Chapter 11 Review
These molecules affect the organ in which they are
produced?
a. Steroid hormones
b. Peptide hormones
c. Prostaglandins
d. Amino acids
Their effects include: relaxing/contracting smooth
muscles of the air ways and blood vessels, secretion
of other hormones, influence of blood pressure, and
inflammation.
These 2 hormones stimulate the gonads
(ovaries/testes) to mature:
a. Testosterone and progesterone
b. TSH & ACTH
c. GH & prolactin
d. FSH & LH
FSH- follicle stimulating hormone
LH- leuteinizing hormone
Both target the ovaries (stimulate the production of
estrogen and progesterone) and testes (stimulate the
production of testosterone).
Testosterone is needed for the development of:
a. Eggs
b. Sperm
c. Uterine lining
d. All of the above
Testosterone is a steroid based hormone produced by
the testes and is important in sperm development and
secondary sex characteristics.
Growth hormone
a. Promotes the movement of amino acids into cells
b. Increases the rate of cell division
c. Increases the rate of fat metabolism
d. All of the above
Growth hormone is released by which gland?
Anterior Pituitary Gland
The secretion of hormones from the anterior lobe
of the pituitary gland is controlled by
a. Releasing hormones from the hypothalamus
b. Releasing factors from the thalamus
c. Nerve impulses from the hypothalamus
d. Nerve impulses from the thalamus
The hypothalamus (Master gland) is the link between
the nervous & endocrine systems; it controls the
Anterior Pituitary Gland.
Hypothalamus
Anterior
Pituitary
To other glands
Hormones released by the hypothalamus include:
Releasing hormones- to promote hormone production
from the anterior pituitary gland
Inhibiting hormones -these prevent hormone production
from the anterior pituitary gland
The endocrine system is made up of
a. Hormones
b. Glands
c. Gonads
d. Prostaglandins
The endocrine system
a. Affects only the reproductive system
b. Releases hormones into the bloodstream
c. Competes with the nervous system
d. Is made up primarily of glands with ducts
It is NOT “d” because… exocrine glands secrete
through ducts NOT endocrine glands.
What is the function of the pancreas?
a. To produce sex hormones
b. To produce thyroxine
c. To produce insulin and glucagon
d. To produce thymosin
Which gland produces epinephrine (adrenaline) and
norepinephrine (noradrenalin)?
a. Parathyroid
b. Hypothalamus
c. Pituitary
d. Adrenal
Which gland fails to produce enough of its
hormone in the disease diabetes mellitus?
a. Adrenal
b. Hypothalamus
c. Pancreas
d. Parathyroid
Feedback inhibition means that an increase in a
substance will
a. Decrease production of that substance
b. Increase production of that substance
c. Increase the production of other substances
d. Stop production of another substance
One way the endocrine system helps maintain
homeostasis is by having
a. Each gland secrete only one hormone
b. Two hormones with opposite effects regulate
certain functions
c. Only steroid hormones regulate important
functions
d. The pituitary gland regulates all the other
glands
Which gland regulates circadian rhythms?
a. Pancreas
b. Parathyroid
c. Pineal
d. Thyroid
Name the male gonads:
Testis
Name the female gonads:
Ovaries
Know the location
of the
glands.
1. Steroid hormones
can pass through the
cells membrane
because?
A: They are lipid soluble.
2. The hormone receptor
for steroid hormones is
located in the cells?
1.
3.
A: Nucleus
3. A steroid hormone
promotes?
A: Protein synthesis
2.
1. Non-steroid hormones
are made of?
1.
A: Amino acids
2. The hormone-receptor
complex for non-steroid
hormones is located in the
cells…
A: membrane
3. A non-steroid hormone
uses a _____ (called
___) to activate changes
within the cytoplasm.
A: second messenger:
cAMP
