Select the correct sequence for transport of sperm cells in male reproductive system :

  1. Seminiferous tubules Vasa efferentia Epididymis Inguinal canal Urethra
  2. Testis Epididymis Vasa efferentia Vas deferens Ejaculatory duct Inguinal canal Urethra Urethral meatus
  3. Testis Epididymis Vasa efferentia Rete testis Inguinal canal Urethra
  4. Seminiferous tubules Rete testis Vasa efferentia Epididymis Vas deferens Ejaculatory duct Urethra Urethral meatus

Answer

(4) Seminiferous tubules Rete testis Vasa efferentia Epididymis Vas deferens Ejaculatory duct Urethra Urethral meatus

Solution

As per NCERT, the seminiferous tubules of the testis open into the vasa efferentia through the rete testis.

⇒ The vasa efferentia open into the epididymis, which leads to the vas deferens.

⇒ The vas deferens ascends to the abdomen, loops over the urinary bladder and joins the duct of the seminal vesicle to form the ejaculatory duct, which opens into the urethra.

⇒ The urethra opens to the outside through the urethral meatus.

∴ Seminiferous tubules → Rete testis → Vasa efferentia → Epididymis → Vas deferens → Ejaculatory duct → Urethra → Urethral meatus

Fertilisation in humans is practically feasible only if

  1. the ovum and sperms are transported simultaneously to ampullary-isthmic junction of the cervix
  2. the sperms are transported into cervix within 48 hrs of release of ovum in uterus
  3. the sperms are transported into vagina just after the release of ovum in Fallopian tube
  4. the ovum and sperms are transported simultaneously to ampullary-isthmic junction of the Fallopian tube.

Select the incorrect statement.

  1. LH and FSH decrease gradually during the follicular phase.
  2. LH triggers secretion of androgen from the Leydig cells.
  3. FSH stimulates the Sertoli cells which help in spermiogenesis.
  4. LH triggers ovulation in ovary.

Identify the correct statement on 'inhibin'.

  1. Is produced by granulosa cells in ovary and inhibits the secretion of LH
  2. Is produced by nurse cells in testes and inhibits the secretion of LH
  3. Inhibits the secretion of LH, FSH and prolactin
  4. Is produced by granulosa cells in ovary and inhibits the secretion of FSH
