The anterior pituitary gland is a pea-sized organ located at the base of the brain. It is also known as the adenohypophysis. This gland is responsible for producing several hormones such as growth hormone, thyroid-stimulating hormone, adrenocorticotropic hormone and follicle-stimulating hormone. Other synonyms for the anterior pituitary gland include the anterior lobe of the pituitary gland, the front lobe of the pituitary gland, and the pars distalis. It is a vital component of the endocrine system and plays a crucial role in regulating many bodily functions such as growth, metabolism, and reproduction. Dysfunction of the anterior pituitary gland can lead to various disorders and diseases.
