Ovary
-- site of oocyte formation and maturation within follicles
Examine each of sections of ovary at low power and observe the number of variety of
follicles present. Most follicles are located in the
cortex surrounding the medulla. With higher power, identify the
capsule with the simple cuboidal surface epithelium and dense
irregular supporting tissue stroma. Part of oviduct and well-vascularized
mesentery supporting the ovary are also present here. Click image at

How does the germinal
epithelium differ from most mesothelia in the body?
When do primordial follicles develop?
What is the major function of granulosa cells and the significance
of the zona pellucida?
What types of cells are present in the theca interna?
How exactly does the antrum relate to the process of ovulation?
What is the difference between the cumulus Oophorus and the corona
radiata and what exactly is released from the ovary at ovulation?
Clinical note: Surprisingly,
perhaps, ovarian cancer most commonly involves cells of the surface
epithelium. When the disrupted epithelium heals after ovulation,
epithelial cells can be displaced into the stroma and give rise
there to cysts which have the potential to become neoplastic.
