Hypersecretion of the population from the anterior pituitary gland causes the condition of galactorrhea.
Prolactin is another name is called luteotropin and its main function is to enable mammals mostly female to produce milk. The pituitary gland secretes it in response to mating, estrogen treatment, ovulation, nursing and eating.
The pituitary gland is attached to the hypothalamus by a short stalk. The pituitary gland has two major parts.
(i) An anterior lobe
(ii) Posterior lobe.
The pituitary gland is controlled by hormones and neurons that comes in the hypothalamus where it acts as a link between brain and endocrine system, and hypothalamus is the endocrine gland itself. Hypothalamus has neurons which regulate secretion of anterior lobe hormones by secreting inhibit and releasing hormones. Every hormone produced by anterior lobe has a releasing hormone.
Prolactin and growth hormones have inhibiting hormone. Releasing hormone helps in stimulating production and it releases hormones from the anterior lobe.
