Hormones of the Endocrine System
| Question | Answer |
|---|---|
| Location and function of the Human Growth Hormone.. (GH) | Location: Anterior Pituitary Gland Function: Control Growth of a body. Targets bone, muscle and adipose tissue |
| Location and function of the hormone Prolactin (PRL).. | Location: Anterior Pituitary Gland Function:Stimulates the production of milk by the mammary glands, targets the mammary glands |
| Location and function of the Thyroid Stimulating Hormone (TSH) | Location: Anterior Pituitary Gland Function: Controls secretion of hormones by the thyroid gland, targets the thyroid |
| Location and function of the Adrenocorticotropic Hormone (ACTH) | Location: Anterior Pituitary Gland Function: Controls the secretion of hormones by the adrenal cortex, targets the outer portion of the adrenal gland |
| Location and function of the Follicle stimulating hormone (FSH) | Location: Anterior pituitary gland Function: response depends on the sex: Female:Stimulates maturation of an ovarian follicle and ovum Males: stimulates maturation of sperm in the testes A gonadotropin, which targets primary sex organs (Ovary & Teste |
| Location and function of the Luteinizing Hormone (LH) | Location: Anterior Pituitary Hormone Function: Response depends on sex Female: Causes ovulation Male: Causes secretion of testosterone A gonadotropin which targets ovaries and testes. |
| Location and function of antidiuretic Hormone (ADH).. | Location: Posterior Pituitary Gland Function: Targets distal convoluted tubules (of kidneys), Causes DCT's to reabsorb the water back into the bloodstream, and therefor controls water balance and (increases) blood pressure. Also called vasopressin. |
| Location and function of the Oxytocin Hormone. | Location: Posterior Pituitary Gland Function: Targets uterine smooth muscle and breasts, causes uterine muscle contraction and milk production |
| Location and function of the hormone Thyroxine (T4) & Triiodothyronine (T3).. | Location: Thyroid Gland Function: Increase basal metabolic rate by stimulating cellular oxygen use and produce ATP. REGULATE METABOLISM |
| Location and Function of the hormone calcitonin. . . | Location: Thyroid Gland Function: Target bone cells(stimulates osteoblast activity and inhibits osteoclast activity) & distal convoluted tubules (causes secretion of excess calcium into urine. |
| Location and function of the hormone called Parathyroid Hormone (PTH) | Location: Parathyroid Gland Function: Stimulated by the decrease of blood calcium,PTH causes an INCREASE IN BLOOD CALCIUM (and phosphate)and brings levels back to normal. |
| Location and function of the hormones epinephrine and norepinephrine. | Location: Adrenal Glands Function: Target the heart (SA node to increase the heart rate) Targets smooth muscle, Peripheral arterioles(vasoconstriction, which increases blood pressure, and terminal brachioles (bronchodialation,inreases depth of breathing) |
| Location and function of the hormone Aldosterone. | Location: Adrenal Cortex Function: Targets distal convoluted tubules (in the kidneys) causing reabsorption of water and electrolytes back into the blood. (increases blood pressure). |
| Location and function of the Hormone Cortisol. | Location: Adrenal Cortex Function: Targets all cells, where it regulates glucose metabolism (along with T3&T4) |
| Location and function of the Hormone Glucagon. | Location: Pancreatic Islets Function: Secretion is stimulated by decreased blood glucose levels (ie; fasting). Increases blood glucose levels (ie; causes breakdown of glycogen and releases glucose into the bloodstream). |
| Location and function of the Hormone Insulin. | Location: Pancreatic Islets Function: Secretion in stimulated by increased blood glucose levels (ie; after eating). decreases blood glucose levels (ie; moves glucose from bloodstream into cells and promote glycogen formation in liver and skeletal muscle. |
| Location and function of the Hormone Melatonin.... | Location: Pineal Gland Function: Production is stimulated by daylight (circadian rhythm), affects moods, emotion, etc. |
| Location and function of the Hormone Thymosin. | Location: Thymus Gland Function: Affects the maturation of lymphocytes (T-Cells). |
| Location and function of the Hormone Estrogen. | Location: Ovaries Function: Develops female secondary sex characteristics (at puberty) and maintains them throughout life. Targets mammary glands, internal and external genitalia and adipose tissue in hips thighs and buttocks. |
| Location and function of the Hormone Progesterone. | Location: Ovaries Function: Prepares the uterine lining for implantation of the zygote. |
| Location and function of the Hormone Testosterone. | Location: Testes Function: Develops male secondary sex characteristics at puberty and maintains them throughout life. Targets: hair follicles, genitalia, muscle and bone, and vocal cords in larynx (thicken, resulting in deeper voice). |
