| Question | Answer |
|---|---|
| How is endocrine gland different from exocrine? | Enod-secrets into fluid that surrounds tissue cells. Exo- secrets into ducts that then secrets into body cavities, then into luman of organ or skin. |
| What is a target cell? | A cell that is affected by a particular hormone. |
| What is a receptor site? | A specfic binding site for a hormone. It allows the hormone to bind to it and be reconized. |
| Where are receptor sites located? | Lipid soluable: INSIDE target cells. Water soluable: Part of the plasma membrane of target cells. |
| How are secretions controlled? | 1: signals from nervous systems 2: chemoical changes in the bloos 3: Other hormones |
| Give examples of how secretions are controlled? | 1: Nerve impluses regulate the release of epinphrine 2: Blood Ca level regulates secretions of parathyoid gland 3: Hormone from ACTH stimulates release of cortisol by the adrenal cortex |
| What is the cause and symtoms of HYPERINSULINISM? | Cause: Diabetic injects too much insuilin Symptoms: Hypoglycemia, mental disorientation, concussions, shock. |
| What is the cause and symtoms of TYPE 2 DIABETES? | Cause: over weight, over 35, target cells arent as sensitive to insulin. SYmpt: high glucose levels can be controlled by diet and exersize |
| What is the cause and symtoms of TYPE 1 DIABETES? | Cause:genetic and enviornmental factors Sympt: Insulin level is low b/c system destroys pancreatic beta cells |
| What is the cause and symtoms of Addisons disease? | Cause: Hypersecretion of glucocorticoids Sympt: Mental lethargy, anorexia, bronzed skin |
| What is the cause and symtoms of Cushings disease? | Cause:Hypersecretion of glucocorticoids, breakdown of muscle protiens Symt: redistrbution of body fat, spindly arms/legs, "moon face", mood swings |
| What is nueropathy? | Disease of nerves that is common with diabetes |
| What is hypophysectomy? | Removal of pituitary gland |
| What is gangrene? | The death of tissue, secondary to low oxygen levels. |
| What is emaciation? | Extremely thin, wasting. |
| What is diaphoresis? | Excessive sweating |
| What is cachexia? | Malnutrition, wasting |
| What is anorexia? | loss of appetite |
| What is acidosis? | Accumulation of acids in the blood that is a sympton of diabetes |
| What is acromegaly? | Enlarged and distorted extremities of the face |
| Prefix lacto | Meaning, milk. |
| Hormone LH | Luteinizing Hormone Stimulates ovulation, prepares mammary glands, stimulates testosterone secretion |
| Insulin | Hormone secreted by beta cells of pancreatic lislet, DECREASES blood glucose level |
| Glucagon | INCREASES bloos glucose levels |
| Cortisol | Breakdowns proteins, form glucose |
| Proesteron | Female sex hormone produced by ovaries, prepares uterus for fertilaztion |
| Nor/Epinephrine | Hormone secreted by adrenal medulla |
| Estrogen | Female sex hormone, regulates menstral cycle, maintains pregnancy, prepares mammary glands |
| Oxytocin | Ehances contraction of smooth muscle in uterus, stimulates milk enjection |
| Hormone IGF | Insulinlike Growth Factors Maintains muscle and bone mass Similar to insulin Stimulate protein syntheis |
| Hormone hGH | Human Growth Hormone Promote synthesis and secretion of small protein hormones |
| Hormone PRL | Prolactin Initiates and Maintains milk production in mammary glands |
| Hormone PIH | Supresses release of PRL |
| Hormone PHR | Stimulates release of PRL |
| Hormone ADH | Antidiuretic Hormone Decreases Urine production Causes kidneys to retain more water, decreases water loss through sweating. |
| Hormone GHRH | Growth Hormone Releasing Hormone Promotes secretion of Human Growth Hormone |
| Hormone GHIH | Growth Hormone Inhibiting Hormone Supresses secretion |
| Hormone TSH | Thyroid- Stimulating Hormone Stimulates the synthesis and secretion of thyroid hormones in thyroid gland |
| What is the difference between Hormones T3 and T4? | t3 has 3 atoms of iodine t4 has 4 atoms of iodine |
