Synonym: rete articulare cubiti. (05 Mar 2000) |
| articular vascular network of knee | An arterial network over the front and sides of the knee, formed by branches of the descending genicular artery, of the five genicular arteries from the popliteal, of the anterior tibial recurrent, and of the fibular circumflex branch of the posterior tibial. Synonym: rete articulare genus. (05 Mar 2000) |
| radioulnar articular disk | The disk that holds together the distal ends of the radius and ulna; it is attached by its apex to a depression between the styloid process and distal surface of the head of the ulna, and by its base to the ridge separating the ulnar notch from the carpal surface of the radius. Synonym: discus articularis radioulnaris, radioulnar disk, radioulnar articular disk, triangular cartilage, triangular disk of wrist, triquetrous cartilage. (05 Mar 2000) |
| range of motion, articular | Range through which a joint can be extended and flexed. This is frequently assessed following surgery of the joint. (12 Dec 1998) |
| retinaculum of articular capsule of hip | One of several longitudinal folds of the articular capsule of the hip joint reflected onto the femoral neck deep to which the retinacular branches of the medial femoral circumflex artery pass to reach the femoral head. Synonym: retinaculum capsulae articularis coxae, Weitbrecht's fibres. (05 Mar 2000) |
| cricoarytenoid articular capsule | The capsule enclosing the joint between the arytenoid and cricoid cartilages. Synonym: capsula articularis cricoarytenoidea. (05 Mar 2000) |
| cricothyroid articular capsule | The capsule enclosing the cricothyroid joint. Synonym: capsula articularis cricothyroidea. (05 Mar 2000) |
| sternoclavicular articular disk | The fibrocartilaginous disk that subdivides the sternoclavicular joint into two cavities. Synonym: discus articularis sternoclavicularis, sternoclavicular disk, sternoclavicular articular disk. (05 Mar 2000) |
| dislocation of articular processes | Complete dislocation of one or both articular processes, usually with overriding of the inferior articular process of the vertebra above into a position anterior to the superior articular process of the vertebra below. Synonym: locked facets. (05 Mar 2000) |
| inferior articular facet of atlas | One of two concave surfaces on the lateral masses of the atlas that articulate with corresponding surfaces on the axis. Synonym: facies articularis inferior atlantis, fovea articularis inferior atlantis, inferior articular pit of atlas. (05 Mar 2000) |
| inferior articular pit of atlas | One of two concave surfaces on the lateral masses of the atlas that articulate with corresponding surfaces on the axis. Synonym: facies articularis inferior atlantis, fovea articularis inferior atlantis, inferior articular pit of atlas. (05 Mar 2000) |
| intra-articular | Within the cavity of a joint. Origin: intra-+ L. Articulus, joint (05 Mar 2000) |
| intra-articular cartilage | A plate or ring of fibrocartilage attached to the joint capsule and separating the articular surfaces of the bones for a varying distance, sometimes completely; it serves to adapt two articular surfaces that are not entirely congruent. Synonym: discus articularis, articular disk, fibrocartilago interarticularis, fibroplate, interarticular fibrocartilage, intra-articular cartilage. (05 Mar 2000) |
