| bulb of posterior horn of lateral ventricle of brain | Bulb of posterior horn of lateral ventricle of the brain; a curved elevation on the inner wall of the posterior horn produced by the fibres of the forceps major of the corpus callosum as they bend backward into the occipital lobe. Synonym: bulb of posterior horn of lateral ventricle of brain. (05 Mar 2000) |

| ventral lateral nucleus of thalamus | 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) |
| medial vein of lateral ventricle | A vein that drains deep portions of the parietal and occipital lobes; it runs in the medial wall of the lateral ventricle to empty into the internal cerebral vein or the great cerebral vein. Synonym: vena ventriculi lateralis medialis, medial atrial vein, medial vein of lateral ventricle. (05 Mar 2000) |
