Study Notes
Overview of the Endocrine System
The endocrine system is a network of glands and organs that produce and regulate hormones in the body.
Functions of the Endocrine System
- Regulates growth and development
- Controls metabolism and energy balance
- Manages electrolyte and water balance
- Regulates reproductive processes
- Maintains homeostasis
Major Endocrine Glands
-
Pituitary Gland: "Master gland" that regulates other endocrine glands
- Produces hormones that stimulate other glands
- Regulates growth and development
-
Thyroid Gland: Produces thyroid hormones that regulate metabolism
- Thyroxine (T4): Regulates metabolism and energy
- Triiodothyronine (T3): Regulates metabolism and energy
-
Adrenal Glands: Produce hormones that regulate stress response and electrolyte balance
- Adrenaline (Epinephrine): Regulates "fight or flight" response
- Aldosterone: Regulates electrolyte and water balance
-
Pancreas: Produces hormones that regulate blood sugar levels
- Insulin: Lowers blood sugar levels
- Glucagon: Raises blood sugar levels
-
Ovaries (in females): Produce hormones that regulate reproductive processes
- Estrogen: Regulates female reproductive cycle
- Progesterone: Regulates female reproductive cycle
-
Testes (in males): Produce hormones that regulate reproductive processes
- Testosterone: Regulates male reproductive cycle
Hormones and Their Functions
- Insulin: Lowers blood sugar levels
- Glucagon: Raises blood sugar levels
- Adrenaline (Epinephrine): Regulates "fight or flight" response
- Aldosterone: Regulates electrolyte and water balance
- Thyroxine (T4): Regulates metabolism and energy
- Triiodothyronine (T3): Regulates metabolism and energy
- Estrogen: Regulates female reproductive cycle
- Progesterone: Regulates female reproductive cycle
- Testosterone: Regulates male reproductive cycle
Disorders and Diseases of the Endocrine System
- Diabetes: Insufficient insulin production or resistance to insulin
- Hypothyroidism: Insufficient thyroid hormone production
- Hyperthyroidism: Excessive thyroid hormone production
- Cushing's Syndrome: Excessive adrenal hormone production
- Adrenal Insufficiency: Insufficient adrenal hormone production
