Study Notes
Endocrine Control System
- The hypothalamus acts as a link between the nervous and endocrine systems, regulating various body functions, such as hunger, thirst, and body temperature.
- The anterior pituitary gland (APG) plays a crucial role in the endocrine control system by producing and regulating hormone production in other endocrine glands.
Hypothalamic-Pituitary Interactions
- The hypothalamus interacts with the posterior pituitary gland (PPG) by producing and transporting hormones, such as oxytocin and vasopressin, down the axons of hypothalamic neurons to the PPG for storage and secretion.
Major Endocrine Glands
- The two major glands involved in endocrine control are the hypothalamus and the pituitary gland.
Hypophyseal Portal System
- The anterior pituitary gland (APG) interacts primarily through the hypophyseal portal system, a network of blood vessels that connects the hypothalamus to the APG.
- An example of a hormone in the hypophyseal portal system is thyrotropin-releasing hormone (TRH).
Hypothalamic Functions
- The hypothalamus is responsible for ultimately controlling the body's hormonal response to the environment.
Hormone Regulation
- The hormone gonadotropin-releasing hormone (GnRH) stimulates the release of gonadotropins, which in turn stimulate the release of gonadal hormones.
