Endo
| Question | Answer |
|---|---|
| endocrine system functions | acts with the nervous system to coordinate functions of all other body systems- releases hormones/mediators/-hormones act on target cells which are cells that have the specific hormone receptor- slower and longer lasting response |
| endocrine glands | pituitary thyroid parathyroid pineal adrenal |
| hormone | excite or get moving- these are chemical messengers released by one tissue /gland/ and transported by the bloodstream to reach the target tissues |
| hypothalamus | connection between the nervous and endocrine system- releases hormones/ RFs and IFs/ that controls the release of hormones from the anterior pituitary gland |
| Antidiuretic hormone /ADH/ | influences the absoption of water by kidney tubules |
| oxytocin hormone | produce- hypothalamus released- posterior pituitary target- uterus, mammary gland functions- stimulates uterine contraction during childbirth and milk release |
| pituitary gland | most influential gland -master gland- under the influence of the hypothalamus, the pituitary regulates growth and controls other endocrine glands |
| growth hormone /HGH/ | anterior pituitary gland targets all cell bodies stimulates cell growth and repair |
| thyroid stimulating hormone /TSH/ | stimulates secretion from thyroid gland which regulates metabolism |
| Adrenocorticotropic hormone /ACTH/ | stimulates adrenal cortex to secrete glucoscorticoids from the adrenal glands |
| thyroid gland | endocrine glands that surrounds the trachea in the neck |
| thyroxine ./T4/ | regulates metabolism |
| triiodothyronine /T3/ | thyroid hormone that stimulated cellular metabolism |
| adrenal glands | a pair of endocrine glands that sit just above the kidneys and secrete hormones |
| adrenal cortex | the outer portion of the adrenal glands |
| adrenal medulla | inner portion of the adrenal glands |
| cortisol | stress hormone released by the adrenal cortex |
| epinenphrine | fight or flight |
| Norepinephrine | Helps control alertness and arousal |
| pancreas | regulates the level of sugar in the blood |
| glucagon | a protein hormone secreted by pancreatic endocrine cells that raises blood glucose levels |
| insulin | a protein hormone synthesized in the pancreas that regulates blood sugar levels by facilitating the uptake of glucose into tissues |
| hypothyroidism | condition of hyposecretion of the thyroid gland causing low thyroid levels in the blood that result in sluggishness slow pulse and often obesity |
| hyperthyroidism | excessive activity of the thyroid gland |
| gigantism | hypersecretion of growth hormone from the anterior pituitary before puberty leading to abnormal overgrowth of body tissues |
| acromegaly | abnormal enlargement of the extremities |
| dwarfism | condition caused by insufficient growth hormone in childhood |
| cretinism | condition of congenital hypothyroidism in children that result in lack of mental development and dwarfed physical stature- the thyroid gland is either congenitally absent or imperfectly developed |
