Click on the flashcard to see the answer

What is oogenesis?

Oogenesis is the process of egg cell formation in females.

Where does oogenesis occur in the body?

Oogenesis occurs in the ovaries.

What is the starting cell in oogenesis?

Oogenesis starts with oogonia.

What are primary oocytes?

Primary oocytes are cells that undergo the first meiotic division during oogenesis.

What triggers the completion of the first meiotic division in oogenesis?

The LH surge triggers it during ovulation.

What is formed after the first meiotic division of a primary oocyte?

A secondary oocyte and a polar body are formed.

At what stage is a female's egg cell released during ovulation?

The secondary oocyte is released during ovulation.

What happens to the secondary oocyte if fertilization occurs?

It completes the second meiotic division to form a mature ovum.

What is a polar body, and why is it produced?

A polar body is a small cell produced to discard extra genetic material.

How many mature egg cells are typically produced from one primary oocyte?

One mature egg cell is produced.

What role do granulosa cells play in oogenesis?

Granulosa cells support and nourish the developing oocytes.

How does oogenesis differ from spermatogenesis?

Oogenesis produces one egg, while spermatogenesis produces four sperm per precursor cell.

What is the biological significance of oogenesis?

Oogenesis ensures genetic variation and the formation of viable egg cells for reproduction.

What is menopause's impact on oogenesis?

Menopause marks the end of oogenesis as ovarian follicle depletion occurs.

Why is only one dominant follicle typically ovulated?

To ensure adequate resources and support for the developing oocyte.
