The reproductive system ensures the survival of the species. Other systems in the body, such as the endocrine and urinary systems, work continuously to maintain homeostasis for the survival of the individual. An individual may live a long, healthy, and happy life without producing offspring, but if the species is to continue, at least some individuals must produce offspring.

The Graafian follicle is the follicular stage that occurs after the first meiotic division but prior to ovulation. As a result, it contains a 2N haploid oocyte. It is distinguished by a large follicular antrum that occupies the majority of the follicle. The secondary oocyte is located eccentrically after the first meiotic division. It is…[Read more]

The presence of a follicular antrum within the granulosa layer distinguishes secondary follicles from primary follicles. This space is filled with a fluid called liquor folliculi. The oocyte and the zona pellucida are also visible in this image. The theca interna, which produces hormones, surrounds the follicle.

When follicular cells proliferate into a stratified epithelium known as the zona granulosa, the follicle reaches the late primary follicle stage. This image shows the zona pellucida even more clearly.

The primary follicle has a central oocyte and is surrounded by a single layer of cuboidal cells. The zona pellucida is a thin band that separates these two layers.

Before releasing its ovum, an ovarian follicle goes through several stages. A limited number of primordial follicles form in the fetal ovary during the first five months of development. Oocytes are surrounded by a single layer of squamous follicular cells in these follicles. These primordial follicles are still undergoing the first meiotic…[Read more]

Microscopic Photos of Reproductive System Tissue Slides 3 years, 7 months agoSeminal vesicles are glands that produce the fluids that turns into semen. The seminal vesicles appear as honeycombed saccules with thin, highly branched folds of mucosa, lined by a pseudostratified columnar epithelium. These folds join one another to delimit irregular spaces, which communicate with a large, central lumen filled with a… -

The Fallopian tube's inner mucosal layer is responsible for delivering gametes and embryos, as well as tubal fluid discharges. Epithelial cells and the lamina propria mucosa, a network of connective tissue with a mixed cell population, make up the endosalpinx. Ciliated epithelial cells and nonciliated secretory epithelial cells make up the…[Read more]

The corpus luteum is the endocrine remnants of the follicle that has collapsed. The blood clot that formed after ovulation is still present in the center. Glanulosa lutein cells surround the clot, and theca lutein cells surround it on the outside.
