Which of the following is not true of the pineal gland?
Its receptor is in the nucleus of the target organ cell
Which of the following is true of a steroid hormone?
They function like steroid hormones because they stimulate protein synthesis
Which of the following statements is not true of prostaglandins?
cyclic AMP
a second messenger for some hormones
aldosterone
an example of a mineralocorticoid
luteinizing hormone
an increase in the level of this hormone causes ovulation
follicle-stimulating hormone
begins the development of an egg in the ovary
prostaglandin
can be called a "tissue hormone"
target organ cell
has a receptor for a specific hormone
negative feedback
hormone regulating system that tries to return the body to homeostasis
positive feedback
hormone regulation that moves the body farther away from homeostasis
nonsteroid hormone
hormone that requires a second messenger
growth hormone
hypersecretion of this hormone causes acromegaly
parathyroid hormone
increases the level of calcium in the blood
melatonin
made in the pineal gland and affects the biological clock
thymosin
plays an important role in the development and functioning of the immune system
ACTH
produced in the pituitary gland and stimulates the release of hormones from the adrenal cortex
steroid hormone
receptor site for this type of hormone is inside the nucleus of the cell
calcitonin
reduces the level of calcium in the blood
glucocorticoid
released by the adrenal cortex, increases the glucose level of the blood, and is an antiinflammatory
epinephrine
released by the adrenal medulla and reinforces the effects of the sympathetic nervous system
glucagon
released by the pancreatic islet cells and increases the level of glucose in the blood
insulin
released by the pancreatic islets and causes a drop in the blood sugar level
ADH
released by the posterior pituitary and increases water retention in the body
endocrine gland
releases hormones into the interstitial fluid or the blood
exocrine gland
releases its products into ducts leading to the body surface or a body cavity
oxytocin
stimulates muscle contraction in the pregnant uterus and brings about labor
triiodothyronine
thyroid hormone that contains three atoms of iodine
glucagon and insulin
what are antagonists of each other
ACTH
what causes the ovary to begin forming an egg follicle
