Median eminence

Median eminence ( eminentia from the Latin " Outstanding ", " Excellent ", from the Latin median "in the middle lying " ) refers to a Neurohämalorgan in the form of a highly vascular region in the area of ​​the pituitary stalk at the base of the hypothalamus, which is particularly characterized differentiated ependymal the Tanycyten, and builds from extending to posterior pituitary axons.

On special capillary loops of the median eminence axons of neuropeptide -producing neurons of the hypothalamus that release here via special contact structures, neurovascular junctures, the neuropeptides in the blood. The neuropeptides accessed via the pituitary portal venous system the glandular portion of the pituitary gland, the anterior pituitary, and are effective here as releasing or Inhibiting hormones.

The median eminence is the most important interface between the nervous and endocrine systems.
