboidal or tall columnar epithelial cells). These sarcomas occur most commonly in the second and fourth decades of life. (12 Dec 1998) |
| synovial | <anatomy> Of pertaining to or secreting synovia. Origin: L. Synovialis (18 Nov 1997) |
| 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) |
