Oogenesis
The production of ova
What is oogenesis?
Haploid Nucleus
What kind of nucleus exists in egg cells?
The structure consisting of the primary oocyte surrounded by follicle cells
What is the primary follicle?
Mitosis-->Cell Growth --> Two Meiotic Divisions --> Cell Differentiation
What is the gametogenesis process undergone by both spermatogenesis and oogenesis?
The ovaries
Where does oogenesis occur?
One gamete (plus polar bodies)
What is the product of Oogenesis?
110 micrometers
What is the diameter of an egg?
What is Prophase I?
Haploid Nuclei
What is a similarity between spermatogenesis and oogenesis?
When does oogenesis start?
Ovary cortex
Where do the diploid cells distribute after oogonia do mitosis?
Layer of follicle cells
What is the corona radiata?
The cell that is released from a mature follicle at ovulation
What is a secondary oocyte?
Organelle that sperm has a small quantity of, and the egg has a large quantity of
What is the cytoplasm?
When does oogenesis end/when is the ovum development complete?
Cellular arrests
What are the "pauses" on cell division called?
Organelle that hardens the zona pellucida to inhibit multiple fertilization
What are cortical granules?
Cell type from fetal stage until puberty
Hint: The process to create this cell is mitosis and cell growth
What is a Primary Oocyte?
Asymmetric
What is the type of cell division the oogonium undergoes?
400,000
How many primary follicles are present at birth?
Degeneration
What is done by polar cells?
Zona Pellucida
What is the name of the gel membrane made up of glycoproteins that prevents polyspermy?
The meiotic stage of the secondary oocyte chosen for release/fertilization
What is Metaphase II?
Difference in the production of egg cells that causes the egg to be bigger than the sperm
What is the release of Polar Bodies?
3 follicle cell layers, secondary oocyte in prophase I, and follicular fluid
What is the mature follicle made up of?
