Also, tliere are deep cerebellar nuclei embedded within tlie white mailer, namely den¬tate nucleus, embolifonn nucleus, globose nucleus, and fasligial nucleus. The white matter of the two sides is connected by a thin lamina moncler of filters that are closely re¬lated to the fouith ventricle. The upper pan of litis lam¬ina forms the superior medullary velum and its inferior pan forms the inferior medullary velum. Both these take pan in forming lite roof (posterior boundary) of ihc fourth ventricle. The cerebellar peduncles connecting the cerebellum wilh midbrain, pons, and medulla arc al¬ready described in those moncler clothing sections.olencephalonthe dicnccphalon consists of thalamus, hypothalamus, subthalantus. And cpithalumus. The thulami lie on either side of tlie third vcntriele. Massa intermedia or intcrtlul- amic adltcsion councils the two thakuni.The hypothalamus lies around inferior aspect of die third ventriele and consists of the preoptic region ad¬joining the lamina tcrininalis. Supraoptic region above d>c optic chiasm. Inlundibukiuibcrul region consisting of tlie piluiury infundibulum. Tuber cinereum and the re¬gion above il. And mamillary or posterior region consist¬ing of the mamillary bodies and the region above it. Of these, the preoptic region is actually a derivative uf the telencephalon.The subthalamic or ventral thalamus Ik's behind and lateral U> Ihc h) pothalamus. Inferior!)' it is continuous with the upper ends of substantia nigra and red nucleus of the midbrain and laterally il is related lo the lowest pan of the moncler jacket internal capsule.The cpiihalamos consists of the pineal gland and hahcnular nuclei. The pineal gland lies anteroinferior to the splenmm of corpus callosum and vein of Gak-n/- Internal cerebral vein and posterosupcrior to Ihc tcctal plate/quadrigeminal cistern. Pineal masses elevate ihc vein of Galen/Internal cerebral veins and depress Ihe tcctal plate. The suprapineal recess of the third ventricle extends posteriorly immediately above moncler jackets the pineal gland. The quadrigcminal plate cistern lies posterior to the pineal gland and its anterior extension called the velum intcrpositutn lies above the pineal gland/internal cere¬bral vein and extends anteriorly below the corpus callo- sum/fomix. The tentorial apex arches above and behind tbe pineal gland and the course of fourth cranial nerves lies in close relationship. Tlie attachment of the pineal body to the posterior wall of moncler outlet the third ventricle is through a stalk that has moncler jacket sale two laminae, superior and inferior. The superior lamina is traversed by fibers of the habcnulai commissure and the inferior lamina by fibers of the posterior commissure.basal gangliathe caudate nucleus is a C-sliapcd mass of gray matter with a head abutting the lateral wall of ihc frontal bom of lateral ventricle and licsanterutncdial lo the lentiform nu¬cleus separated by tlie anterior limb of internal capsule, a body llial abuts ilie body of lateral ventricle, and a tail tlial continues antcroinfcriorly with tlie lentiform nucleus.
