Female Reproductive System

Question 1

Gamete and Gonad of female reproductive system?

Answer 1

gamete = ovum, oocyte, egg
gonad = ovaries

Question 2

What are the ligaments that are supporting structures of the female reproductive system?

Answer 2

1. Ovarian Ligament
   - anchors ovary to uterus
   - no vascular structures
2. Suspenary Ligament
   - anchor ovary to lateral wall of pelvis
   - NAVL
   - Ovarian Artery & Vein
   - Lt ovarian v. drain into Lt renal vein
3. Broad Ligament
   - peritoneal fold over the Uterus
   - NAVL pathway
4. Mesovarian
   - suspends ovaries from uterine tube
   - NAVL pathway

Question 3

What is the round ligament and where does it pass?

Answer 3

• A ligament similar to the spermatic cord.
• Attach from uterus to Labia Majora & passes through the inguinal canal
• why pregnant women have groin pain because pulls on round ligament

Question 4

Describe all the ovarian follicles

Answer 4

1. Primordial Follicle
   - born w/ all primordial follicles your going to have
   - Primary Oocyte
   - Follicular cells
   (simple squamous cells)

–> Increase FSH
(small amt LH too)

2. Primary Follicle
   - triggered by FSH
   - Primary Oocyte
   - Granulosa Cells
   (cubiodal cells w/ glandular function)
   –> Estrogen
   –> Progesterone
   (after ovulation)
3. Secondary Follicle
   - Primary Oocyte
   - Granulosa cells produce more estrogen
   - produce follicular fluid pockets
4. Graafian (Mature) Cell
   - Secondary Oocyte
   - Antrum of follicular fluid
   - Estrogen reach HIGHEST level

Question 5

What happens on day 14 ?

Answer 5

Mature follicle ruptures & eject secondary Oocyte

-> corpus hemorrhagic
-> corpus luteum
- LH increase, progesterone high & estrogen low

-> corpus albican
- progesterone makes a neg feeback on LH qhich causes death or corpus luteum leaving a scar
