The anterior pituitary gland, also known as the adenohypophysis, is a small, pea-sized gland located at the base of the brain. It is responsible for producing and secreting a number of important hormones that regulate various bodily functions, including growth, reproduction, and metabolism. Synonyms for the anterior pituitary gland include the anterior lobe of the pituitary gland, the frontal lobe of the pituitary gland, and the pars anterior. The anterior pituitary is connected to the hypothalamus by a system of blood vessels, allowing for the release of hormones in response to signals from the brain. Any disruption in the function of this gland can have significant effects on a person's health and wellbeing.
