What kind of follicle does an oocyte mature from?

Question

(This is a question concerning the Reproductive System in Animals).

Answer 1

from the primary follicle

Answer 2

Hi Nishi,

Each follicle contains one egg which is surrounded by layers of follicle cells. These are within the ovaries and are known to produce the female s*x hormones such as estrogen [gives females primary female characteristics]. The follicle cells provide the developing egg the right nutrients and protects it til it matures and leaves the ovaries for [possible] fertizilation.

The ovum in the female reproductive system is made from the secondary oocyte. The secondary oocyte is made from the primary oocyte - the difference between the two oocytes is that the Primary Oocyte has just undergone meiosis I and it starts meiosis II. The Secondary Oocyte forms a polar body at the end of its development from meiosis II.

The Primary Oocyte comes from an Oogenium, this cell is the cell that undergoes mitosis prior to forming a single oocyte [human females form only one egg a month, whereas in males a single cell undergoes mitosis prior to meiosis to form 4 gametes].

Recap:

Oogenium forms a Primary Oocyte, which forms into a Secondary Oocyte which then matures into an Ovum.

Hope this helps you out. Good luck.
