Chp 18- Endocrine System Flashcards
adrenal cortex
outer section of each adrenal gland; secretes cortisol, aldosterone, and sex hormones
adrenal medulla
inner section of each adrenal gland; secretes epinephrine and norepinephrine
ovaries
located in lower abdomen of female, egg production and estrogen/progesterone secretion
pancreas
located behind the stomach
parathyroid gland
4 small glands on the posterior of the thyroid gland
pituitary gland (hypophysis)
located at the base of the brain in the sella turcica
testes
two glands enclosed in the scrotal sac of a male; responsible for sperm production and testosterone secretion
thyroid gland
located in the neck on either side of the trachea; secretes thyroxine, triiodothyronine, and calcitonin
adrenaline/ epinephrine
secreted by medulla; increases HR and BP
Adrenocorticotropic hormone (ACTH)
secreted by the anterior lobe of the pituitary gland; stimulates adrenal cortex
aldosterone
secreted by the adrenal cortex; increases salt absorption
androgen
male hormone secreted by the testes and adrenal cortex
antidiuretic hormone (ADH)
secreted by the posterior lobe of the pituitary gland; increases reabsorption of water by the kidneys
calcitonin
secreted by the thyroid gland; decreases blood calcium levels
cortisol
secreted by the adrenal cortex; increases blood sugar
estradiol
estrogen secreted by the ovaries
estrogen
female hormone secreted by the ovaries and adrenal cortex
Follicle stimulating hormone (FSH)
Secreted by the anterior lobe of the
pituitary gland; stimulates hormone
secretion and egg production by ovaries
and sperm production by testes
glucagons
Secreted by alpha islet cells of pancreas;
increases blood sugar
growth
hormone (GH);
somatotropin
Secreted by the anterior lobe of the
pituitary gland; stimulates growth of
bones and soft tissues
insulin
Secreted by beta islet cells of pancreas;
helps glucose pass into cells and promotes
conversion of glucose to glycogen
luteinizing
hormone (LH)
Secreted by the anterior lobe of 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
uterus during labor and childbirth
parathormone
(PTH)
Secreted by 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 testes
Thyroid-stimulating hormone (TSH); Thyrotropin
secreted by the anterior lobe of the pituitary gland; promotes milk secretion
somatotropin (STH)
secreted by the anterior lobe of the pituitary gland; promotes thyroid function
thyroxine (T4)
secreted by the thyroid gland; increases cell metabolism
Triiodothyronine (T3)
secreted by the thyroid gland; increases cell metablisom
vasopressin
secreted by the posterior lobe of the pituitary gland; ADH; raises water reabsorption and raises BP
catecholamines
hormones derived from an amino acid and secreted by the adrenal medulla
corticosteroids
hormones produced by the adrenal cortex
