Chapter 18: Endocrine System: Vocabulary Flashcards
adrenal cortex
Outer section (cortex) of each adrenal gland. Secretes: - corisol - aldosterone - sex hormones
adrenal medulla
Inner section (medulla) of each adrenal gland.
Secretes:
- epinephrine
- norepinephrine
ovaries
Located in the lower abdomen of a female. Responsible for egg production and secretion of estrogen and progesterone
pancreas
Located behind the stomach. Islet (alpha and beta) cells (islets of Langerhans) secrete hormones from the pancreas. Also contains cells that are exocrine in function. They secrete enzymes, via a duct, into the small intestine to aid digestion
parathyroid glands
Four 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 (2) 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, triiodothyrnine, and calcitonin
adrenaline
epinephrine
Secreted by the adrenal medulla; increases heart rate and blood pressure
adrenocorticotropic hormone
Secreted by the anterior lobe of the pituitary gland. Stimulates the adrenal cortex
aldosterone
Secreted by the adrenal cortex; increases salt (sodium) reabsorption
androgen
Male hormone secreted by the testes and to a lesser extent by the adrenal cortex
antidiuretic hormone
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; increases blood sugar. It is secreted in times of stress and has an anti-inflammatory effect
epinephrine
adrenaline
Secreted by the adrenal medulla; increases heart rate and blood pressure and dilates airways
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
