| fossa lateralis cerebri | The deep depression of the basal surface of the forebrain that corresponds in position to the anterior perforated substance. Bounded medially by the optic tract and rostrally by the orbital surface of the frontal lobe, it extends laterally around the overhanging pole of the temporal lobe into the Sylvian fissure (sulcus lateralis). Synonym: fossa lateralis cerebri, fossa of Sylvius, lateral fossa of brain, vallecula sylvii. (05 Mar 2000) |

| fossa malleoli lateralis | A large rough depression on the medial aspect of the lower end of the fibula just behind the articular facet for the talus giving attachment to the posterior talofibular and the transverse tibiofibular ligaments. Synonym: fossa malleoli lateralis, digital fossa, fossa malleoli fibulae. (05 Mar 2000) |
| lateralis | Synonym: lateral, lateral, lateral. Origin: L. (05 Mar 2000) |
| lemniscus lateralis | A bundle of ascending fibres that originate from the cochlear and auditory relay nuclei of the rhombencephalon, enter the trapezoid body, a transverse fibre stratum in which about half their number decussate, and from here turn rostrally along the lateral side of the spinothalamic tract; in the midbrain, it arches dorsally and enters the inferior colliculus in which all of its fibres terminate; the auditory pathway is transsynaptically extended from here by the brachium of the inferior colliculus to the medial geniculate body of the thalamus, from which in turn the auditory radiation leads to the auditory cortex; intercalated in the trapezoid body and along the ascending trajectory of the lemniscus are several cell groups in which part of the fibres synapse. Synonym: lemniscus lateralis, acoustic lemniscus, auditory lemniscus, auditory tract, lateral fillet. (05 Mar 2000) |
| funiculus lateralis | The lateral white column of the spinal cord between the lines of exit and entrance of the anterior and posterior nerve roots. Synonym: funiculus lateralis, anterolateral column of spinal cord, lateral funiculus of spinal cord. (05 Mar 2000) |
| ligamentum malleoli lateralis | See: anterior tibiofibular ligament, posterior tibiofibular ligament. (05 Mar 2000) |
| ligamentum menisci lateralis | <anatomy> The band that passes posterior to the posterior cruciate ligament extending between the medial condyle of the femur and the posterior crus of the lateral meniscus. Synonym: ligamentum meniscofemorale posterius, ligamentum cruciatum tertium genus, ligamentum menisci lateralis, Wrisberg's ligament. (05 Mar 2000) |
