Ques. 1NEET 2016 (Phase 1)

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.

Answer

(4) the ovum and sperms are transported simultaneously to ampullary-isthmic junction of the Fallopian tube.

Solution

As per NCERT, fertilisation can occur only if the ovum and sperms are transported simultaneously to the ampullary-isthmic junction of the Fallopian tube (oviduct).

⇒ The cervix has no ampullary-isthmic junction, and fertilisation does not take place in the uterus or vagina.

Ques. 2NEET 2016 (Phase 1)

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.
Ques. 3NEET 2016 (Phase 1)

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
