Chapter 18 Hormones Flashcards
adrenaline (epinephrine)
secreted by the adrenal medulla; increases heart rate and blood pressure
adrenocorticotropic hormone (ACTH)
secreted by the anterior lobe of the pituitary gland; stimulates the adrenal cortex
aldosterone
secreted by the adrenal cortex; increases salt reabsorption
androgen
male hormone secreted by the testes and to a lesser extend by the adrenal cortex; testosterone is an example
antidiuretic hormone (ADH)
secreted by the posterior lobe of the pituitary gland; increases reabsorption of water by the kidney
calcitonin
secreted by the thyroid gland; decreases blood calcium levels
cortisol
secreted by the adrenal cortex in times of stress and has an anti-inflammatory effect; increases blood sugar
epinephrine (adrenaline)
secreted by the adrenal medulla; increases heart rate and blood pressure and dilates airways “fight or flight”
estradiol
estrogen (female hormone) secreted by the ovaries
estrogen
female hormone secreted by the ovaries and to a lesser extent by the adrenal cortex
follicle-stimulating hormone
secreted by the anterior lobe of the pituitary gland; stimulates hormone secretion and egg production by the ovaries and sperm production by the testes
glucagon
secreted by the alpha islet cells of the pancreas; increases blood sugar by conversion of glycogen (starch) to glucose
growth hormone (GH); somatotropin
secreted by the anterior lobe of the pituitary gland; stimulates growth of bones and soft tissue
insulin
secreted by beta islet cells of the pancreas; helps glucose pass into cells and promotes conversion of glucose to glycogen
luteinizing hormone (LH)
secreted by the anterior lobe of the pituitary gland; stimulates ovulation in females and testosterone secretion in males
norepinephrine
secreted by the adrenal medulla; increases heart rate and blood pressure
oxytocin (OT)
secreted by the posterior lobe of the pituitary gland; stimulates contraction of the uterus during childbirth
parathormone (PTH)
secreted by the parathyroid glands; increases blood calcium
progesterone
secreted by the ovaries; prepares the uterus for pregnancy
prolactin (PRL)
secreted by the anterior lobe of the pituitary gland; promotes milk secretion
somatotropin (STH)
secreted by the anterior lobe of the pituitary gland; growth hormone
testosterone
male hormone secreted by the testes
thyroid-stimulating hormone (TSH); thyrotropin
secreted by the anterior lobe of the pituitary gland; acts on the thyroid gland to promote its functioning
thyroxine (T4)
secreted by the thyroid gland; also called tetraiodothyronine; increases metabolism in cells
triiodothyronine (T3)
secreted by the thyroid gland; increases metabolism in cells
vasopressin
secreted by the posterior lobe of the pituitary gland; increases water reabsorption and raises blood pressue
