Anterior pituitary
Anterior Pituitary
The Anterior Pituitary (pronounced: an-TEER-ee-or pih-TOO-uh-ter-ee), also known as the adenohypophysis, is a gland located at the base of the brain. It is part of the endocrine system and is responsible for the production and release of several key hormones that regulate a variety of bodily functions.
Etymology
The term "anterior pituitary" is derived from the Latin words "ante" meaning "before", and "pituita" meaning "phlegm" or "slime". This is in reference to the gland's position at the front (anterior) of the pituitary gland, which was once thought to produce mucus.
Function
The anterior pituitary produces and releases several hormones, including:
- Growth hormone (GH)
- Thyroid-stimulating hormone (TSH)
- Adrenocorticotropic hormone (ACTH)
- Follicle-stimulating hormone (FSH)
- Luteinizing hormone (LH)
- Prolactin (PRL)
These hormones play crucial roles in growth, metabolism, sexual development, and stress response.
