Development of femalegenital system (2)

Question 1

Upper and middle part of paramesonephroc duct will form

Answer 1

Uterine tubes
Upper will form fimbrae

Question 2

The lower paramesonephric duct/uterovaginal canal will form

Answer 2

4/5 of vagina

Question 3

How is the lower 1/5 of vagina formed ?

Answer 3

It is formed from mullerin tubercle, the mullerin tubercle will form 2 sino vaginal bulb that will unite together and form vaginal plate. The vaginal plate canalize to form lower 1/5 of vagina

Question 4

How is the hymen formed ?

Answer 4

Is formed by junction of the definitive urogenital sinus and lower 1/5 of vagina

Question 5

Answer 5

Vaginal plate

Question 6

Question 8

Parts of external genitalia and what do they give rise to

Urethral/urogenital folds form labia minora
Labiaswelling gives rise to labia majora and the urethral groove forms the vestibule

Question 9

Anamloies of uterus

Answer 9

Unicate ( failure of one parameaonephric duct from forming)

Bicunate( heart shaped and failure of fusion of upper uterovaginal canal and septum persists)

Double uterus (failure of fusion of lower paraneaonephric duct)

Sepetate (septum persists) arcuate (normal but small indentation)

Question 10

Cervical and vaginal anamolies

Answer 10

Cervical atresia (incomplete development of upper and lower vagina)

Vaginal Atresia , double vagina, transversely septate vagina( faulty canalinization of mullerin ducts)
Imperforate hymen
