The pituitary gland is a small, pea-sized endocrine gland located at the base of the brain. Despite its small size, it has several critical functions in regulating hormones throughout the body. The pituitary is often referred to as the "master gland" because it controls the function of most other endocrine glands.
The pituitary has two main lobes - the anterior and posterior lobes. The anterior lobe secretes hormones that regulate several processes including growth, reproduction, lactation, and stress. Key hormones secreted by the anterior pituitary include:
- Growth hormone (GH) - stimulates growth of bones and tissues
- Thyroid stimulating hormone (TSH) - regulates thyroid hormone production
- Adrenocorticotropic hormone (ACTH) - stimulates cortisol secretion by adrenal glands
- Follicle stimulating hormone (FSH) and luteinizing hormone (LH) - regulate ovulation and testosterone production
- Prolactin - stimulates breast milk production after pregnancy
The posterior pituitary stores and releases two hormones produced by the hypothalamus -
oxytocin and
antidiuretic hormone (ADH). Oxytocin stimulates uterine contractions during childbirth and milk ejection during breastfeeding. ADH regulates fluid balance in the body.
Diseases that affect pituitary function can have widespread effects on the body. For example, a
pituitary adenoma is a benign tumor that may secrete excess hormones, leading to problems like gigantism, acromegaly, or hormone deficiencies. Other disorders like
pituitary apoplexy can suddenly damage pituitary function.
