Anatomy Lecture Deck 4 Flashcards
when head orientation changes, gravity pulls on blank which moves blank which deforms hair cell blank and blank occurs
statoconia, otolith, stereocilia, depolarization
eyelids are also known as blank
palpebrae
eyelids functions are to
protect/lubricate
two parts of eyelids
tarsal glands, conjunctiva
oily secretions keep lids from sticking together in eyelid

sharper
there are blank types of cones
three
three regions of the retina

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
