A group of cells that secrete hormones into the bloodstream.
How does the endocrine system work?
How does the endocrine system work?
The endocrine system uses chemical messengers called hormones to regulate various bodily functions.
What is the role of the hypothalamus?
What is the role of the hypothalamus?
The hypothalamus, a brain region, controls involuntary functions like body temperature and hormone release, and signals the pituitary gland when necessary.

Study Notes
The Endocrine System
- Endocrine system composed of glands secreting hormones affecting almost every body part
- Hormones released directly into bloodstream, regulating growth, development, metabolism, reproductive processes, and moods
- Hormones are chemical regulators
Glands of the Endocrine System
-
Hypothalamus: Located on underside of brain, controls involuntary functions (e.g., body temperature), monitors conditions (pH, temperature), and signals pituitary gland if correction needed
-
Pituitary Gland: Master endocrine gland in vertebrates, controlling other endocrine glands; secretes hormones stimulating various functions
- Growth Hormone: Stimulates growth
- Oxytocin: Stimulates uterine/breast muscle contractions
- Vasopressin: Stimulates water reabsorption from kidneys
- Prolactin: Stimulates milk secretion
- Adrenocorticotropic Hormone (ACTH): Stimulates cortisol release from adrenal glands
- Luteinizing Hormone: Maturation of eggs, corpus luteum surrounding egg and female sex hormones
- Follicle Stimulating Hormone: Egg maturation in ovaries affecting female sex hormones and menstrual cycle
-
Thyroid Gland: Located in front of larynx, regulating metabolism and calcium
- Thyroxin: Regulates metabolism
- Calcitonin: Calcium storage in bones, inhibits calcium release from bones
