A small gland that is located near the center of the brain. This gland secretes melatonin, and it may therefore be part of the body's sleep-regulation apparatus. Also known as pineal body.

Gland at the base of the brain controlling melatonin levels.

A gland located in the middle of the brain, between the brain's two hemispheres, that produces melatonin in response to declining light.

gland in the brain secreting the hormone melatonin.

The pineal gland is a hormone-producing gland located within the brain.

Definition: (Epiphysis, conarium) Small, flat gland located in the interbrain (diencephalon).

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.

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.

 An endocrine organ found in the brain. In some animals, it seems to serve as a light-influenced biological clock. 

A tiny organ in the cerebrum that produces melatonin. Also called pineal body and pineal organ.

Also called pineal body or epiphysis, it is a pea-sized endocrine gland in the middle of the brain. The pineal produces melatonin, regulated in circadian rhythm, and plays a role in sexual development, hibernation and metabolism. Rene Descartes famously located the "seat of the soul" to the pineal gland. Population coding

an endocrine gland that secretes melatonin, which is thought to regulate daily and annual rhythms, such as sleep and reproductive cycles

A tiny organ in the cerebrum that produces melatonin. Also called pineal body and pineal organ.

(pin-ee-ul) A small endocrine gland on the dorsal surface of the vertebrate forebrain; secretes the hormone melatonin, which regulates body functions related to seasonal day length.

A gland located in the brain that secretes the hormone melatonin.

A secretory gland in the brain midline; the source of melatonin release. See Figures 2.12, 5.1; Table 5.2.
