Follicle ruptures at ovulation, releasing the ovum Corpus Hemoragicum and then corpus Luteum form at the ovulation site. Ovaries Cytogenic function The ovary is encapsulated in a dense connective tissue capsule, the tunica albuginea The cortex (outer portion) of the ovary consists of dense, irregular connective tissue interspersed with: Follicles (contain developing ova) in various stages of development - Corpora hemorrhagicum-blood filled Corpora luteum yellow body Corpora albicans white body Ovaries Primary Follicles Graafian follicle - large dominant follicle (smaller ones regress) Oocyte surrounded by single layer of cuboidal epithelium or follicular cells Ovulation involves thinning of tissue layer and changes in follicular fluid pressure Ovarian Follicles Ovaries...
