| ulnar margin of forearm | An imaginary line extrapolated from the medial epicondyle of the humerus to the styloid process of the ulna, forming a border between the anterior and posterior surfaces. Synonym: margo medialis antebrachii, margo ulnaris antebrachii, ulnar margin of forearm. (05 Mar 2000) |
|---|---|
| ulnar nerve | <anatomy, nerve> A major nerve of the upper extremity. In humans, the fibres of the ulnar nerve originate in the lower cervical and upper thoracic spinal cord (usually c7 to t1), travel via the medial cord of the brachial plexus, and supply sensory and motor innervation to parts of the hand and forearm. (12 Dec 1998) |
| ulnar nerve compression syndrome | <syndrome> A condition caused by compression or entrapment of the ulnar nerve. It may involve both sensory and motor problems and most often results from compression or entrapment of the ulnar nerve at the elbow (cubital tunnel syndrome). Compression of the nerve may occur during normal activities or as a complication of general anaesthesia. (12 Dec 1998) |
| ulnar notch | The concave surface on the medial side of the distal end of the radius which articulates with the head of the ulna. Synonym: incisura ulnaris. (05 Mar 2000) |
| ulnar reflex | Pronation and adduction of the hand caused by tapping the styloid process of the ulna. Synonym: pronator reflex. (05 Mar 2000) |
| ulnar styloid erosions | <radiology> Seen in rheumatoid arthritis, related to: triangular fibrocartilage, prestyloid recess (of joint space), extensor carpi ulnaris tendon (12 Dec 1998) |
| ulnar variance | <radiology> Ulna minus variance ulna shorter than radius increased frequency of avascular necrosis of lunate associated with DISI, ulna plus variance ulna longer than radius increased stress on triangular fibrocartilage (12 Dec 1998) |
| ulnar veins | Venae comitantes of the ulnar artery, continuing from those of the supericial palmar arch and joining with those of the radial artery to form the brachial veins in the cubital fossa. Synonym: venae ulnares. (05 Mar 2000) |
| lateral collateral | A strong ligament which connects the femur to the tibia, stabilising the outer aspect of the knee joint. (27 Sep 1997) |
| 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 distal radioulnar joint | 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) |
