Study Notes

Hormones of the Endocrine System

Thyroid Stimulating Hormone (TSH): Produced by anterior pituitary gland; targets thyroid; stimulates release of T3 and T4 hormones, crucial for metabolism.
Adrenocorticotropic Hormone (ACTH): Secreted by anterior pituitary gland; targets adrenal gland; stimulates glucocorticoid production, important for stress response.
Follicle Stimulating Hormone (FSH): Released by anterior pituitary; targets ovaries and testes; promotes estrogen secretion, egg development, and sperm production.
Luteinizing Hormone (LH): Anterior pituitary hormone; acts on ovaries and testes; triggers ovulation, progestin production in females, and androgen production in males.
Prolactin (PRL): From anterior pituitary; targets mammary glands; essential for milk production post childbirth.
Growth Hormone (hGH): Secreted by anterior pituitary; influences all cell types; stimulates growth, reproduction, and repair of tissues.
Melanocyte Stimulating Hormone (MSH): Produced by anterior pituitary; targets melanin-producing cells; stimulates melanin production for skin pigmentation.
Antidiuretic Hormone (ADH): Comes from posterior pituitary; targets kidneys; reduces water loss, increases thirst by conserving water.
Oxytocin: From posterior pituitary; targets uterus, mammary glands, and prostate; induces contractions in labor and milk ejection during breastfeeding.
Calcitonin: Secreted by thyroid's C cells; targets kidneys and osteoclasts; lowers blood calcium levels and inhibits bone resorption.
Triiodothyronine (T3): Released by thyroid; affects most body cells; increases metabolism and heat production, critical for energy balance.
Thyroxine (T4): Derived from thyroid; targets most body cells; also increases metabolism and heat production.
Parathyroid Hormone (PTH): Secreted by parathyroid glands; targets osteoclasts, kidneys, and intestines; raises blood calcium levels by stimulating bone resorption and enhancing intestinal absorption.
Aldosterone: Produced in adrenal cortex; targets kidneys; reduces sodium and water loss, thus increasing blood pressure.
Cortisol: Hormone from adrenal cortex; affects liver, muscles, and immune cells; regulates glucose metabolism and reduces inflammation.
Androgens: Produced in adrenal cortex; targets sex organs; essential for reproduction and development of male secondary sexual characteristics.
Melatonin: Secreted by pineal gland; targets brain cells and hypothalamus; regulates sleep-wake cycles based on light exposure.
Epinephrine: Produced by adrenal medulla; targets nervous system; prepares body for fight-or-flight response.
Norepinephrine: Also from adrenal medulla; targets nervous system; plays a role in fight-or-flight response.
Insulin: Released by pancreas; targets body cells; lowers blood sugar levels by facilitating glucose uptake.
Glucagon: Produced by pancreas; targets liver and muscles; increases blood sugar levels through glycogen breakdown.
Atrial Natriuretic Peptide (ANP) and Brain Natriuretic Peptide (BNP): Produced by heart; affects kidneys; promotes sodium and water loss, leading to lower blood pressure.
Thymosin: Secreted by thymus; targets lymphocytes; stimulates immune cell maturation and function.
Testosterone: Produced by testes; targets skeletal and muscle cells; initiates male sexual characteristic development and reproduction.
Inhibin: Secreted by testes; targets sperm; facilitates maturation of spermatozoa, including development of flagella and enzyme packets.
Estrogen: Produced by ovaries; targets adipose tissue and ovaries; stimulates fat storage and female sexual characteristic development.
Progesterone: Secreted by ovaries; targets uterus; prepares the body for pregnancy by regulating the menstrual cycle.
Leptin: Produced by adipose tissue; targets brain's feeding center; signals fullness after meals, regulates GnRH levels.
Resistin: Secreted by adipose tissue; reduces insulin sensitivity, possibly contributing to insulin resistance.
