Seminiferous Tubules::: contains several important structures. Spermatozoa is produced in the germinal epithelium of the seminiferous tubules and released into the lumina of these ducts. The germinal lining contains both Sertoli cells and the developing spermatocytes. The interstitial space contains clumps of darker, eosinophilic cells. These are the Leydig cells, which produce and release testosterone. Myoid cells surround the tubules and generate rhythmic contractions to propel spermatozoa and fluid. They also synthesize collagen and other fibers of connective tissue.

pale in color and it has processes

larger cell primary spermatocytes more prominent than secondary because secondary spermatocytes have one of the shortest time spans for change

Follicular atresia is the breakdown of the ovarian follicles, and it is necessary in order for women to maintain a healthy reproductive system.

The Uterus
Normal cervix is seen at high power, with non-keratinizing squamous epithelium. The basal cells are seen at the right,
and there is progressive maturation to the surface, where the flattened squamous cells have a low nuclear/cytoplasmic
ratio with abundant pale-staining cytoplasm containing glycogen. The epithelium lies above the basement
membrane. The submucosa is at the far right
