Female Reproductive System Flashcards
What are the primary sex organs and what is there function
Ovaries
Responsible for gamete production
Name accessory sex organs
Vagina
Uterus
Clitoris
What are the secondary sex characteristics and how/when do they occur
Breast and mammary gland development
Wide pelvic structure
Bone density
Fat deposition pattern
During puberty- mediated by estrogen
Uterus layers
Myometrium- muscle layer- contractile
Endometrium- tissue build up and shed
What is it called when the egg implants in uterine tube
Ectopic pregnancy
Role of cilia and peg cells on fimbrae
Cilia- beat to pull ovum near uterine duct
Peg- secrete nutrients for ovum and sperm
Which external skin have hair and don’t have hair
Hair- labium majora, mons pubis
No hair- labium minora
When are primary follicles made
Within 5 months of gestation
What is syngamy
Union of egg and sperm
Where does the embryo implant
Endometrium
Functions of female sex organs
- oogenesis
-facilitating syngamy - provide site for implantation of embryo
- provide physical environment and nutritional needs for developing fetus
- provide pathway for parturition and nourish the neonate
Number oocytes locked in prophase 1
7 million
Number oocytes at puberty
300 000
Number eggs full maturation
450
What are polar bodies
Byproduct that do not become fertilized
Steps of oogenesis
- primordial follicles appear in mid-gestation and divide (mitosis) until 5th month
- 7 million potential primary oocytes enter meiosis 1 and are locked in prophase 1
- reduce to 300 000 by puberty (level of reproductive maturity) that undergo further development
- most oogonium never progress to full maturity- estimated 450 eggs mature and release during ovulation
- oocytes locked in M1 until ovulation, M2 completed after fertilization
What is oogenesis
Develop ovum through maturation to level needed for fertilization
How many primary follicles will start to mature
6-12 follicles
