| 1. | The female urogenital sinus also gives rise to the urethra and vestibule of the vagina.
|
| 2. | The anterior portion becomes the urogenital sinus.
|
| 3. | The prostate forms from the urogenital sinus and the efferent ducts form from the mesonephric tubules.
|
| 4. | The female reproductive system is composed of two embryological segments : the urogenital sinus and the paramesonephric ducts.
|
| 5. | Females have an external clitoris and a urogenital sinus, which acts as both a urethra and vagina.
|
| 6. | Embryologically, the bladder is derived from the urogenital sinus, and it is initially continuous with the allantois.
|
| 7. | The urethra typically opens into a common channel with the vagina ( i . e . urogenital sinus ).
|
| 8. | The remainder of this part of the urogenital sinus forms the body of the bladder and part of the prostatic urethra.
|
| 9. | After the separation of the rectum from the dorsal part of the cloaca, the ventral part becomes the primary urogenital sinus.
|
| 10. | The urogenital sinus, in turn, divides into the superficial definitive urogenital sinus and the deeper anterior vesico-urethral portion.
