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 nameNucleus nameAffects
Thyrotropin-releasing hormoneParvocellular neurosecretory cells of the paraventricular nucleusIt stimulates the anterior pituitary to release the thyrotropin-releasing hormone.
Prolactin releasing hormoneParvocellular neurosecretory cells of the para ventricular nucleusIt stimulates the prolactin to release the prolactin releasing hormone
Corticotropin releasing hormoneParvocellular neuro secretory cells of the para ventricular nucleusAdrenocorticotropic releasing hormone from the anterior pituitary
DopamineDopamine releasing cells of arcuate nucleusIt releases dopamine which inhibits prolactin, released from anterior pituitary.
Growth hormone releasing hormoneNeuroendocrine nucleus of the arcuate nucleusRelease growth hormone from anterior pituitary
Gonadotropin releasing hormoneNeuroendocrine cells of preoptic areaIt release the follicle stimulating hormone and luteinizing hormone from the anterior pituitary
SomatostatinNeuroendocrine cells of pre ventricular nucleusIt 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.
