Question

List the hormones secreted by Hypothalamus.

Answer 1

Hint: Hypothalamus is the small portion of the brain, where it contains the different types of the nucleus, have a variety of functions, the main function of the hypothalamus is to connect the nervous system with endocrine system.

Complete answer:
This hypothalamus works as a neuroendocrine system, where it controls several glands in the body. It secrets the releasing factors or releasing hormones, which in turn they stimulate certain organs and body parts.

Hormone name	Nucleus name	Affects
Thyrotropin-releasing hormone	Parvocellular neurosecretory cells of the paraventricular nucleus	It stimulates the anterior pituitary to release the thyrotropin-releasing hormone.
Prolactin releasing hormone	Parvocellular neurosecretory cells of the para ventricular nucleus	It stimulates the prolactin to release the prolactin releasing hormone
Corticotropin releasing hormone	Parvocellular neuro secretory cells of the para ventricular nucleus	Adrenocorticotropic releasing hormone from the anterior pituitary
Dopamine	Dopamine releasing cells of arcuate nucleus	It releases dopamine which inhibits prolactin, released from anterior pituitary.
Growth hormone releasing hormone	Neuroendocrine nucleus of the arcuate nucleus	Release growth hormone from anterior pituitary
Gonadotropin releasing hormone	Neuroendocrine cells of preoptic area	It release the follicle stimulating hormone and luteinizing hormone from the anterior pituitary
Somatostatin	Neuroendocrine cells of pre ventricular nucleus	It releases from anterior pituitary where it inhibits the growth hormone and thyroid stimulating hormone.

Note: In hypothalamic neurohypophyseal axis, some hormones are released from posterior pituitary, they are oxytocin and vasopressin, oxytocin for childbirth and lactation, while vasopressin is to produce the concentrated urine, while reabsorbing water in the distal tubules of neurons of the kidneys.
