Labia majora
Labia minora
Mons pubis - Answer -Labia majora
The SRY gene of the Y chromosome codes for the protein, ________, which initiates
the development of the testes. At 8-9 weeks, _______ is secreted to develop the
mesonephric ducts into the male anatomy.
Testes-determining factor (TDF) and testosterone
Testosterone-determining factor (TDF) and testosterone
Testes-determining factor (TDF) and mullerian, inhibiting factor (MIF)
Testosterone-determining factor (TDF) and mullerian-inhibiting factor (MIF) - Answer -
Testosterone-determining factor and mullerian-inhibiting factor
Give the proper order for the path of a sperm from its initial development to the ductus
(vas) deferens.
Seminiferous tubules > rete testes >ampulla > epididymis > ductus deferens
Seminiferous tubules > efferent ductules > rete testes > epididymis > ductus deferens
Rete testes > seminiferous tubules > efferent ductules > epididymis > ductus deferens
Seminiferous tubules > rete testes > efferent ductules > epididymis > ductus deferens -
Answer -Seminiferous tubules > rete testes > efferent ductules > epididymis > ductus
deferens
During the emission stage of male orgasm, _______ signals stimulate peristalsis to
propel sperm through the ducts.
Sympathetic
, Somatic
Parasympathetic
Parasomatic - Answer -Sympathetic
True or False: The absence of androgen hormones (testosterone) is the main factor that
controls the development of the female gonads. - Answer -True
Which of the following structures acts to regulate temperature in the scrotum by relaxing
to suspend the testes further from the body?
Cremaster muscle
Pampiniform plexus
Dartos muscle
Countercurrent heat exchanger - Answer -Cremaster muscle
Spermatogonia undergo mitosis to give rise to Type A and Type B daughter cells.
Which of the following is a true statement about Type B daughter cells?
They are lost as polar bodies
They are destined to become sperm
They are Haploid (1n)
They maintain the germ line of spermatogonia - Answer -They are destined to become
spem
Put the following steps of spermatogenesis in the correct order:
Type A daughter cell > growth > primary spermatocyte > meiosis I > secondary
spermatocyte > meiosis II > spermatids
Type B daughter cell > meiosis I > growth > primary spermatocyte > secondary
spermatocyte > meiosis II > spermatids
Type B daughter cell > growth > primary spermatocyte > meiosis I > secondary
spermatocyte > meiosis II > spermatids
Type A daughter cell > meiosis I > primary spermatocyte > meiosis I > secondary
spermatocyte > meiosis II > spermatids - Answer -Type B daughter cell > growth >
primary spermatocyte > meiosis I > secondary spermatocyte > meiosis II > spermatids
The bulbourethral gland produces which of the following?
Milky secretion that makes up about 30% of semen
Clear slippery secretion that neutralizes acidity of leftover urine in the male urethra
Yellowish secretion that provides sugar to the mitochondria of the sperm
Secretion that provides most of the volume of the semen (about 60%) - Answer -Clear
slippery secretion that neutralizes acidity of leftover urine in the male urethra
After leaving the ductus (vas) deferens sperm travels through the last 3 structures in
what order?
