Study Notes
Hormones and the Endocrine System
- The main function of hormones in the endocrine system is to regulate various bodily functions.
- Hormones are signaling molecules secreted into the blood by endocrine glands.
Hormone Function and Signaling
- When a hormone binds to a cell receptor, it triggers a response, leading to changes in cellular activity.
Hormone Transportation and Action
- Hormones produced in endocrine glands travel through the bloodstream to control body processes.
- The hypothalamus is an integral part of the endocrine system.
Hypothalamus and Hormone Regulation
- The hypothalamus releases somatostatin, a hormone that inhibits the secretion of growth hormone.
- Neurosecretory cells in the hypothalamus release oxytocin and antidiuretic hormone (ADH) into the posterior pituitary gland.
- The posterior pituitary gland stores and secretes oxytocin and ADH.
ADH Production and Regulation
- The paraventricular nuclei produce the antidiuretic hormone (ADH).
- Factors such as environmental stimuli, physiological changes, and other hormones can affect hormone secretion.
