Structures of reproductive system are derived from which 2 germ layers?
Mesoderm
Endoderm
What are the 3 layers of the mesoderm?
Paraxial mesoderm
Intermediate mesoderm
Lateral plate mesoderm
Which ducts produce testis?
Mesonephric
Wolffian duct
Which ducts produce ovaries?
Paramesonephric
Mullerian duct
What does the mesonephric ducts form?
Epididymis Thick walled ductus deferens Seminal vesicle Ejaculatory duct Testis
What does the paramesonephric duct form? (from mesoderm layer)
Uterine tubes
Uterus
Cervix of uterus
Upper part of the vagina
How is the uterus formed?
Fusion of the 2 paramesonephric ducts (left and right) forms uterus
Paramesonephric duct is from what layer?
Mesodermal germ layer
Urogenital sinus of cloaca is part of what layer?
Endodermal germ layer
Urogenital sinus of cloaca(part of endodermal germ layer) contributes to what structures?
Urinary bladder Urethra Prostate Urethral and paraurethral glands Vaginal External genitalia
Epispadias
rare birth defect located at the opening of the urethra. In this condition, the urethra does not develop into a full tube, and the urine exits the body from an abnormal location
