Cards

Term
Adrenocorticotropic hormone
Definition
Anterior Pituitary

Controls the release of hormones from the adrenal cortex
Term
Thyroid stimulating hormone
Definition
Anterior Pituitary

Controls the secretion of hormones from the thyroid
Term
Growth Hormone
Definition
Anterior Pituitary

Stimulates an increase in the size and rate of reproducing body cells, enhances the movement of amino acids through membrane
Term
Prolactin
Definition
Anterior Pituitary

Stimulates milk production after birth
Term
Luteinizing hormone
Definition
Anterior Pituitary

Promotes the secretion of sex hormones;

Plays a role in releasing an egg cell in females
Term
Follicle-stimulating hormone
Definition
Anterior Pituitary

Responsible for the development of the egg-containing follicles in the ovaries;

stimulates the follicular cells to secrete estrogen; in males, stimulates the production of sex hormones
Term
Antidiuretic hormone
Definition
Posterior Pituitary
Posterior Pituitary

Causes the kidneys to reduce water excretion; in a high concentration, increases the blood pressure
Term
Oxytocin
Definition
Posterior Pituitary

Causes contractions of the muscles in the uterine wall; causes the muscles associated with the milk-secreting glands to contract
Term
Aldosterone
Definition
Adrenal Cortex

Helps regulate the concentration of extracellular electrolytes by causing soduim ions to be conserved and potassium ions to be excreted
Term
Cortisol
Definition
Adrenal Cortex

Decreases protein synthesis; increases fatty acid release, and stimulates the formation of glucose from non-carbohydrates
Term
Adrenal androgens
Definition
Adrenal Cortex

Supplement the sex hormones from the gonads; converted to estrogens in females
Term
Norepinephrine
Definition
Adrenal Medulla

Sympathetic nervous system

Included increased heart-rate and increased force of cardiac muscle contraction, elevated blood pressure, increased breathing rate, and decreased activity in the digestive system
Term
Epinephrine
Definition
Adrenal Medulla

regulating heart rate, blood vessel and air passage diameters, and metabolic shifts; crucial component of the fight-or-flight response of the sympathetic nervous system
Term
Thymosin
Definition
Thymus

Affects the production and differentiation of white blood cells (lymphocytes)
Term
Thyroxine
Definition
Thyroid

Helps regulate the metabolism of carbohydrates, lipids, and enhance the rate of protein synthesis; essential to the maturation of the nervous system
Term
Calcitonin
Definition
Lowers the blood calcium and phosphate concentrations by inhibiting the release of calcium and phosphate ions from bones and by increasing the excretion of these ions by the kidneys
Term
Parathyroid hormone
Definition
Parathyroid

Causes an increase in the blood calcium concentration and a decrease in the blood phosphate concentration
Term
Insulin
Definition
Pancreas

Acts on the liver to convert glycogen and certain noncarbohydrates such as amino acids into glucose causing the blood glucose concentration to rise.
Term
Glucagon
Definition
Pancreas

Stimulates the liver to convert glycogen and certain noncarbohydrates such as amino acids into glucose causing the blood glucose concentration to rise
Term
Melatonin
Definition
Pineal gland

Affects the secretion of gonadotropic hormones
-Regulates the female reproductive cycle
-Night and day cycle
Term
Gastrin
Definition
Stomach

Stimulates acid secretion
Term
Atrial natriuretic hormone
Definition
Heart

Promotes the excretion of sodium ions in the urine
Term
Erythropoietin
Definition
Kidney

Stimulates red blood cell production
Term
1, 25 Dihydrooxyvitamin D3
Definition
Skin

Stimulates bile and pancreatic juice secretion
Term
Secretin (cholecystokinin)
Definition
Small Intestine

Inhibits gastric motility;

Stimulates bile and pancreatic juice secretion
Term
Progesterone (placenta)
Definition
Placenta

Helps maintain the uterus in tis pregnant state and prevents spontaneous abortion
Term
Testosterone
Definition
Testes

Stimulates secondary sexual development
Term
Releasing and inhibiting hormones
Definition
Hypothalmus

Regulates secretion of anterior pituitary hormones
Term
Estrogen
Definition
Ovaries

Development and maintenance of the female secondary sexual characteristics
Term
Progesterone (Ovaries)
Definition
Ovaries

Promotes the changes that occur in the uterus during the female reproductive cycles
