Question:
which of the following is correct withrespect to antrum ?
Options:
The secondary follicle soon transforms into a tertiary follicle which is characterised by a fluid filled cavity.
It is an unequal division resulting in the formation of a large haploid secondary oocyte.
The tertiary follicle further changes into the mature follicle.
The Graafian follicle now ruptures to release the secondary oocyte (ovum).
Correct Answer:
The secondary follicle soon transforms into a tertiary follicle which is characterised by a fluid filled cavity.
Explanation:
During oogenesis, each primary oocyte gets surrounded by a layer of granulosa cells and then called as the primary follicle. The primary follicles get surrounded by more layers of granulosa cells and a new theca and called as secondary follicles. The secondary follicle soon transforms into a mature tertiary follicle or Graafian follicle, which is characterized by a fluid-filled cavity, called as antrum.
