Endocrine System Flashcards
endocrine system controls function by__
release of hormones into blood stream
Hormones have __ effect
Longer
Hormones only effect cells that have proper__
receptors
Amino Acid based Hormone
Water soluble, act on outside of cell
Steroid based hormone
lipid soluble, act on inside of cells
Most hormones are ___ type
water
Water soluble mechanism of action
attach to a receptor on outside of the cell, triggering 2nd messenger inside of cell
Functions of water-soluble hormone
Activate enzymes
stimulate growth
trigger secretion
change membrane premability
Lipid hormone mechanism of action
binds with intracellular receptors inside of cell, binds with dna, triggers portien production
ex: steroid and thyroid hormone
Hormonal Stimulation
one hormone triggers release of another
ex: thyroid stimulating hormone– thyroid hormone
Humoral Stimulation
blood chemistry trigger hormone release
ex: increase blood glucose– release insulin
Neural Stimualtion
nervous system triggers hormone release
ex: sympathetic nervous system release epinephrine/norepinephrine
Major endocrine glands
Pituitary-anterior/posterior, Pineal Gland
Thyroid, parathyroid- in neck
Adrenal Gland (adrenal cortex/ medulla)-above kidney
Pancreas- behind the stomach
Gonads- ovaries/testes
