Pineal Gland
Pineal Gland

A light-sensitive neuroendocrine organ attached to the roof of the THIRD VENTRICLE of the brain. The pineal gland secretes MELATONIN, other biogenic amines, and neuropeptides.

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).

Diencephalon
Diencephalon

The paired caudal parts of the prosencephalon from which the THALAMUS; HYPOTHALAMUS; EPITHALAMUS; and SUBTHALAMUS are derived.

Hypothalamus
Hypothalamus

Ventral part of the diencephalon extending from the region of the optic chiasm to the caudal border of the mammillary bodies and forming the inferior and lateral walls of the third ventricle.

Preoptic Area
Preoptic Area

Region of hypothalamus between the anterior commissure and optic chiasm.

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.

Habenula
Habenula

A small protuberance at the dorsal, posterior corner of the wall of the third ventricle, adjacent to the dorsal thalamus and pineal body. It contains the habenular nuclei and is a major part of the epithalamus. (From Lockard, Desk Reference for Neuroscience, 2nd ed, p121)

Thalamus
Thalamus

Paired bodies containing mostly gray substance and forming part of the lateral wall of the third ventricle of the brain. The thalamus represents the major portion of the diencephalon and is commonly divided into cellular aggregates known as nuclear groups.

Geniculate Bodies
Geniculate Bodies

Part of the diencephalon inferior to the caudal end of the dorsal thalamus. Includes the lateral geniculate body which relays visual impulses from the optic tract to the calcarine cortex, and the medial geniculate body which relays auditory impulses from the lateral lemniscus to the auditory cortex.
