Quick Facts

This structure lies medial to the internal capsule and subthalamus. It consists of anterior, intermediate, lateral, posterior and dorsal hypothalamic areas with their specific nuclei.

The adenohypophysis and hypothalamus form the hypothalamohypophysial portal system which secretes important endocrine hormones. It has afferent and efferent connections with the neurohypophysis, mesencephalon, limbic system and the cerebellum.

The hypothalamus is the center for feelings, instincts, motivational states and emotional reactions. It also plays an important role in regulating the internal environment of the body, especially that of body temperature, blood pressure and circadian rhythm.
