primary oocyte (within primary follicle)-->first meiotic division-->secondary oocyte + 1st polar body --> second meiotic division -->fertilized oocyte + 2nd polar body
•Mitoses of spermatogonia and then transform into primary spermatocytes (largest germ cell)
•Meiosis I of primary spermatocyte forms two haploid secondary spermatocytes (transient) which undergo meiosis II to form 4 haploid spermatids still connected by cellular bridges.
•Spermiogenesis is conversion of spermatids to mature sperm (no longer interconnections)
acrosomal cap enlarges to cover the anterior half of nucleus which is condensing – it is now the acrosome
it contains hyaluronidase, neuraminidase, acid phosphatase, and trypsin-like protease the acrosomal contents will be released upon contact with the oocyte
(becomes specialized lysosome)
–nucleus becomes elongated, the axoneme is in the lumen, one of the centrioles forms the flagellum (middle piece)
2.meiotic resting stage of oogenesis is called the ____
1.primary oocytes are arrested in the diplotenestage of Prophase I
Follicular cells divide to become the single layer of cuboidal cells (primary follicles) which are _____ Further division will form _____ ____ ____ (secondary follicles) cells connected by gap junctions.
Follicular cells secrete fluid into the space between follicular cells creating an antrum as the spaces coalesce it now is called a ___ ____
•Follicular cells secrete ___ ___ ___ (OMI) to keep oocyte in dictyotenephase
