Human Reproductive System Questions
-
Transformation of spermatids into spermatozoa
-
Formation of ova in the Graafian follicles of ovary
-
Differentiation of cells at specific locations of the germ layers of gastrula to form the organ rudiments
-
Release of sperms from seminiferous tubules
-
Release of ova from Graafian follicle
D
Correct answer
Explanation
Release of sperms from the seminiferous tubules is called spermiation.
-
deficit of formation of a testis
-
breast development in human males at puberty
-
deficit of virilization of the phallus
-
presence of a uterus
D
Correct answer
Explanation
Mullerian-inhibiting substance prevents development of Mullerian ducts into a uterus and fallopian tubes. Absence of the substance would lead to persistence of these structures in a male.
-
IVF minimises the chances of a couple conceiving quickly.
-
Useful in cases of poor sperm quality and motility or low sperm counts.
-
Useful in embryo transfer.
-

A
Correct answer
Explanation
It maximises the chances of a couple conceiving quickly.

-
sustentacular cells
-
interstitial cells
-
ductus deferens
-
epididymis
A
Correct answer
Explanation
These cells assist with sperm development provide a protective environment, and create a barrier between sperm cells and the circulatory system.
-

-
testisitis
-
orchitis
-
otitis media
C
Correct answer
Explanation
It is the inflammation of one or both testes. It may be caused by sexually transmitted diseases (STD), such as gonorrhea or chlamydia.
-
primordial follicles
-
primary follicle
-
secondary follicle
-
vesicular follicle
A
Correct answer
Explanation
Primordial follicles are indiscernible to the naked eye. However, these eventually develop into primary, secondary and tertiary vesicular follicles.They accommodate a primary oocyte and several layers of follicle cells.
-
Sertoli cells
-
Myoid cells
-
Leydig cells
-
Stem cell
B
Correct answer
Explanation
Each seminiferous tubule is enclosed by a thin layer of contractile myoid cells, which produce waves of contraction to propel immature and immotile spermatozoa out of the testis.
-
crus
-
corpus cavernosum
-
hood
-
glans
B
Correct answer

-
The navicular fossa
-
Tunica dartos
-
Cremaster
-
Perineal raphe
C
Correct answer
Explanation
