| syndrome, thrombocytopenia-absent radius | See Syndrome, TAR. (12 Dec 1998) |
| interosseous border of radius | The ridge along the medial side of the radius to which is attached the interosseous membrane. Synonym: margo interosseus radii. (05 Mar 2000) |
| orbicular ligament of radius | The ligament that encircles and holds the head of the radius in the radial notch of the ulna, forming the proximal radioulnar joint and enabling pronation/supination of forearm; receives the radial collateral ligament of the elbow. Synonym: ligamentum annulare radii, ligamentum orbiculare radii, orbicular ligament of radius. (05 Mar 2000) |
| thrombocytopenia-absent radius syndrome | <syndrome> Tar stands for thrombocytopenia (low blood platelets) and aplasia (absence) of the radius (the long bone on the thumb-side of the forearm), features characterizing this syndrome. There is phocomelia (flipper-limb) with the thumbs always present. The fibula (the smaller bone in the lower leg) is often absent. The risk of bleeding from too few platelets is high in early infancy but lessens with age. The condition is inherited in an autosomal recessive trait with one gene (on a non-sex chromosome) coming from each parent to the tar child. Alternative names include thrombocytopenia-absent radius syndrome, radial aplasia-thrombocytopenia syndrome, and tetraphocomelia-thrombocytopenia syndrome. (12 Dec 1998) |
| effective collision radius | <radiobiology> Effective size of a particle equal to the square root of (cross-section/pi). Determines the effective range of interaction of the particle. (09 Oct 1997) |
| finite larmor radius | (FLR) In many plasma theories the size of the Larmor radius (or gyroradius) is assumed to be negligibly small, or infinitesimal. Different effects occur when the size of the Larmor radius is finite and needs to be considered. (09 Oct 1997) |
| larmor radius | <radiobiology> The radius of the path of a charged particle moving in a magnetic field (and transverse to the field lines). Synonym: gyroradius, cyclotron radius. (09 Oct 1997) |
| bicipital tuberosity | An oval projection from the medial surface of the radius just distal to the neck, giving attachment on its posterior half to the tendon of the biceps. Synonym: tuberositas radii, bicipital tuberosity, tuber radii, tuberosity of radius. (05 Mar 2000) |
| calcaneal tuberosity | The posterior extremity of the calcaneus, or os calcis, forming the projection of the heel. Synonym: tuber calcanei, calcaneal tuber, tuber calcis. (05 Mar 2000) |
| radial tuberosity | An oval projection from the medial surface of the radius just distal to the neck, giving attachment on its posterior half to the tendon of the biceps. Synonym: tuberositas radii, bicipital tuberosity, tuber radii, tuberosity of radius. (05 Mar 2000) |
| masseteric tuberosity | A roughened surface on the external aspect of the angle of the mandible, giving attachment to fibres of the masseter muscle. Synonym: tuberositas masseterica. (05 Mar 2000) |
| maxillary tuberosity | The bulging lower extremity of the posterior surface of the body of the maxilla, behind the root of the last molar tooth. Synonym: tuber maxillae, eminentia maxillae, maxillary eminence. (05 Mar 2000) |
| medial femoral tuberosity | The epicondylus located proximal to the medial condyle. Synonym: epicondylus medialis ossis femoris, medial femoral tuberosity. (05 Mar 2000) |
| medial process of calcaneal tuberosity | The medial projection from the posterior part of the calcaneus. Synonym: processus medialis tuberis calcanei. (05 Mar 2000) |
