| lateral cerebral fissure | The deepest and most prominent of the cortical fissures, extending from the anterior perforated substance first laterally at the deep incisure between the frontal and temporal lobes, then back and slightly upward over the lateral aspect of the cerebral hemisphere, with the superior temporal gyrus as its lower bank, the insula forming its greatly expanded floor. Two short side branches, the ramus anterior and ramus ascendens, divide the inferior frontal gyrus into an orbital part, triangular part, and opercular part. Synonym: sulcus lateralis cerebri, fissura cerebri lateralis, lateral cerebral fissure, sylvian fissure, fissure of Sylvius. (05 Mar 2000) |

| lateral cerebral fossa | 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) |

Two short side branches, the ramus anterior and ramus ascendens, divide the inferior frontal gyrus into an orbital part, triangular part, and opercular part. Synonym: sulcus lateralis cerebri, fissura cerebri lateralis, lateral cerebral fissure, sylvian fissure, fissure of Sylvius. (05 Mar 2000) |
| lateral cervical nuclei | Diffusely arranged nucleus located in the dorsal portions of the lateral funiculus in about cervical levels C1-C3; synaptic station for the spinocervicothalamic tract. (05 Mar 2000) |
| lateral circumflex artery of thigh | <anatomy, artery> Origin, profunda femoris; distribution, hip joint, thigh muscles; anastomoses, medial circumflex femoral, inferior gluteal, superior gluteal.

| lateral circumflex femoral veins | The veins that accompany the lateral circumflex femoral artery, usually terminating in the femoral vein. Synonym: venae circumflexae femoris laterales. (05 Mar 2000) |
| lateral collateral | A strong ligament which connects the femur to the tibia, stabilising the outer aspect of the knee joint. (27 Sep 1997) |
| lateral collateral ligament of ankle | The calcaneofibular ligament, anterior talofibular ligament, and posterior talofibular ligament together maintaining the integrity of the lateral aspect of the talocrural joint. Synonym: fibular collateral ligament of ankle. (05 Mar 2000) |
| lateral column | A slight protrusion of the gray matter of the spinal cord into the lateral funiculus of either side, especially marked in the thoracic region where it encloses preganglionic motor neurons of the sympathetic division of the autonomic nervous system; it corresponds to the lateral horn appearing in transverse sections of the spinal cord. See: gray columns. Synonym: columna lateralis, lateral column of spinal cord. (05 Mar 2000) |
