HISTOLOGY OF THE MALE RT

Multiple Choice

The area enclosed by the rectangle is known as the:

• Basal compartment

• Adluminal compartment

• Seminiferous epithelium

• Zonula ocludens

Multiple Choice

Which of the following cells manufacture androgen binding protein (ABP)?

• Spermatid

• Sertoli cell

• Peg cell

• Interstitial cell of Leydig

Multiple Choice

Cells that are responsible for the blood-testis barrier are known as:

• Leydig cells

• Sertoli cells

• Interstital cells

• Granulosa cells

Multiple Choice

When these cells are exposed to gonadotropic stimulation, they become androgen-secreting cells and remain active throughout life:

• Adjacent cells

• Sertoli cells

• Leydig cells

• Granulosa cells

Multiple Choice

They represent the first stage in spermatocytogenesis:

• Primary spermatocytes

• Spermatids

• Spermatozoa

• Spermatogonia

Multiple Choice

They are the largest cells at the seminiferous epithelium:

• Secondary spermatocytes

• Primary spermatocytes

• Spermatogonia

• Spermatids

Multiple Choice

This portion of the spermatozoa contains the mitochondria, that provide the energy for the movement of the sperm:

• Head

• Neck

• Middle piece

• Principal piece

Multiple Choice

How long does it take for a spermatogonium produced by a stem cell to complete the process of spermatogenesis?

• 14 days

• 34 days

• 44 days

• 64 days

Multiple Choice

These cells produce glycerophosphocholine, a glycoprotein that inhibits spermatozoa capacitation:

• Tall principal cells

• Short basal cells

• Clear cells

• Sertoli cells

Multiple Choice

This gland produce a yellow, viscous, fructose-rich seminal fluid that constitutes 70% of the volume of semen:

• Prostate

• Testis

• Seminal vesicles

• Bulbourethral gland

Multiple Choice

This zone constitutes 70% of the prostate and contains the main glands, also is the most susceptible site for inflammation and adenocarcinomas:

• Central zone

• Peripheral zone

• Transitional zone

• Anterior zone

Multiple Choice

These glands are located in the root of the penis and produce a viscous fluid that precedes the remainder of the semen:

• Prostate

• Seminal vesicles

• Bulbourethral glands

• Penis glands
