Pituitary Gland
Pituitary Gland

A small, unpaired gland situated in the SELLA TURCICA. It is connected to the HYPOTHALAMUS by a short stalk.

Pituitary Gland, Anterior
Pituitary Gland, Anterior

The anterior glandular lobe of the pituitary gland, also known as the adenohypophysis. It secretes the ADENOHYPOPHYSEAL HORMONES that regulate vital functions such as GROWTH; METABOLISM; and REPRODUCTION.

Lactotrophs
Lactotrophs

Anterior pituitary cells that produce PROLACTIN.

Pituitary Gland, Intermediate
Pituitary Gland, Intermediate

The intermediate lobe of the pituitary gland. It shows considerable size variation among the species, small in humans, and large in amphibians and lower vertebrates. This lobe produces mainly MELANOCYTE-STIMULATING HORMONES and other peptides from post-translational processing of pro-opiomelanocortin (POMC).

Hypothalamo-Hypophyseal System
Hypothalamo-Hypophyseal System

A collection of NEURONS, tracts of NERVE FIBERS, endocrine tissue, and blood vessels in the HYPOTHALAMUS and the PITUITARY GLAND. This hypothalamo-hypophyseal portal circulation provides the mechanism for hypothalamic neuroendocrine (HYPOTHALAMIC HORMONES) regulation of pituitary function and the release of various PITUITARY HORMONES into the systemic circulation to maintain HOMEOSTASIS.

Median Eminence
Median Eminence

Raised area at the infundibular region of the HYPOTHALAMUS at the floor of the BRAIN, ventral to the THIRD VENTRICLE and adjacent to the ARCUATE NUCLEUS. It contains the terminals of hypothalamic neurons and the capillary network of hypophyseal portal system, thus serving as a neuroendocrine link between the brain and the PITUITARY GLAND.

Arcuate Nucleus
Arcuate Nucleus

A nucleus located in the middle hypothalamus in the most ventral part of the third ventricle near the entrance of the infundibular recess. Its small cells are in close contact with the ependyma.
