| proximal | <anatomy> Nearest to, closer to any point of reference, opposed to distal. (18 Nov 1997) |
|---|---|
| proximal border of nail | The proximal border of the nail entirely covered by the nail wall. Synonym: margo occultus unguis, occult border of nail. (05 Mar 2000) |
| proximal caries | Caries occurring in the proximal surface, either distal or mesial, of a tooth. (05 Mar 2000) |
| proximal centriole | The centriole that lies in a depression in the wall of the posterior portion of the nucleus of the developing spermatozoon. Synonym: anterior centriole. (05 Mar 2000) |
| proximal contact | Proximate contact, the area where the surfaces of two adjacent teeth in the same arch touch. Contact with reality, correctly interpreting external phenomena in relation to the norms of one's social or cultural milieu. Working contacts, working or occlusion; contact's of teeth made on the side of the occlusion toward which the mandible has been moved. Synonym: working bite, working occlusion. (05 Mar 2000) |
| proximal femoral focal deficiency | A congenital defect in which variable portions of the upper end of the femur are reduced or absent. (05 Mar 2000) |
| proximal interphalangeal joints | The synovial joint's between the proximal and middle phalanges of the fingers and of the toes. Synonym: PIP joints. (05 Mar 2000) |
| proximal radioulnar articulation | The pivot synovial joint between the head of the radius and the ring formed by the radial notch of the ulna and the annular ligament. Synonym: articulatio radioulnaris proximalis, proximal radioulnar articulation, superior radioulnar joint. (05 Mar 2000) |
| proximal small bowel disease | <radiology> Giardia, eosinophilic gastroenteritis, Zollinger-Ellison (12 Dec 1998) |
| proximal spiral septum | See: spiral septum. (05 Mar 2000) |
| proximal urethral sphincter | The complete collar of smooth muscle cells of the neck of the urinary bladder which extend distally to surround the preprostatic sportion of the male urethra. There is not a comparable structure in the neck of the femoral bladder; the internal urethral sphincter may exist to prevent reflux of semen into bladder. Synonym: annulus urethralis, internal urethral sphincter, musculus sphincter vesicae, preprostate urethral sphincter, proximal urethral sphincter, sphincter muscle of urinary bladder. (05 Mar 2000) |
| acromioclavicular joint | The joint formed by the acromion of the scapula and the acromial extremity of the clavicle. (12 Dec 1998) |
| ankle joint | The joint that is formed by the inferior articular and malleolar articular surfaces of the tibia, the malleolar articular surface of the fibula, and the medial malleolar, lateral malleolar, and superior surfaces of the talus. (12 Dec 1998) |
| anterior intraoccipital joint | Cartilaginous union in the newborn between the lateral and the basilar portions of the occipital bone. Synonym: synchondrosis intraoccipitalis anterior, anterior intraoccipital joint. (05 Mar 2000) |
| arthrodial joint | A synovial joint in which the opposing surfaces are nearly planes and in which there is only a slight, gliding motion, as in the intermetacarpal joints. Synonym: articulatio plana, arthrodia, arthrodial articulation, arthrodial joint, gliding joint. (05 Mar 2000) |
