| nucleus lateralis thalami | The largest of the major subdivisions of the thalamus; the composite lateral nucleus includes, from before backward, the nucleus lateralis anterior or dorsalis, nucleus lateralis intermedius, nucleus lateralis posterior, and pulvinar; together, these cell groups form most of the free dorsal surface of the posterior half of the thalamus and project to a very large region of parietal, occipitoparietal, and temporal cortex; its afferent connections are largely obscure, but the nucleus lateralis posterior and the pulvinar receive a projection from the superior colliculus. Synonym: nucleus lateralis thalami. (05 Mar 2000) |

| nucleus lemnisci lateralis | 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) |
| nucleus preopticus lateralis | A vaguely defined group of nerve cells in the lateral zone of the preoptic region. Synonym: nucleus preopticus lateralis. (05 Mar 2000) |
| nucleus ventralis lateralis | The composite middle third of the ventral nucleus receiving in its various parts distinctive projections from the contralateral half of the cerebellum (by way of the superior cerebellar peduncle) and the ipsilateral globus pallidus; nearly all parts of the nucleus projects to the motor cortex. Synonym: nucleus ventralis intermedius thalami, nucleus ventralis lateralis, ventral lateral nucleus of thalamus. (05 Mar 2000) |
| onychia lateralis | <dermatology> Inflammation involving the folds of tissue surrounding the nail. Synonym: perionychia. Origin: Gr. Onyx = nail (18 Nov 1997) |
| tractus corticospinalis lateralis | Those fibres of the pyramidal tract that cross to the opposite side in the pyramidal decussation and descend in the dorsal half of the lateral funiculus of the spinal cord; they are distributed throughout the length of the spinal cord to interneurons of the zona intermedia of the spinal gray matter. See: pyramidal tract. Synonym: tractus corticospinalis lateralis, tractus pyramidalis lateralis, crossed pyramidal tract, fasciculus corticospinalis lateralis, fasciculus pyramidalis lateralis, lateral corticospinal tract, lateral pyramidal fasciculus.

| epicondylus lateralis humeri | The epicondylus situated at the lateral side of the distal end of the bone. Synonym: epicondylus lateralis humeri. (05 Mar 2000) |
| epicondylus lateralis ossis femoris | The epicondylus located proximal to the lateral condyle. Synonym: epicondylus lateralis ossis femoris, lateral femoral tuberosity. (05 Mar 2000) |
| facies anterior lateralis corporis humeri | The surface of the humerus lateral to the intertubercular groove. Synonym: facies anterior lateralis corporis humeri, facies anterolateralis corporis humeri. (05 Mar 2000) |
| facies lateralis | The surface of a part of the body that faces away from the midline. The NA recognises a lateral surface on the following structures: fibula; ovary; radius; testis; tibia; zygomatic bone. Synonym: facies lateralis. (05 Mar 2000) |
| facies lateralis brachii | The lateral surface of the arm. Synonym: facies lateralis brachii. (05 Mar 2000) |
