Which cells produce testosterone?
a. Interstitial cells
b. Leydig cells
c. Sertoli cells
d. Sustentacular cells
e. Both a and b

cells" or "interstitial cells of Leydig". Sertoli cells are directly
involved in spermatogenesis. They are also called "sustentacular cells"
or "nurse cells".

Answer: c
The male genital duct system contains: rete testes, tubuli recti,

5.

e. Both a and b
Answer: b
Microvilli are the finger like projections seen on the surface of some
cells. The appearance of microvilli form what is also called the brush
border or striated border.
Stereocilia are very long microvilli. Stereocilia are seen in the epididymis and the hair cells of the ear.
Cilia is the hair like surface modification seen on some epithelia. Cilia are made of microtubules.
Keratinization is seen in the epidermis. Cells in the stratum corneum are essentially just bags of keratin.

What type of hormone is testosterone?

Answer: c
Hormones can have a variety of structures. Hormones which are proteins
include insulin and prolactin. Peptide chains are short chains of amino
acids. Examples of hormones which are peptide chains are antidiuretic
hormone and oxytocin. Steroid hormones are cholesterol derivatives.
Steroid hormones include testosterone and estradiol. Norepinephrine and
epinephrine are catecholamines.

e. There are four corpora cavernosa and two corpora spongiosum
Answer: c
The corpora cavernosa and corpus spongiosum are erectile tissue. There are two corpora cavernosa and one corpus spongiosum.
8.

d. Cowper's gland
e. Brunner's gland
Answer: d
The prostate gland is found in males.
Skene's glands are also called the lesser vestibular glands and are found in females.
The bulbourethral glands are also called Cowper's glands. The
bulbourethral glands are found in males and are homologous to the
Bartholin's glands in females.
Brunner's glands are found in the duodenum.

a. Pseudostratified
b. Simple columnar
c. Stratified squamous
d. Simple squamous
e. Simple cuboidal
Answer: a

1.
Which cells are directly involved in spermatogenesis?
a. Interstitial cells
b. Leydig cells
c. Sertoli cells
d. Sustentacular cells
e. Both c and d
Answer: e
Leydig cells produce testosterone. These are also called "interstitial
cells" or "interstitial cells of Leydig". Sertoli cells are directly
involved in spermatogenesis. They are also called "sustentacular cells"
or "nurse cells".
2.
Which of the following are produced by the Sertoli cells?
a. Inhibin

c. Seminal vesicles
d. Ductus deferens
e. None of the above
Answer: d
The male genital duct system contains: rete testes, tubuli recti,
ductuli efferentes, ductus epididymidis, and ductus deferens. The male
accessory glands contain the bulbourethral glands, seminal vesicles, and
prostate.
4.

a. Bartholin's gland
b. Prostate gland
c. Skene's gland
d. Cowper's gland
e. Brunner's gland
Answer: d
Bartholin's glands are also called the greater vestibular glands.
Bartholin's glands are found in females and are homologous to the
bulbourethral glands in males.
The prostate gland is found in males.
Skene's glands are also called the lesser vestibular glands and are found in females.
The bulbourethral glands are also called Cowper's glands. The
bulbourethral glands are found in males and are homologous to the
Bartholin's glands in females.

Answer: d
Psammoma bodies are collections of calcium. It is derived from the Greek word "psammos", which means sand.
Corpora arenacea refers to the calcifications seen in the pineal gland. Corpora arenacea is nicknamed "brain sand".
Hassall's corpuscles are the ring like structures found in the thymus.
The spherical structures seen in some prostatic alveoli are called prostatic concretions.
Pacinian corpuscles are pressure receptors in the skin.

7.
What type of epithelium lines the vas deferens?
a. Pseudostratified
b. Simple columnar
c. Stratified squamous
d. Simple squamous
e. Simple cuboidal
Answer: a
Pseudostratified epithelium lines the vas deferens.
8.
What type of gland composes the prostate?
a. Simple straight tubular gland
b. Simple coiled tubular gland
c. Simple alveolar gland
d. Compound tubular gland
e. Compound tubuloalveolar gland
A gland that has a duct that does not branch is called a simple gland. If the duct
branches, it is referred to as a compound gland.
If the the part of the gland which secretes elements is shaped like a tube, it is
referred to as a tubular gland. If the ending of the tube is flasklike, it is
tubuloalveoler. If the part of the gland which secretes elements is
shaped like a flask, it is referred to as acinar or alveolar.
The prostate is made of compound tuboloalveolar glands.
9.
What is the stroma of the prostate?
a. Loose irregular connective tissue
b. Smooth muscle
c. Fibromuscular
d. Adipose tissue
e. Dense irregular connective tissue
Answer: c
The glands of the prostate lie in a fibromuscular stroma. It is also
referred to as a fibroelastic stroma. There are bundles of smooth muscle
within dense irregular connective tissue.
10.

a. 1
b. 2
c. 3
d. 4

Answer: c
There are three layers of smooth muscle in the vas deferens. There is an
