A temporary endocrine gland in the human body is

  1. corpus cardiacum
  2. corpus luteum
  3. corpus allatum
  4. pineal gland.

Answer

(2) corpus luteum

Solution

As per NCERT, after ovulation the remaining parts of the Graafian follicle transform into the corpus luteum, which secretes large amounts of progesterone. In the absence of fertilisation it degenerates.

∴ The corpus luteum is a temporary endocrine gland.

Corpus cardiacum and corpus allatum are endocrine glands of insects; the pineal gland is a permanent gland.

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'.
