Embryology Qus Flashcards
What does the mesonephric duct become in males and females
Ductus deferens and the epididymis
In females this dissapears
In males, what does the Paramesonephric duct (Mullerian duct) become
Degenerates
In females, what does the Paramesonephric duct (Mullerian duct) become
Fallopian tube, uterus, cervix and part of the vagina
What does the indifferent gonad differentiate into in the male and female
Male: testes
Female: ovaries
In males, what does the urogenital sinus develop to form?
Bladder, urethra and prostate
In females what does the urogenital sinus develop to form?
Bladder and lower part of the vagina
How does the indifferent gonad know to form the testes?
> SRY gene codes for a protein known as TDF (testes determining factor)
SRY gene is found on the Y chromosome
In females, what does the absense of testosterone cause
> degeneration of the mesonephros and mesonephric duct
Paramesonephric duct develop to give rise to the female genital tract
What does the descent of the gonads result in for males
Larger inguinal canal, testes descended
What does the descent of the gonads result in for females
Presense of the round ligament and its passage through the ingunal canal
What is Cryptorchidism
Absense of at least one teste from the scrotum
1. Undescended
2. Ectopic
3. Retractile testes
4. Absent testes
What are gardner cysts?
Cysts near the ovary/vagina, which can impact feritlity. These are results of remnants of the mesonephric ducts.
What is this
Complete duplication of paramesonephric duct
What is this
Bicornuate uterus
(Uterus appears heart shaped)
What is this
Septate uterus
What is this
Arcurate uterus
(uterus has a small dent at the top: doesnt impact health/fertility)
