| distal ileitis | A subacute chronic enteritis, of unknown cause, involving the terminal ileum and less frequently other parts of the gastrointestinal tract; characterised by patchy deep ulcers that may cause fistulas, and narrowing and thickening of the bowel by fibrosis and lymphocytic infiltration, with noncaseating tuberculoid granulomas that also may be found in regional lymph nodes; symptoms include fever, diarrhoea, cramping abdominal pain, and weight loss. Synonym: chronic cicatrizing enteritis, Crohn's disease, distal ileitis, regional ileitis, terminal ileitis, granulomatous enteritis. (05 Mar 2000) |

| distal occlusion | A tooth occluding in a position distal to normal. Synonym: disto-occlusion, postnormal occlusion, retrusive occlusion. Synonym: distoclusion. (05 Mar 2000) |
| distal part of anterior lobe of hypophysis | The larger part of the adenohypophysis composed of cords of epithelial cells individually specialised to secrete various tropic hormones that exert their effect on several target organs in the body. The secretory activity of these cells is under the control of either releasing or inhibiting factors elaborated by hypothalamic neurons and transported to the adenohypophysis by the hypothalamo-hypophysial portal system. Synonym: pars distalis. (05 Mar 2000) |
| distal radioulnar articulation | The pivot synovial joint between the head of the ulna and the ulnar notch on the radius; an articular disk passes across the distal part of the joint. Synonym: articulatio radioulnaris distalis, distal radioulnar articulation, inferior radioulnar joint. (05 Mar 2000) |
| distal spiral septum | See: spiral septum. (05 Mar 2000) |
| distal splenorenal shunt | Anastomosis of the splenic end of the divided splenic vein to the left renal vein. Synonym: distal splenorenal shunt. (05 Mar 2000) |
| distal surface of tooth | The contact surface of a tooth that is directed away from the median plane of the dental arch; opposite to the mesial surface of a tooth. Synonym: facies distalis dentis. (05 Mar 2000) |
| tuberosity of distal phalanx | A roughened raised surface of horseshoe shape on the palmar surface of the distal end of the terminal or ungual phalanx of each finger and toe, which serves to support the pulp of the digit. Synonym: tuberositas phalangis distalis, tuberositas unguicularis, ungual tuberosity. (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) |
| articular disc of acromioclavicular joint | The articular disk of fibrocartilage usually found between the acromial end of the clavicle and the medial border of the acromion. Synonym: discus articularis acromioclavicularis, acromioclavicular disk, Weitbrecht's cartilage. (05 Mar 2000) |
| articular disc of sternoclavicular joint | The fibrocartilaginous disk that subdivides the sternoclavicular joint into two cavities. Synonym: discus articularis sternoclavicularis, sternoclavicular disk, sternoclavicular articular disk. (05 Mar 2000) |
| articular disc of temporomandibular joint | The fibrocartilaginous plate that separates the joint into upper and lower cavities. Synonym: discus articularis temporomandibularis, mandibular disk, temporomandibular articular disk. (05 Mar 2000) |
