Question

The minute cells, which separate from the developing ova during their maturation are called
A. Primary oogonia
B. Secondary oogonia
C. Polar bodies
D. Primary spermatogonia

Answer 1

Hint: Approximately 6 million to 7 million eggs are produced during foetal life. No fresh eggs are produced after this point. There are around 1 million eggs at birth, with only about 300,000 remaining by puberty. Only 300 to 400 of them will be fertilised over a woman's reproductive lifetime.

Complete solution:-
The primary oocyte within the tertiary follicle develops in size and completes its first meiotic division at the tertiary follicle stage. The creation of a big haploid secondary oocyte and a little first polar body is the outcome of an unequal division. The parent oocyte's nutrient-rich cytoplasm is retained in the subsequent oocyte. The completion of the meiotic division of the secondary oocyte is induced by the sperm piercing the secondary oocyte during fertilisation. The second meiotic division is also uneven, resulting in the development of a haploid ovum and a second polar body (ootid). The haploid nuclei of the sperm and the ovum eventually combine to form a diploid zygote.

So the correct answer is C polar bodies.

The primary oocyte within the tertiary follicle develops in size and completes its first meiotic division at the tertiary follicle stage. The creation of a big haploid secondary oocyte and a little first polar body is the outcome of an unequal division.

Gametogenesis in Women (Oogenesis): By the fifth month of foetal life, all primary oocytes have developed and are quiescent in the prophase of meiosis I until puberty. One oocyte is chosen to complete meiosis I and generate a secondary oocyte (1N,2C) and a first polar body during a woman's ovarian cycle.

Note:-
These substances help your uterus contract and shed its lining each month by stimulating the smooth muscles in your uterus. When your body creates more prostaglandins than it requires, they enter the circulation and have a comparable effect on other smooth muscles in your body, such as those in your bowels.
