Study Notes
Ovary
- Produces ova and female sex hormones
- Composed of outer cortex and inner medulla
- Medulla formed of fibroelastic connective tissue with abundant blood vessels and smooth muscle fibers
- Cortex covered by germinal epithelium, consists of ovarian follicles in various stages of development in a dense stroma
Ovarian Follicles
- Consist of primordial, primary, secondary, and mature follicles
- Primordial follicle: primary oocyte surrounded by a single layer of flat follicular cells
- Primary follicle: follicular cells transform into cuboidal then stratified epithelium (granulosa cells), ovum surrounded by zona pellucida
- Secondary follicle: intercellular spaces develop in granulosa cells, filled with liquor folliculi, and stromal cells condense to form theca cells
- Mature Graafian follicle: cavities unite to form follicular antrum, occupies the whole thickness of the cortex, ovum anchored by cumulus oophorus
Ovulation and Corpus Luteum
- Ovulation: hormone-stimulated process by which the oocyte is released from the ovary, occurs midway through the menstrual cycle
- After ovulation, the mature Graafian follicle changes into corpus luteum
Uterus
- Wall composed of endometrium, myometrium, and perimetrium
- Endometrium: composed of epithelium and lamina propria
- Epithelium: simple columnar epithelium, partially ciliated and partially secretory
- Lamina propria: dense collagenous connective tissue containing several cells and fibers, contains endometrial glands
