What is the role of the cloacal membrane during embryonic development?
Understand the Problem
The question is asking about the specific function of the cloacal membrane in embryonic development. The options provided indicate various roles that it could potentially play, and the asker is likely seeking clarification on which of these is correct.
Answer
The cloacal membrane forms the anus by rupturing to create urogenital and anorectal passages.
The cloacal membrane is located at the caudal end of the embryonic disc and it eventually ruptures to create passages for the urogenital and anorectal openings, forming the anus.
Answer for screen readers
The cloacal membrane is located at the caudal end of the embryonic disc and it eventually ruptures to create passages for the urogenital and anorectal openings, forming the anus.
More Information
The cloacal membrane plays a critical role during embryogenesis by ensuring the separation and proper formation of urogenital and anorectal structures.
