antibodies
b)
proteins
c)
hormones
d)
enzymes
4.
Oxytocin
a)
exerts its most important effects during menstruation
b)
controls milk production
c)
is an adenohypophyseal secretion
d)
release is an example of a positive feedback control mechanism
5.
Gonadocorticoid(s)
a)
synthesized by the adrenal medulla are primarily androgens
b)
hypersecretion can result in adrenogenital syndrome, also called feminization
c)
production by the adrenal gland is insignificant compared with sex hormone release from the gonads during late puberty
d)
secretion inhibition is highly dependent on a negative feedback loop involving ACTH
6.
The ability of a specific tissue or organ to respond to the presence of a hormone is dependent on
a)
the membrane potential of the cells of the target organ
b)
the location of the tissue or organ with respect to the circulatory path
c)
nothing- all hormones of the human body are able to stimulate any and all cell tpes because hormones are powerful and nonspecific
d)
the presence of the appropriate receptors on the cells of the target tissue or organ
7.
Several hormones are synthesized in the hypothalamus and transported to the anterior pituitary gland. the mechanism of transportation from hypothalamus to anterior pituitary gland is through the
a)
feedback loop
b)
general circulatory system
c)
hepatic portal system
d)
hypophyseal portal system
8.
The second messenger mechanism of hormone action operates by
a)
not responding to a feedback mechanism
b)
increasing the basal metabolic rate in the target organ
c)
synthesizing more of the hormone than is usually needed
d)
binding to specific receptors and employing the services of G proteins and cAMP
9.
When it becomes necessary to enlist the fight-or-flight response, a hormone that s released during the alarm phase of the general adaptation syndrome is
a)
epinephrine
b)
renin
c)
angiotensinogen

the blood vessels
b)
the adrenal glands
c)
bones and skeletal muscles
d)
the liver
11.
A man has been told that he is not synthesizing enough follicle-stimulating hormone (FSH), and for this reason he may be unable to father a child. Chose the correct statement to explain this problem
a)
FSH stimulates estrogen secretion by ovarian cells; therefore it is not synthesized by males
b)
the man must be producing progesterone, which inhibits the synthesis of FSH
c)
the physician is wrong- a hormone made in the adenohypophysis could not influence fertility
d)
FSH stimulates sperm production in the testes
12.

humoral stimulation
d)
protein synthesis

a)
It controls ALL body processes
b)
Hypothalamus generates hormones and stores them into the pituitary
c)
