Question | Answer |
How are endocrine and exocrine glands different? | Endocrine glands secret into interitial fluid, fluid that surrounds tissue cells while exocrine glands secrete into ducts that carry its product to a body cavity. |
What are target cells and receptor sites? | Target cells are the specific cell a hormone goes to, the receptor site is what recognizes the specific hormone. |
Where are the receptor sites for lipid soluble and water soluble hormones? | Lipid soluble receptor sites are found within the target cells, water soluble receptor sites are found on the outside of the target cells. |
In what three ways are hormone secretions controlled? | 1.Signals from the nervous system 2. Chemical changes in the blood 3. Chemical changes in other hormones |
What are hGh and IGF, what are their function? | hGh(human growth hormone) -promotes synthesis and secretion of small protein hormones called IGFs. IGF(insulinlike growth factors) -stimulates protein synethesis, helps maintain muscle and bone mass, and promotes healing of innjuries and tissue repair. |
What are GHRH and GHIH, what are their functions? | GHRH(growth hormone-realesing hormone) -hypothalamien that controls secretion of hGh, blood glucose below levels. GHIH(growth hormone-inhibiting hormone) -hypothalamien that controls secretion of hGh, blood glucose above levels. |
What are TSH and TRH, what are their functions? | TSH(thyroid stimulating hormone) -stimulates the synthesis and secretion of theyroid hormones by the thyroid gland. TRH(thyrotropin-releasing hormone) -controls TSH secretion. |
What are FSH, LH, and GnRH, what are their functions? | FSH(folicle stimulating hormone) -developes ovarian follicles -stimulates follicular cells to secrete estrogens(LH) -stimulates sperm production LH(lutenizing hormone) -triggers ovulation GnRH(gonadotropin-releasing hormone) - realse of FSH and LH |
What are PRL, PIH, and PRH, what are their functions? | PRL(prolactin)-initiates and maintains milk prouction in mammary glands. PIH(prolactin-inhibiting hormone) -suppresses the release of prolactin most of the time. PRH(prolactin-releasing hormone) -stimulates release of prolactin. |
What is oxytocin and its function? | 1. enhances contraction of smooth muscle cells int he wall of the uterus during dilivery. 2. stimulates milk ejection after dilivery. |
What is ADH and its function? | ADH(antidiuretic hormone) -decreases urine production -causes kidneys to retain more water -decreases water loss through sweating |
What are T3 and T4, what are their functions? | T3(thyroxine) T4(triiodothyronine) -increases basal metabolic rate(BMR) |
What is glucagon and its function? | Glucagon(hormone) -increases blood glucose levels when they fall below normal, also causes ATP prouction. |
What is insulin and its function? | Insulin(hormone) -helps glucose move into cells, especially muscle fibers. |
What is cortisol and its function? | Cortisol(most abundant glucocorticoid) -breaksdown protein -forms glucose -breaksdown triglycerides -has anti-inflammatory effects |
What are epinepherine and norepinephrine, what are their functions? | Epinepherine and noreponepherine(two main hormones of the adrenal medullae) -fight or flight respones -increase pumping out-put of the heart -increases blood pressure -increases blood flow to some areas |
What are estrogen and progesterone, what are their functions? | Estrogen and progesterone(female sex hormone) -regulates menstral cycle -maintains pregnancy -prepares mammary glands for lactation |
What causes Cushings disease and what are its symptoms? | This is caused by hypersecretion of cortisol, the symptoms are spindly arms and legs, rounded "moon face", "buffalo hump" on the back, and a hanging abdomen. |
What causes Addisons disease and what are its symptoms? | This is caused by hyposecretion of glucocoricoids and aldosterone, the symptoms are mental lethargy, anorexia, weight loss, hypoglycemis, and muscular weakness. |
What causes Typer1 diabetes and what are its symptoms? | This is caused by low insulin leves fur to the immune system hestroying pancreatic beta cells, the symptoms are increasing thirst, frequent urnination, hunger, weight loss, fatique, and blurred vision. |
What causes Type2 diabetes and what are its symptoms? | This is caused by high glucose levels in the blood, the symptoms are increased thirst and hunger, dry mouth, frequent urination, weight loss, fatique, blurred vision, and headaches. |
What causes Hyperinsulism and what are its symptoms? | This is caused when a diabetic injects too much insulin, the symptoms are hypoglycemia, mantal disorientation, convulsions, unconsiousness, and shock. |
