Anatomy, Histology and Embryology of the Female Reproductive Tract Flashcards
What type of epithelium lines to extocervix?
Non-keratinising stratified squamous epithelium
What type of epithelium lines to endocervix?
Columnar epithelium
In which area do cervical neoplasias usually develop?
The transformational zone
The squamous epithelium of the extocervix becomes everted into the vagina due to growth fo the cervix in puberty and so adapts to the vaginal environment. What is the name of this adaptive process?
Squamous metaplasia
What type of epithelium is present in the Fallopian tube?
Ciliated columnar epithelium
What is the default setting for reproductive development?
Female
What gene is the main determinant of male reproductive development?
SRY
From what structure in the embryo do the gonads arise?
Urogenital ridge
Why do the wolffish ducts regress in females?
Lack of testosterone
Why do the mullerian ducts persist in females?
Lack of anti-mullerian hormone which is produced by Sertoli cells in males
What structures do the mullerian ducts form?
Oviduct, uterus, Fallopian tubes and upper third of vagina
What structure does the wollfian duct form in females?
Trigone of the bladder
The female bladder, other than the trigone, is formed from which embryological structure?
Urogenital sinus
What structures does the urogenital sinus form in females?
Bladder, other than trigone
Bulbourethral gland
Urethra
Lower two thirds of vagina
In both sexes the external genitalia are indistinguishable until which week of gestation?
12 weeks
