When a primary oocyte divides a secondary oocyte and what are produced?
polar body
What forms part of the primary follicle in the ovary?
A primary follicle consists of a primary oocyte surrounded by a single layer of enlarged cuboidal epithelium. Recall that previously, there was a primary oocyte in a primordial follicle surrounded by a thinner single layer of squamous follicular cells.
When the primary oocyte divides a secondary oocyte and what else is produced?
first polar body
What surrounds a primary oocyte?
follicle cells
What does follicle stimulating hormone promote the development of?
primary follicle/oocyte
During oogenesis an oogonium directly gives rise to what?
A primary oocyte
A primary oocyte is closely surrounded by flattened epithelial cells called?
follicular
Prenatal maturation of oocyte?
Primordial, secondary, tertiary, and antral are the basic steps in a developing oocyte
How many eggs are produced from one oocyte?
one cell is produced from one primary oocyte.
Difference between primary and secondary oocyte?
Any oogonia that has arrested itself in meiosis I prophase-dipotene on the onset of OMI (oocye maturation inhibition) hormone in the 3rd month of pregnancy and there after is a primary oocyte. On the urge of Leutinizing hormone which induces the pre-ovulatory phase, the primary oocyte completes meiosis I and arrests itself in meiosis II metaphase, which would only be completed if fertilization occurs, otherwise it will degenrate in 24 hours. On the completion of meiosis I, a SECONDARY oocyte and forst polar body is going to be formed.
How many egg cells come form a female germ cell?
One primary oocyte divides by meiosis and produces one polar body and one secondary oocyte. The polar body goes on to produce two more polar bodies, and the secondary oocyte divides into one polar body and one ovum. Therefore, one cell is produced from one primary oocyte.
Where is the oocyte found?
cryptosporidium spp, has oocyte which is passed in feces.
