The term “hypothalamus” has been derived from the Greek word that means “under chamber” as at that time it was a mystery understanding what does the hypothalamus secrete that controls the functioning of the entire body.
It is evident that it is the link between the nervous system and the endocrine system and therefore it is important to understand what does the hypothalamus secrete, that regulates the functioning of the pituitary gland.
If you want to understand it, it would be useful to gain knowledge on the anatomy and function of it. It is composed of various nuclei that secrete neurohormones.
The nuclei receive input in the form of stimulus from nerve endings present in the brain. These neurotransmitter signals are converted into hormonal secretions. Thus it would be important to know what does the hypothalamus secrete from various parts and how do these neurohormones control the functioning of it.
The corticotrophin releasing hormone is secreted by the parvocellular neurosecretory cells and it stimulates the pituitary gland to produce the adenocorticotropic hormone. It also secretes the Thyrotropin, dopamine or prolactin inhibiting hormone, growth releasing hormone, somatostatin or growth inhibiting hormone, gonadotropin releasing hormone, oxytocin and vasopressin.
