med term chp. 18 Flashcards
adrenal cortex
outer section of a gland above each kidney: secretes cortiso: aldosterone. and sex hormones
adrenal medulla
inner section of a gland above each kidney; secretes epinephrine
ovaries
located in the lower abdomen of a female; responsible for egg cell production and estrogen secretion
pancreas
located behind the stomach; alpha and beta islet cells secrete hormones
parathyroid glands
four small glands on the posterior side of the thyroid gland
pituitary gland
located at the base of the brain in the sella turcica; hypophysis
testes
two glands enclosed in the scrotal sac of a male
thyroid gland
located in the neck oin either side of the trachea; secretes thyroxine
adrenaline (epinephrine)
secreted by the adrenal medulla; increases heart rate and bp
adrenocoritotropic hormone (ACTH)
secreted by the anterior lobe of the pituitary gland; stimulates secretions of the adrenal cortex
aldostreone
secreted by the adrenal cortex; increases salt reabsorption
androgen
male hormone secreted by the testes
antidiuretic hormone (ADH)
secreted by the posterior lobe of the pituitary gland; vasopressin
calcitonin
secreted by the thyroid gland; decreases blood calcium lvls
cortisol
secreted by the adrema; cortex; increases blood sugar
estradiol
female hornome secreted by ovaries
follicle-stimulating hormone
secreted by the anterior lobe of the pituitary gland; stimulates hormone secretion and egg production by the ovaries
glucagon
secreted by the pancreas, increases blood sugar by conversion of glycogen to glucose
growth hormone (somatotropin)
secreted by the anterior lobe of the pituitary gland; stimulates growth of bones and soft tissues
insulin
secreted by beta islet cells of the pancreas; lowers blood sugar
luteinizing hormone
secreted by the anterior lobe of the pituitary gland; stimulates ovulation
oxytocin
secreted by the posterior lobe of the pituitary gland; stimulates contraction of the uterus during childbirth
parahormone
secreted by the parathyroid glands; increases blood calcium
prolactin
secreted by the anterior lobe of the pituitary gland; promotes milk secretion
testosterone
male hormone secreted by the testes
thyroid-stimulating hormone
secreted by the anterior lobe of the pituitary gland; stimulates secretion by the thyroid gland
progesterone
secreted by the ovaries; prepares the uterus for pregnancy
thyroxine
secreted by the thyroid gland; increases metabolism in cells; T4
catecholamines
hormones derived from an amino acid and secreted by the adrenal medulla
corticosteroids
steroid hormones secreted by the adrenal cortex; cortisol, aldosterone, and sex hormones are examples
electrolyte
mineral salt found I nthe blood and tissues and necessary for proper functioning of cells; potassium is an example
homeostasis
tendency of an organism to maintain a constant internal enviornmenthy
hypothalamus
region of the brain lying below the thalamus; secretes factors and hormones that affect the pituitary gland
glucocorticoid
steroid hormone secreted by the adrenal cortex;regulates glucose, fat, and protein metabolism
mineralocorticoid
steroid hormone secreted by the adrenal cortexl regulates mineral salts and water balance
sella turcica
cavity in the skull that contains the pituitary gland
sympathomimetic
mimicking or copying the effect of the sympathetic nervous system; adrenaline is an example
target tissue
cells of an organ that are affected or stimulated by specific hormones
