Study Notes
Pituitary Gland
- Located at the base of the brain
- Weighs approximately 0.5 grams in adults
- Plays a crucial role in regulating various bodily functions through hormone production
Functions of the Pituitary Gland
- Produces several hormones that directly affect other endocrine glands and non-endocrine organs
- Regulates growth and development
- Influences reproductive functions
- Helps maintain hormone balance in the body
Structure of the Pituitary Gland
- Divided into two main parts: adenohypophysis and neurohypophysis
- Adenohypophysis, also known as the anterior pituitary, produces several hormones
- Neurohypophysis, also known as the posterior pituitary, stores and releases hormones produced in the hypothalamus
- Pars distalis, a part of the adenohypophysis, produces hormones such as growth hormone, adrenocorticotropic hormone, and prolactin
- Covered with a thin CT capsule
- Attached to the hypothalamic region of the brain by a narrow stalk
