Endocrine ANAT
Question | Answer |
---|---|
endocrine function | communication and control of bodily processes through secretions into the blood - slower communication than nervous, longer lasting effect |
hormone's various functions | reproductions cycles - cellular metabolism - bodily growth - fluid and electrolyte balance - pH balance - MAINTAIN HOMEOSTASIS |
two types of glands | exocrine - endocrine |
releases products into ducts that lead to surface of body and/or into other organs | exocrine |
hormone release into blood directly -> the blood takes the hormone to the target cell | endocrine |
the cell affected by hormones | target cell |
a chemical messenger used to produce cellular function | hormone |
4 classes of hormones | protein - steroid - prostaglandins - tropic hormones |
bind to receptors w/in the target cell membrane -> triggers second response inside the cell | protein hormone |
lipid based - slips through phospholipid bilayer - delivers message to nucleus, telling which gene needs to be transcribed -> leaves cell and becomes muscle | steroid hormone |
tissue hormone - released from gland into surrounding tissue | prostaglandins |
special hormone that targets other endocrine glands to release their hormones | tropic hormone |
the control system of the endocrine system | the hypothalamus |
the hypothalamus controls the endocrine system through this gland | pituitary gland |
tropic hormones are found in what gland | pituitary |
two ways to regulate hormone action | negative and positive feedback |
opposes a change in the body to return the body to homeostasis | negative feedback |
amplifies a change in the body to return the body to homeostasis | positive feedback |
gland that rest under the hypothalamus on the sella turcica - sella turcica is a protective bone for this gland | pituitary |
the 4 tropic hormones _ANTERIOR PITUITARY | thyroid stim. H - adrenocorticotropic H - follicle stem. H - letenizing H _ANTERIOR PITUITARY |
stims thyroid gland _ANTERIOR PITUITARY | TSH _ANTERIOR PITUITARY |
stims. adrenal gland to produce its hormone _ANTERIOR PITUITARY | ACTH _ANTERIOR PITUITARY |
stimulates ovary -> estrogen production - stims testes -> produces sperm _ANTERIOR PITUITARY | FSH _ANTERIOR PITUITARY |
ovary -> progesterone, ovulation stims testes -> testosterone production _ANTERIOR PITUITARY | LH _ANTERIOR PITUITARY |
stims the release of melanin in the skin - disease: albinism -> lack f pigment in the skin, hair, etc ANTERIOR PITUITARY | melanocyte stim H _ANTERIOR PITUITARY |
increased blood sugar - stims growth -_ANTERIOR PITUITARY | growth hormone _ANTERIOR PITUITARY |
too much sugar in the blood _ANTERIOR PITUITARY | hyperglycemia _ANTERIOR PITUITARY |
female only - breast development - lactation _ANTERIOR PITUITARY | prolactin _ANTERIOR PITUITARY |
