Comment: The major nuclei in the tuberal zone include the
dorsomedial nucleus, ventromedial nucleus, periventricular nucleus,
arcuate nucleus, periarcuate area (beta endorphin cells), tuberal
nuclei, dorsal hypothalamic area, and lateral hypothalamic area.
These neurons regulate a variety of visceral functions (feeding,
drinking, reproductive behavior) and neurohormonal activities of the
anterior pituitary gland. The median eminence extends from this
region; axons from releasing-factor and inhibitory-factor neurons
that control the release of anterior pituitary hormones end at the
contact zone of the median eminence and release their factors into
the hypophysial portal system, a local vascular system that bathes
the cells of the anterior pituitary with high concentrations of those
factors.
