What does follicle stimulating hormone promote the development of?
primary follicle/oocyte
Which hormone assumes a role in the development and discharge of a secondary oocyte?
LH
Which hormone causes the thinning of cervical mucus?
the thinning of the cervical mucus is due to the estrogen spike prior to ovulation. This is caused by the primary oocyte signaling the anterior pituitary gland that it has matured and is ready for release.
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.
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
