Endocrine System - 1
Glands of Human Endocrine System and their Hormones
| Term | Definition |
|---|---|
| Hypothalamus Hormones | Hypothalmic Releasing Hormones & Hypothalmic Inhibiting Hormones |
| Hypothalmic Releasing Hormone | Stimulates Anterior pituitary gland to secrete its hormones. |
| Hypothalmic Inhibiting Hormones | Inhibits Anterior pituitary gland from secreting its hormones. |
| Posterior Pituitary Gland Hormones | OT - Oxytocin ADH - Antidiuretic Hormone |
| OT - Oxytocin | Stimulates uterine contraction during labor. Promotes female milk ejection by mammary glands |
| ADH - Antidiuretic Hormone | Stimulates water reabsorption by kidneys Vasoconstriction of arterioles Inhibits sweat glands |
| Anterior Pituitary Gland Hormones | Growth Hormone(GH), Thyroid Stimulating Hormone (TSH),Follicle Stimulating Hormone (FSH), Luteinizing Hormone (LH), Prolactin (PRL), Adrenocorticotropic Hormone (ACTH) |
| Growth Hormone(GH) | Stimulates growth and metabolism |
| Thyroid Stimulating Hormone (TSH) | Stimulates thyroid gland to secrete Thyroid Hormone (TH) |
| Follicle Stimulating Hormone (FSH) | Females - maturation of eggs & secretion of estrogens Males - Sperm prodcution |
| Luteinizing Hormone (LH) | Females - Ovulation, Corpus Luteum, secretion of progesterone Males - secretion of testosterone, LH AKA ICSH (Interstitial cell Simulating Hormone) |
| Prolactin (PRL) | Stimulates Milk production by mammary glands |
| Adrenocorticotropic Hormone (ACTH) | Stimulates adrenal cortex to secrete its hormones |
| Thyroid Gland Hormones | Thyroid Hormones (TH), Thyroxine (T4), Triiodothyronine (T3), Calcitonin (CT) |
| Thyroid Hormones (TH), Thyroxine (T4), Triiodothyronine (T3) | Increases metabolic rate, body temperature,stimulates protein synthesis |
| Calcitonin (CT) | Lowers blood calcium level and inhibits bone resorption |
| Parathyroid Glands Hormones | Parathyroid Hormone(PTH) |
| Parathyroid Hormone(PTH) | Raises blood calcium level, increases activity of osteoclasts, increases intertinal absorption of calcium, promotes kidney resorption of calcium & secretion of phosphate. |
| Adrenal Cortex Gland Hormones | Aldosterone, Mineralocorticoids, Cortisol, Glucocorticoids, Androgens, Gonadocorticoids |
| Aldosterone & Mineralocorticoids | Stimulates kidneys to reabsorb Na+ & secrete K+ |
| Cortisol & Glucocorticoids | Increasees blood glucose level, breakdown of protein, fat for energy, inhibits inflammatory and immune responses. |
| Androgens & Gonadocorticoids | Contribute to onset of puberty development of axillary & pubic hair |
| Adrenal Medulla Gland Hormones | Epinephrine(Epi)(aka - Adrenaline), Norepinephrine (NE) (aka - Noradrenaline) |
| Epinephrine(Epi)(aka - Adrenaline) and Norepinephrine (NE) (aka - Noradrenaline) | fight or flight response; stimulates heart and lungs, increase blood pressure, increases metabolic rate, and increases blood glucose. |
| Pineal Gland Hormones | Melatonin |
| Melatonin | set body's biological clock, regulates sleep-wake cycle |
| Pancrease Hormones | Glucogen, Insulin |
| Glucogen | Raises blood glucose leve, gycogen breakdown (glcogenolysis) adn stimulates formation of new glucose from noncarbohydreates (gluconeogenesis) |
| Insulin | Loweres blood glucose level, stimulates glucose uptake by cells, fromation of glycogen (glycogenesis), formation of fat (lipogenesis) |
| Female Gonads(Ovaries) Hormones | Estrogen and progesterone |
| Estrogen and progesterone | Stimulate female sex characteristics, regulate menstrual cycle, maintain pregnancy |
| Male Gonads (Testes) | Testosterone |
| Testosterone | Stimulate male sex characteristics, regulate sperm production |
| Thymus Gland Hormones | Thymosin, Thymopoietin, and Thymulin(Thymic factor) |
| Thymosin, Thymopoietin, and Thymulin(Thymic factor) | Stimulate differentiation & maturation of T lymphocytes (T cells) |
