Hyptothalamus

About

The Hypothalamus is a portion of the brain that contains a number of small nuclei with a variety of functions. One of the most important functions of the hypothalamus is to link the nervous system to the endocrine system via the pituitary gland (hypophysis).

The hypothalamus is located below the thalamus, just above the brain-stem. In the terminology of neuroanatomy, it forms the ventral part of the diencephalon. All vertebrate brains contain a hypothalamus. In humans, it is roughly the size of an almond.

The hypothalamus is responsible for certain metabolic processes and other activities of the autonomic nervous system. It synthesizes and secretes certain neurohormones, often called
hypothalamic-releasing hormones, and these in turn stimulate or inhibit the secretion of pituitary hormones.
The hypothalamus controls body temperature, hunger, thirst,[1] fatigue, sleep, and circadian cycles.
