Ch 19 Lec 1 - Endocrine System Flashcards
endocrine system is blank with blank effects
slow, long term
endocrine system is interrelated with the blank system
nervous
the blank directly innervates the endocrine system
hypothalamus
hormones produced by specialized cell and carried in blood stream
ductless system
exocrine uses a blank
duct
endocrine hormones go to blank
everywhere
substance synthesized by a specific organ or tissue and secreted
hormones
blood carries hormones to other sites which is called blank
endocrine signaling
hormones secreted into extracellular spaces which is called blank
paracrine signaling
hormones act on blank
target cells
target cells have specific blank for specific hormones
receptors
four categories of hormones
steroids, peptides, amines, eicosanoids
hormones that are made of cholesterol and non polar
steroids
hormones that are polar
peptides
hormones that are derived from amino acids and are polar or non polar
amines
hormones that are mostly non polar and are paracrine signals
eicosanoids
steroids can cross blank
membranes
derived from tyrosine or tryptophan
amine hormones
some are membrane blank and others are not
soluble
most important amine hormones are made by blank and blank
thyroid, adrenal medulla
short chaiins of amino acids and are too big to cross membranes and are all pituitary hormones
peptide hormones
control of hormone secretion is an example of blank
negative feedback
in negative feedback, blank is established and it works just like a blank
homeostasis, furnace
hypothalamus sends signals to the body and the blank gland
pituitary
pituitary gland is the most important endocrine gland for blank
regulation
two lobes of pituitary gland
posterior, anterior
posterior lobe of pituitary gland does not make any blank
hormones
posterior lobe of pituitary is mostly for blank
hypothalamic axons
anterior lobe of pituitary has blank types of endocrine cells
five
two hypothalamic regulatory hormones of the anterior pituitary lobe
releasing, inhibiting
eicoanoids are mostly blank and are blank
non polar, prostaglandins
posterior pituitary hormone that causes contraction of muscles in uterine walls
oxytocin
oxytocin also causes muscles associated with milk ejection to blank as well as prostate gland
contract
oxytocin is significant in blank bonding
emotional
posterior pituitary hormone that caused kidney to decrease water excretion
antidiuretic hormon
antidiuretic hormone increased blank
blood volume
anterior pituitary hormone that causes increase in melatonin secretion
melanocyte stimulating hormone
anterior pituitary hormone that causes tested to produce sperm, follicular development in ovary and stimulate secretion of estrogen
follicle stimulating hormone
anterior pituitary hormone that promotes secretion of sex hormones and releases oocyte
luteinizing hormone
anterior pituitary hormone that increases size and rate of reproduction of body cells like muscles and bones
growth hormone
growth hormone is secreted throughout life but increases at blank
puberty
anterior pituitary hormone that controls secretion of thyroid hormone
thyroid stimulating hormone
anterior pituitary hormone that targets mammary tissue to produce milk
prolactin
anterior pituitary hormone that stimulates adrenal cortex to produce corticosteroids
adrenocorticotropic hormone
two lobes and isthmus connecting this gland
thyroid
thyroid is inferior to blank
larynx
thyroid has blank cells
follicular
follicular cells remove blank from blood
iodine
follicular cells secrete blank
T3 and T4
