What is the most commonly seen type of epithelium in the prostate?
The glandular epithelium of the prostate is most often simple columnar, however a variety of types can be found.
2 / 25
Which cells are directly involved in spermatogenesis?
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

What type of epithelium lines the epididymis?
Pseudostratified epithelium lines the epididymis.
5 / 25
How many layers of smooth muscle are in the vas deferens?
There are three layers of smooth muscle in the vas deferens. There is an inner longitudinal, a middle circular, and an outer longitudinal.

How many seminiferous tubules are found in each testis of an average man?
The average testis in an adult man has between 400 and 600 seminiferous tubules.
8 / 25
What type of gland composes the prostate?
The prostate is made of compound tuboloalveolar glands.
9 / 25
What gland in the male is homologous to the greater vestibular gland in the female?
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
10 / 25
Which of the following are produced by the Sertoli cells?
Sertoli cells produce inhibin and androgen-binding protein. The interstitial cells of Leydig produce testosterone
11 / 25
Which one of the following are the earliest cells of spermatogenesis?
The earliest cells of spermatogenesis are spermatogonia; these are primitive cells. The primary spermatocyte is derived from spermatogonia. This then develops into secondary spermatocytes . The secondary spermatocyte is haploid. These develop into spermatids. The mature sperm cell is spermatozoa.
12 / 25
Which of the following is NOT considered part of the male genital duct system?
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
13 / 25
What is the surface modification seen on the cells of the epididymis?
Stereocilia are very long microvilli. Stereocilia are seen in the epididymis and the hair cells of the ear.
14 / 25
Which of the following is NOT considered an accessory gland?
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.

18 / 25
What is the stroma of the prostate?
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.

What type of epithelium lines the seminal vesicles?
Pseudostratified epithelium lines the seminal vesicles.
20 / 25
What type of epithelium lines the vas deferens?
Pseudostratified epithelium lines the vas deferens.

Sertoli cells produce inhibin and androgen-binding protein. The interstitial cells of Leydig produce testosterone.
22 / 25
What type of hormone is testosterone?
Steroid hormones are cholesterol derivatives. Steroid hormones include testosterone and estradiol.

24 / 25
What is another term for the corpus cavernosum urethrae?
The corpus spongiosum is also called the corpus cavernosum urethrae. The corpora cavernosa and corpus spongiosum are erectile tissue. The corpus cavernosum clitoridis is in the female. The urethra is a muscular tube that runs from the bladder. It transports both urine and semen.
