Question | Answer |
---|---|
organs whose primary function is the secretion of hormones | primary endocrine organs |
organs whose secretion of hormones is secondary to another function | secondary endocrine organs |
a region in the base of the brain that regulates autonomic functions and secretes several hormones, most of which regulate secretory activity of the pituitary gland | hypothalamus |
primary endocrine gland connected to the hypothalamus at the base of the brain | pituitary gland |
The posterior pituitary gland secretes two peptide hormones. What are they? | ADH (antidiuretic hormone) and Oxytocin |
hormones that regulate the secretion of hormones | tropic hormones |
__________ hormone increases the secretion of another hormone. | Stimulating |
_________ hormone decreases the secretion of another hormone. | Inhibiting |
primary endocrine gland located in the brain; secretes the hormone melatonin | pineal gland |
butterfly-shaped primary endocrine gland located from the hypothalamus that stimulates secretion of TSH from the anterior pituitary | thyroid gland |
primary endocrine gland located near the heart; secretes the hormone thymosin; also is site of T lymphocyte maturation | thymus |
primary endocrine gland located above the kidneys; divided into an outer cortex and an inner medulla | adrenal glands |
outer portion of the adrenal gland; secretes adrenocorticosteroids | adrenal cortex |
steroid hormones secreted from the adrenal cortex | adrenalcorticoids |
steroid hormones secreted from the adrenal cortex that regulate sodium reabsorbtion and potassium secretion by the kidneys; ex. aldosterone | mineralocorticoids |
steroid hormones secreted from the adrenal cortex that regulate the body's response to stress, regulate protein, carbohydrate, and lipid metabolism in a variety of tissues, and regulate blood glucose levels; ex. cortisol | glucocorticoids |
steroid hormones including estrogens, progesterone, and androgens secreted from the adrenal cortex and gonads that regulate reproductive function, promote gametogenesis, growth and maintenance of reproductive organs. | sex hormones |
inner portion of the adrenal gland; secretes catecholamines | adrenal medulla |
a gland located in the abdominal cavity that performs endocrine and exocrine functions; secretes pancreatic juices and hormones, including insulin and glucagon | pancreas |
in endocrine system, when one hormone opposes the actions of another hormone | antagonism |
in the endocrine system, indicates that the effect of two hormones is simply the sum of the effects of each hormone | additive |
pertaining to a process in which the net effect is greater than the sum of the individual effects | synergistic |
phenomenon in which one hormone is needed for another hormone to exert its actions | permissiveness |
