| Question | Answer |
|---|---|
| Anterior Pituitary Hormones TROPIC (4) | 1. TSH 2. FSH 3. LH 4. ACTH |
| Anterior Pituitary Hormones NOT TROPIC (2) | 1. GH 2. PRL |
| TSH Stimulus | Thyroid-Releasing Hormone (TRH) |
| TSH Gland | Anterior Pituitary |
| TSH Target cell | Thyroid |
| TSH Response | Secretion of T3 and T4 (BMR + Growth Rate) |
| FSH Stimulus | Gonadtroponin-Releasing Hormone (GnRH) |
| FSH Gland | Anterior Pituitary |
| FSH Target Cell | Ovaries + Testes |
| FSH Response (F) | Stimulates ovarian follicle maturation and estrogen production |
| FSH Response (M) | Stimulates sperm production |
| LH Stimulus | Gonadtroponin-Releasing Hormone (GnRH) |
| LH Gland | Anterior Pituitary |
| LH Target cell | Ovaries + Testes |
| LH Response (F) | Triggers ovulation follicle maturation and estrogen production |
| LH Response (M) | Stimulates testosterone production |
| ACTH Stimulus | Corticotroponin-Releasing Hormone (CRH) |
| ACTH Gland | Anterior Pituitary |
| ACTH Target Cell | Adrenal Cortex |
| ACTH Response | Stimulates the release of Glucocorticoids and Androgens |
| GH Stimulus | Growth Hormone-Releasing Hormone (GHRH) |
| GH Gland | Anterior Pituitary |
| GH Target Cell | Liver, muscle, bone, cortex |
| GH Response | Stimulates body growth and protein synthesis mobilizes fat and conserves glucose |
| PRL Stimulus | A decrease in the amount of Prolactin-inhibiting hormone |
| PRL Gland | Anterior Pituitary |
| PRL Target Cell | Mammary glands in the breasts |
| PRL Response | Milk production |
| Posterior Pituitary Gland Hormones | 1. Oxytocin 2. ADH |
| Oxytocin Stimulus | Nerve impulses from Hypothalamic neurons in response to cervical/uterine stretch or suckling |
| Oxytocin Gland | Posterior Pituitary |
| Oxytocin Target Cell | Uterus and Mammary |
| Oxytocin Response | Contractions and lactation |
| ADH Stimulus | Nerve impulses from hypothalamic neurons in response to increase blood solute concentration or decreased blood volume |
| ADH Gland | Posterior Pituitary |
| ADH Target Cell | Kidneys |
| ADH Response | Stimulates the kidneys to reabsorb more water, reducing urine output and conserving body water |
| Thyroid and Parathyroid Gland Hormones | 1. T3 + T4 (thyroid 2. PTH (parathyroid) |
| T3 + T4 Stimulus | Thyroid-Stimulating Hormone (TSH) |
| T3 + T4 Gland | Thyroid |
| T3 + T4 Target Cell | Most cells in body |
| T3 + T4 Response | Increase BMR + Regulates tissue growth development |
| PTH Stimulus | Low levels of Ca in blood |
| PTH Gland | Parathyroid |
| PTH Target Cells | Bones and kidneys |
| PTH Response | Increase Ca by stimulating osteoclasts and making kidneys reabsorb Ca Also stimulates kidneys into converting vitamin D into Calcitriol |
| Adrenal Gland Hormones Cortex | 1. Mineralocorticoids (mostly aldosterone) 2. Glucocorticoids (mostly cortisol) 3. Gonadocorticoids (mostly androgens) |
| Adrenal Gland Hormones Medulla | Catecholamines |
| Mineralocorticoids (mostly aldosterone) Stimulus | Angio tensin II release + increased K+ in the blood |
| Mineralocorticoids (mostly aldosterone) Gland | Adrenal Cortex |
| Mineralocorticoids (mostly aldosterone) Target Cells | Most body cells |
| Mineralocorticoids (mostly aldosterone) Response | Increase in reabsorption of K+ and H2O by the kidenys Increase secretion of K+ in urine |
| Glucocorticoids (mostly cortisol) Stimulus | ACTH |
| Glucocorticoids (mostly cortisol) Gland | Adrenal Cortex |
| Glucocorticoids (mostly cortisol) Target Cells | Most body cells |
| Glucocorticoids (mostly cortisol) Response | Promotes the breakdown of fat an dprotein Promotes stress resistance and inhibits the immune response |
| Gonadocorticoids (mostly androgens) Stimulus | ACTH |
| Gonadocorticoids (mostly androgens) Gland | Adrenal Cortex |
| Gonadocorticoids (mostly androgens) Target Cells | Bones, muscles, integuements and other tissues |

| Gonadocorticoids (mostly androgens) Response (M) | Not much |
| Catecholamines (Epin + Norep) Stimulus | Nerve impulses from preganglionic sympathetic fibers |
| Catecholamines (Epin + Norep) Gland | Adrenal Medulla |
| Catecholamines (Epin + Norep) Target Cells | Most body cells |
| Catecholamines (Epin + Norep) Response | Mimics sympathetic NS (fight or flight) |
| Pancreas Hormones | 1. Insulin 2. Glucagon |
| Insulin Stimulus | Increase of blood glucose levels, parasympathetic NS stim |
| Insulin Gland | Pancreas |
| Insulin Target Cell | Most cells of the body |
| Insulin Response | Drops your blood glucose levels |
| Glucagon Stimulus | Decrease of blood glucose levels, sympathetic NS stim |
| Glucagon Gland | Pancreas |
| Glucagon Target Cell | Liver and Adipose |
| Glucagon Response | Increases your blood glucose levels |
