| sternal notch | The V shaped notch at the top of the breastbone (sternum). (12 Dec 1998) |
|---|---|
| sternal part of diaphragm | The small slip on each side that arises from the inner surface of the xiphoid process and inserts on the central tendon. Synonym: pars sternalis diaphragmatis. (05 Mar 2000) |
| sternal plane | A plane indicated by the front surface of the sternum. Synonym: planum sternale. (05 Mar 2000) |
| sternal puncture | Removal of bone marrow from the manubrium by needle. (05 Mar 2000) |
| sternal synchondroses | The cartilaginous junctions between the body of the sternum and the manubrium, and the xiphoid process; in domestic animals, there may be several, e.g., synchondrosis manubriosternalis, synchondrosis intersternebralis, and synchondrosis xiphosternalis. Synonym: synchondroses sternales, sternal joints. (05 Mar 2000) |
| articular | <orthopaedics, rheumatology> Of or pertaining to a joint. Origin: L. Articularis (18 Nov 1997) |
| articular branches | Branches distributed to joints. Almost any vessel related to a joint will supply articular rami. Most joints receive articular branches from the intramuscular branches of the motor nerves innervating the muscles crossing the joint (see Hilton's law). at this printing, Nomina Anatomica, however, specifically recognises only the articular branches of the descending genicular artery, ramus articulares arteriae descendentis genicularis; supplying the knee joint. Synonym: rami articulares, joint branches. (05 Mar 2000) |
| articular capsule | A sac enclosing a joint, formed by an outer fibrous articular capsule and an inner synovial membrane. Synonym: capsula articularis, joint capsule. (05 Mar 2000) |
| articular cartilage | The cartilage covering the articular surfaces of the bones participating in a synovial joint. Synonym: cartilago articularis, arthrodial cartilage, diarthrodial cartilage, investing cartilage. (05 Mar 2000) |
| articular cavity | A joint cavity, the potential space bounded by the synovial membrane and articular cartilages of all synovial joints. Normally, the articular cavity contains only sufficient synovial fluid to lubricate the internal surfaces. Synonym: cavitas articularis, cavum articulare. (05 Mar 2000) |
| articular circumference of radius | The portion of the head of the radius that articulates with the radial notch of the ulna. Synonym: circumferentia articularis radii. (05 Mar 2000) |
| articular circumference of ulna | The portion of the head of the ulna that articulates with the ulnar notch of the radius. Synonym: circumferentia articularis ulnae. (05 Mar 2000) |
| articular corpuscles | Encapsulated nerve terminations within joint capsules. Synonym: corpuscula articularia. (05 Mar 2000) |
| articular crescent | A crescent-shaped intra-articular fibrocartilage found in certain joints. Synonym: meniscus articularis, articular crescent, intra-articular cartilage. (05 Mar 2000) |
| articular crests | Crests formed by the fusion of articular processes of all the sacral vertebrae. Synonym: articular crests, cristae sacrales intermediae. (05 Mar 2000) |
