Lecture 37 Female reproductive system II Flashcards
Female reproductive tract
Ovary (oocyte) Infundibulum (fimbriae) Ampulla (fertilization) Isthmus Uterus body Uterus fundus Cervix Fornix Vagina Vulva
When oocyte is ovulated what does it go into?
Infundibulum - fimbriae
What is the first part of the uterine tube?
Infundibulum
Where does fertilisation occur?
Ampulla
Whats the region moving into the uterus?
Isthmus
Whats the layer in the middle of the uterus?
Endometrium
What occurs in the endometrium?
Implantation
Where foetus will grow and develop
Whats the little gap that forms an arch between the wall of the uterus and vagina is known as the?
Fornix
What is the external genitalia known as?
Vulva
where does oogenesis occur?
within ovary
whats oogonia?
Stem cells of females
Spermatogenesis
Begins during puberty
Sperm produced on a daily basis
In a female the lifetime supply of oocytes are produced when?
Before birth
Process of oogenesis
Occurs before birth
Continues between puberty and menopause
whats oogenesis?
Formation and development of the oocyte (female gamete) from oogonia.
in oogenesis oocytes develop where?
within ovarian follicles (1 oocyte per follicle).
Oogenesis is cyclic
1 ovulation every 28 days (on average)
Oogenesis requires
mitosis and meiosis
In Oogenesis the Oogonia undergoes mitosis and produce
2 daughter cells (1 which produces itself and 1 that differentiates to form the primary oocyte)
Diploid 2n=46
In Oogenesis the Primary oocyte undergoes meiosis and produce
2 cells (1 produce 1st polar body, 1 produce secondary oocyte)
In Oogenesis the Secondary oocyte undergoes meiosis 2 and produce
Only complete meiotic division if penetration by the sperm
Produce 2 cells (polar body, fertilized oocyte - zygote)
