The main function of hypothalamus

Explanation

Hypothalamus is located below the thalamus. It connects the neural and endocrine systems, as it closely tied to the pituitary gland. It responds to the sensory impulses received from different-receptors by sending out appropriate neural or endocrine signals.
The hypothalamus is the master control centre of the endocrine system, as it contains several group of neuro secretary cells called nuclei, which produce hormones called neuro hormones, These hormones directly control the pituitary gland which in turn secrete hormone that regulate the growth and functioning of other endocrine glands.
For example : The two types of hormones produced by the hypothalamus are :
I) Releasing hormones : Which stimulates the secretions of pituitary hormones.
Eg: 1) Thyrotropin releasing hormone-acts on anterior pituitary to release thyroid stimulating hormone.
2) Growth hormone releasing hormone-stimulate the release of growth hormone. 2) Inhibiting hormones : Which inhibits the secretion of pituitary hormones.
Eg: 1) Growth hormone release inhibiting hormone - which inhibit the release of growth hormone from anterior pituitary.
2) Prolactin release inhibiting hormone - Inhibit the release of prolactin from anterior pituitary.
