Answers
The thymus gland secretes hormones called ____ that ____
Thymosins; control production and differentiation of white blood cells
Exocrine glands differ from endocrine gland in that exocrine glands
Secrete through ducts or tubes to the body's exterior
Oxytocin stimulates the kidneys to conserve water
False
The secretion of parathyroid hormone is controlled primarily by the
concentration of blood calcium
A person under stress may have a lowered resistance to infection
True
A hormone is a ____ and the target cell is ____
Molecule that has a metabolic effect on another cell; a cell that has receptors for
specific molecules
The ____ secretes triiodothyronine
Thyroid gland
Choose the example that does not demonstrate a negative feedback loop of
hormonal control
Pressure receptors sense the movement of a baby against and through the cervix
during labor. They stimulate the hypothalamus to release a hormone that causes uterine
contractions. This causes more pressure receptor stimulation, leading to larger releases
of the hormone and stronger, more frequent contractions. Hormone release ceases
after pressure sensation cease
A hormone is a secreted molecule that is carried in the bloodstream to where it
acts on target cells that bear specific receptor for that hormone
True
A female patient is experiencing a hormonal imbalance that is causing her to skip
menstrual periods due to low estrogen and miss ovulation. Which of the following
is most likely the imbalance hormone?
follicle-stimulating hormone
As a result of the general stress response, blood concentrations of epinephrine
And cortisol rise
Secretion of insulin causes
A decrease in the concentration of blood glucose
A sweat gland is an example of a(n) ____ gland
Exocrine

Hypothalamus

Iodine
Steroid hormones diffuse through cell membranes, then bind with receptors,
whereas nonsteroid hormones bind receptors on the target cell membrane
True
The hormone that the pineal gland secretes is
Melatonin
The sex hormones from the adrenal cortex are primarily androgens
True
The target cells of releasing hormones are in the anterior pituitary gland
True
Steroid hormones
Are soluble in lipids

exposure is disturbing their ____, which controls the release of the hormone ____
circadian rhythm; melatonin

blood pressure. He most likely has
A very healthy cardiovascular system
When a person's pulse is taken by palpation near the thumb on the wrist, which
artery is felt?
Radial artery
