| Term | Definition |
| What are the female gonads called? | Ovaries |
| What is Oogenesis? Describe in 1-2 sentences. | Oogenesis is the process to create ovum |
| When does Oogenesis start during the lifespan of a female human? How do Oognonia give rise to Primary Oocytes? | Oogenesis starts before female is even born. Oognonia does mass mitosis to create millions of primary oocytes |
| After birth, when does meiosis resume? When does meiosis officially finish? | Meiosis resumes at puberty and meiosis II resumes immediately after sperm penetrates it. |
| How many ova are made during Oogenesis? How is a mature ovum physically different than a spermatid (product of spermatogenesis before spermiogenesis)? What are polar bodies? | One ovum is made during oogenesis - different than spermatogenesis instead of creating four haploid cells oogenesis creates one large ovum and lots of polar bodies. |
| What is ovulation? Typically, how long is an ovarian cycle? When does the ovarian cycle start occurring in the lifespan of a female human? | Ovulation is the release of a secondary oocyte into the female reproductive system. The ovarian cycle is 28 days and it starts occurring at puberty |
| What type of ovarian follicles are primary oocytes held in before puberty? | Primordial Follicles hold primary oocytes before puberty |
| Describe the stages of follicular development . What are the physical changes in the follicles if it morphs into new follicular stages? How long does it take for a primordial follicle to become a tertiary follicle? | 1. Primordial Follicle 2. Primary Follicle 3. Secondary Follicle a. Takes two months 4. Tertiary Follicle a. First seven days of follicular phase (first seven) only one follicular follicle is left |
| What is Atresia? | Atresia cells are picked to collapse and decay |
| What hormones stimulate the growth and development of follicles? Where does this hormone come from? | Estrogen. The hypothalamus secretes GnRH and then the pituitary gland secretes luteinizing hormone and follicle-stimulating hormone |
| How many tertiary follicles will ovulate each ovarian cycle? | One |
| What does the leftover follicular tissue after ovulation change into? What is its primary function for the rest of the ovarian cycle? | Changes into corpus luteum and secretes hormones |
| What determines when a corpus luteum becomes a corpus albicans? | After 10-14 days corpus luteum becomes a corpus albicans. Signals end of the ovarian cycle. |
| What is the function of the uterus? What are the three openings to the uterus? What passes through each of those openings? | Womb, the baby develops, the fetus grows. Three openings of the uterus - Isthmus of the uterine tube o Lead egg to uterus - Cervix o Period, Sperm Baby |
| What structure connects the ovaries to the uterus? What are the fimbriae of the uterine tube, and what do they do? | Fimbriae connects the ovary to the uterus. - Physically collect egg and lead into the fallopian tube |
| What is the primary function of the two inner layers of the uterus? | Endometrium - Egg anchors itself to endometrium Myometrium - Smooth Muscle - Contract to push baby out of the vagina |
| Describe the phases of the menstrual cycle. | Menstrual Phase: Endometrium comes off the uterus Proliferative Phase: Build up endometrial Secretory Phase: Develop endometrial glands / blood vessels |
| What hormone (or lack of hormone) triggers menses? What hormone stimulates the proliferative phase? What hormone stimulates the secretory phase? | Menstrual Phase: DROP in progesterone Proliferative Phase: RISING of Estrogen Secretory Phase: RISING of progesterone |
| How many external orifices does the female reproductive system have, and what are they? What structures cover these orifices? | 2 orifices. Urethral Orifice and Vaginal Orifice. - Labia minor and Labia Major cover |
| What is the function of vestibular glands? | - Secrete lubrication |
| Connect? o Alveoli o Lactiferous ducts o Lobes o Suspensory ligaments o Lactiferous sinus o Nipple | Lobe is made up of glandular alveoli. Connecting lobes are is suspensory ligament. Laciferous ducts collect milk from lobe to nipple. Lactiferous sinuses can store milk temporarily. |
