The pituitary gland, or hypophysis, is an <span>endocrine gland that consists of anterior pituitary (or adenohypophysis) and posterior pituitary (or neurohypophysis). Adenohypophysis regulates several physiological processes (including stress, growth, reproduction, and lactation) by secreting hormones. The neurohypophysis functionally connects the gland to the </span>hypothalamus. The intermediate lobe (between adeno and neurohypophysis) synthesizes and secretes melanocyte-stimulating hormone. Because it controls a lot of functions inside the organism it can affect many things when it is not working properly (over- or under-production of pituitary hormones). It can cause diabetes insipidus by a deficiency of vasopressin, it can cause thyroid disorders, gigantism (too much growth hormone)…
