| neck of radius | The narrow part of the shaft just below the head. Synonym: collum radii. (05 Mar 2000) |

| styloid process of radius | A thick, pointed, palpable projection on the lateral side of the distal extremity of the radius. Synonym: processus styloideus radii. (05 Mar 2000) |
| 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) |
| tuberosity of radius | 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) |
| 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) |
| acute lower GI haemorrhage | <gastroenterology> Typical presentation: Sudden onset of brisk rectal bleeding without blood in gastric aspirate Diagnostic considerations: diverticulosis, angiodysplasia, ischemic colitis, inflammatory bowel disease (rarely), polyps are usually present, carcinoma causing a chronic bleed, haemorrhoids. (12 Dec 1998) |
| anterior surface of lower limb | The anterior surface of the inferior limb. Synonym: facies anterior membri inferioris. (05 Mar 2000) |
| arterial arch of lower eyelid | Formed by the medial palpebral artery which communicates with a branch of the lacrimal artery along the tarsal margin. Synonym: arcus palpebralis inferior. (05 Mar 2000) |
| bones of lower limb | These include the inferior limb girdle (hip bone) and the skeleton of the free inferior limb (femur, tibia, fibula, patella, tarsus, metatarsus, and bones of the toes). Synonym: ossa membri inferioris, bones of inferior limb. (05 Mar 2000) |
| regions of lower limb | The topographic divisions of the lower limb: gluteal, thigh (or femoral), knee, leg (or crural), ankle, and foot. Synonym: regiones membri inferioris, regions of inferior limb. (05 Mar 2000) |
