endocrine Flashcards
endo,krino means
within, secrete
a chemical messenger
hormones
hormon means.
to set motion
chemical categories: non polar and located in nucleus or cytoplasm
lipid soluble hormones
chemical categories:polar located in plasma membrane
water soluble hormones
stimulation of hormone release: for normal concentrations, stimulate release of some hormones(blood borne)
humoral stimuli
stimulation of hormone release: will allow stimulation of the gland to release hormone
neural stimuli
stimulation of hormone release: prevents secretion of other hormones and called tropic hormones
hormonal stimuli
endocrine glands and their hormones: a small gland about the size of pea
pituitary gland
endocrine glands and their hormones: one of the largesr endocrine glands, secretion of thyroid hormones
thyroid gland
thyroid gland: lack of thyroid hormones
hypothyroidism
thyroid gland: elevated rate of thyroid hormones
hyperthyroidism
endocrine glands and their hormones: these glands secrete the pth which is essential in regulation of calcium level
parathyroid gland
parathyroid gland: low rate of PTH results from injury
hypoparathyroidism
parathyroid gland: elevated rate of PTH causes softening
hyperparathyroidism
endocrine glands and their hormones: two small glands located in superior to each kidney
adrenal gland
endocrine glands and their hormones: the principal hormone relase by the adrenal of norepinephrine
adrenal medulla
endocrine glands and their hormones: have unique structural and functional
adrenal cortex
3 classes of steroid hormones: regulates blood volume and levels of potassium and sodium major hormone is aldosterone
mineralocorticoids
3 classes:regulates blood nutrient levels
glucocorticoids
3 classes: stimulate the development of male sexual
gonadocoticoids
endocrine glands and their hormones: blood glucose has essentioal role in maintaining homeostasis
pancreas
types of pancreas: released beta cells
insulin
occurs when too little insulin is secreted from the pancreas
type 1 diabetes mellitus
occurs when lack of number of insulin
type 2 diabetes mellitus
types of pancreas: released alpha cells
glucagon
release into blood stream
glucose
types of pancreas: released beta delta cells
somatostatin
endocrine glands and their hormones: structure of reproductive tract
testes and ovaries
endocrine glands and their hormones:function the immunity
thymus
endocrine glands and their hormones: produces hormone melatonin which decrease secretion of LH and FSH
pineal gland
