Archivo: Schematic representation of the hypothalamic nuclei

Descripción: A schematic representation of the hypothalamic nuclei and the distribution of tanycytes over the wall of the third ventricle (III-V). (A) Coronal view of the approximate location of the hypothalamic nuclei and tanycytes. Ciliated ependymocytes (ep) line the dorsal wall of the III-V. The α1d-tanycytes (α1d) and α1v-tanycytes (α1v) have long projections that make contact with the neurons of the VMN. α2-tancycytes (α2) have projections to the AN and blood vessels. In a more ventral section of the III-V, the β1d-tanycytes (β1d) and β1v-tanycytes (β1v) make projections to the AN, making contact with orexigenic and anorexigenic neurons and blood vessels. In the floor of the III-V, the β2la-tanycytes (β2la) and β2me-tanycytes (β2me) are joined by tight junctions forming part of the median eminence (ME)-cerebrospinal fluid (CSF) barrier, and their projections make contact with the fenestrated blood vessels of the ME. (B) Sagittal view of the distribution of the hypothalamic nuclei. Ep: ependymocytes; AN: arcuate nucleus; VMN: ventromedial nucleus; DMN: dorsomedial nucleus; PVN: periventricular nucleus; DHA: dorsal hypothalamic area; PFA: perifornical area; LHA: lateral hypothalamic area; SCN: suprachiasmatic nucleus; SON: supraoptic nucleus; POA: preoptic area; MB: mammillary bodies; ME: median eminence; III-V: third ventricle.
