Choose the correct statements:
A. The testes are situated outside the abdominal cavity within a pouch called scrotum.
B. The scrotum keeps the temperature of the testes higher than the normal internal body temperature.
C. The seminiferous tubules of the testis open into the vasa efferentia through rete testis.
D. The bulbourethral glands are paired male accessory glands.
Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → A, C and D only
A. The testes are situated outside the abdominal cavity within a pouch called scrotum. — True. The testes lie outside the abdomen, in the scrotum.
B. The scrotum keeps the temperature of the testes higher than the normal internal body temperature. — False. The scrotum keeps the testes at a lower temperature than the internal body temperature. This low temperature is necessary for spermatogenesis.
C. The seminiferous tubules of the testis open into the vasa efferentia through rete testis. — True. Sperms pass from the seminiferous tubules through the rete testis into the vasa efferentia, and from there into the epididymis.
D. The bulbourethral glands are paired male accessory glands. — True. The male accessory glands are the paired seminal vesicles, a prostate and the paired bulbourethral glands.
So A, C and D are correct.
NCERT Extract:
The Male Reproductive System – “… The testes are situated outside the abdominal cavity within a pouch called scrotum. The scrotum helps in maintaining the low temperature of the testes (2–2.5o C lower than the normal internal body temperature) necessary for spermatogenesis.”
The Male Reproductive System – “… The male sex accessory ducts include rete testis, vasa efferentia, epididymis and vas deferens (Figure 2.1b). The seminiferous tubules of the testis open into the vasa efferentia through rete testis.”
The Male Reproductive System – “… The male accessory glands (Figure 2.1a, b) include paired seminal vesicles, a prostate and paired bulbourethral glands.”
