| 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) |
| superficial branch of the lateral plantar nerve | <anatomy, nerve> Mostly cutaneous branch to skin of small and lateral half of fourth toes and lateral side of sole of foot, but also supplies the flexor digiti minimi brevis muscle and the most lateral dorsal and plantar interosseous muscles. Synonym: ramus superficialis nervi plantaris lateralis. (05 Mar 2000) |
| superior lateral brachial cutaneous nerve | <anatomy, nerve> The terminal branch of the axillary nerve supplying the skin over the lower portion of the deltoid and for a distance below its insertion. Synonym: nervus cutaneus brachii lateralis superior, upper lateral cutaneous nerve of arm. (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) |
| deep branch of the lateral plantar nerve | <anatomy, nerve> Motor branch of lateral plantar nerve supplying lumbricals 2-4, plantar and dorsal interossei, and the adductor hallucis muscles. Synonym: ramus profundus nervi plantaris lateralis. (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) |
