Study Notes
Mammary Glands
- Produce milk for nourishing the young in the female reproductive system
Cervix and Vagina
- The squamous epithelium is a layer of the cervix and vagina
Placenta
- Chorion and allantois are responsible for nutrient and gas exchange in the placenta
Female Reproductive System
- Produces ova, supports fertilization, and nurtures a developing fetus during pregnancy
Ovary Structure
- The stroma is the main structural component of the ovary responsible for ova production
- The medulla contains the medullary blood vessels
Estrogen Production
- The granulosa cells are responsible for producing estrogen in the ovary
Corpus Luteum
- Produces progesterone to prepare the uterus for implantation of a fertilized ovum
Graafian Follicle
- The membrana granulosa surrounds the developing ovum within a Graafian follicle
- The zona pellucida is the main structure in the ovary that blocks polyspermy and facilitates fertilization
Progesterone Production
- The corpus luteum is responsible for producing progesterone in the ovary
Androgen Production
- The theca interna cells are responsible for the production of androgens in the ovary under LH stimulation
Relaxin
- Relaxin helps relax the pelvic ligaments and widens the birth canal during childbirth
Follicle Development
- The tertiary follicle is the largest and extends from the cortex to the surface of the ovary
Granulosa Cells
- Granulosa cells proliferate and produce estrogen under the influence of FSH stimulation
Oogenesis
- A maturation arrest occurs during diplotene of meiotic prophase I in oogenesis
Cumulus Oophorus
- The granulosa cells are known for forming a mound around the oocyte called cumulus oophorus
Estrogen Role
- Estrogen stimulates the growth and differentiation of the female reproductive tract in the ovary
Learn about the anatomy of the ovary including different types of follicles. Understand the hormonal orchestration involved in the female reproductive system. Explore the structure of the uterine tube and uterus, including their layers and variations along their length.
