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
