| primary lateral sclerosis | Considered by many to be a subgroup of motor neuron disease; a slowly progressive degenerative disorder of the motor neurons of the cerebral cortex, resulting in widespread weakness on an upper motor neuron basis; spasticity, hyperreflexia, and Babinski signs are present, but not fasciculation potentials, nor any electrodiagnostic evidence of a lower motor neuron lesion. Synonym: lateral spinal sclerosis. (05 Mar 2000) |
| prominence of lateral saemicircular canal | The slight bulge in the medial wall of the epitympanic recess caused by the proximity of the lateral saemicircular canal. Synonym: prominentia canalis saemicircularis lateralis. (05 Mar 2000) |
| X-ray, lateral | An X-ray picture taken from the side. (12 Dec 1998) |
| hypothalamic area, lateral | An area in the middle hypothalamus continuous rostrally with the lateral preoptic area and caudally with the tegmentum mesencephali. It contains the tuberomammillary and lateral tuberal nuclei. (12 Dec 1998) |
| subcutaneous bursa of lateral malleolus | lateral malleolar subcutaneous bursa |
| nucleus of lateral geniculate body | Nucleus of the thalamus characterised by six layers of cells, two parvicellular, four magnocellular, alternating with thin layers of fibres; receives bilateral visual input, projects to calcarine cortex. (05 Mar 2000) |
| nucleus of lateral lemniscus | A substantial cell mass embedded in the lateral lemniscus, immediately below the latter's entry into the inferior colliculus; the nucleus represents a synaptic way-station for part of the fibres of the lateral lemniscus. Synonym: nucleus lemnisci lateralis. (05 Mar 2000) |
| superior lateral genicular artery | <anatomy, artery> Origin, popliteal; distribution, knee joint; anastomoses, lateral circumflex femoral, third perforating, anterior tibial recurrent, lateral inferior genicular, i.e., the articular vascular network of the knee. Synonym: arteria genus superior lateralis, lateral superior genicular artery. (05 Mar 2000) |
| descending branch of lateral circumflex femoral artery | <anatomy, artery> A major branch of the lateral circumflex femoral artery accompanying the nerve to the vastus lateralis muscle along the anterior border of that muscle and deep to the rectus femoris muscle, supplying both muscles. Anastomosis: with lateral superior genicular artery, i.e., it contributes to the articular network of the knee. Synonym: ramus descendens arteriae circumflexae femoris lateralis. (05 Mar 2000) |
| inferior horn of lateral ventricle | The part of the lateral ventricle extending downward and forward into the medial part of the temporal lobe. See: lateral ventricle. Synonym: cornu inferius ventriculi lateralis, temporal horn. (05 Mar 2000) |
| inferior lateral genicular artery | <anatomy, artery> Origin, popliteal; distribution, knee joint; anastomoses, lateral superior genicular and anterior tibial recurrent (and posterior); i.e., articular vascular network of knee. Synonym: arteria genus inferior lateralis, lateral inferior genicular artery. (05 Mar 2000) |
| trigone of lateral ventricle | A triangular prominence of the floor of the lateral ventricle at the transition between occipital and temporal horn, continuous rostrally with the collateral eminence and, like the latter, caused by the deep penetration of the collateral sulcus from the ventral surface of the temporal lobe. Synonym: trigonum collaterale, trigone of lateral ventricle, trigonum ventriculi, ventricular trigone. (05 Mar 2000) |
| film, lateral | An X-ray picture taken from the side. (12 Dec 1998) |
| lacertus of lateral rectus muscle | <anatomy> The part of the tendon of origin of the lateral rectus muscle attaching to the greater wing of the sphenoid bone, lateral to the common tendinous ring; often incorrectly equated to the lateral check ligament of the eyeball. Synonym: lacertus musculi recti lateralis. (05 Mar 2000) |
