Which of the following is least descriptive of the hypothalamus?
secretes ACTH, TSH, and gonadotropins
T3, T4, and calcitonin are
secreted by the thyroid gland.
Insulin and glucagon
are secreted by the pancreas and are concerned with the regulation of blood glucose.
The islets of Langerhans
secrete insulin and glucagon.
Steroids
include the glucocorticoids, mineralocorticoids, and androgens.
The adrenal medulla
is part of the "fight-or-flight" response.
Iodine containing hormones
regulate metabolic rate.
Antidiuretic hormone (ADH) and oxytocin
stimulate the kidney to excrete Na+ and water.
Portal capillaries carry releasing hormones from the brain to the
anterior pituitary gland.
Which of the following is the response to low plasma levels of calcium?
secretion of PTH
What is the stimulus for the release of insulin?
high plasma levels of glucose
The adenohypophysis
refers to the anterior pituitary gland
This gland secretes TSH, ACTH, and growth hormone.
anterior pituitary gland
The adrenal cortex
secretes catecholamines
This gland is associated with "sugar, salt, and sex."
adrenal cortex
Which of the following is least associated with the adrenal medulla?
sugar, salt sex
Catecholamines
include epinephrine (adrenaline) and norepinephrine
Enlargement of the thyroid gland
goiter
"Sugar, salt, and sex" is descriptive of
cortisol, aldosterone, testosterone
Insulin, cortisol, thyroxine, and oxytocin
are hormones
Lactogenic hormone
stimulates the mammary glands to make milk
Which of the following is not controlled by a hypothalamic-releasing hormone?
ADH
Growth hormone
is secreted by the adenohypophysis
stimulates growth of the musculoskeletal system
is also called somatotropic hormone
(all the above)
Estrogen, progesterone, and testosterone
are secreted by the gonads
Testosterone is best described as
adenohypophyseal
Calcitonin and parathyroid hormone
control plasma levels of calium
Which of the following structures connects the hypothalamus and the adenohypophysis
portal capillaries
Which of the following hormones are found within the hypophyseal hypothalamic portal capillaries?
releasing hormones
A deficiency of insulin causes
hyperglycemia
Oxytocin
is a neurohypophyseal hormone that stimulates the uterine muscle to contract, thereby assisting in labor.
Which of the following is most descriptive of cAMP?
second chemical messenger
TSH
is secreted by the anterior pituitary gland
The only hormone that lowers blood glucose is
insulin
PTH
stimulates osteoblastic activity and causes blood calcium to increase
Insulin
is secreted by the beta cells of the islets of Langerhans
ACTH stimulates the
adrenal cortex to secrete cortisol.
The secretion of cortisol by the adrenal gland suppresses further secretion of ACTH by the anterior pituitary gland. What is this interaction called?
negative feedback control
Which of the following steroids is an androgen?
testosterone
Which of the following is a function of parathyroid hormone?
It increases plasma levels of calcium
Cretinism, myxedema, and Graves' disease are all
thyroid hormone-deficiency diseases.
Hypocalcemic tetany
resembles neuromuscular blockade by curare
The neurohypophysis
posterior pituitary gland
What is the most likely effect of a deficiency of aldosterone?
