Cloaca (embryology) - Wikipedia
The cloaca is, for a time, shut off from the anterior by the cloacal membrane, formed by the apposition of the ectoderm and endoderm, and reaching, at first, as far forward as the future umbilicus. Behind the umbilicus, however, the mesoderm subsequently extends to form the lower part of the abdominal wall and pubic symphysis .
The development of the cloaca in the human embryo - PMC
This study aimed to clarify the development of the cloaca using a quantitative 3D morphological approach in human embryos of 4–10 post‐fertilisation weeks. Embryos were visualised with Amira 3D‐reconstruction and Cinema 4D‐remodelling software.

After the embryonic period, the "embryo" is defined by the crown-rump length. Using the Carnegie Collection as well as their own materials, deVries and Friedland 4 characterized the development of the cloaca, cloacal membrane, urogenital sinus, and anorectum as taking place between weeks 3 and 8, respectively.

Cloaca - an overview | ScienceDirect Topics
A cloaca is a common chamber into which some or all of the digestive, urinary, and reproductive tracts discharge their contents. A cloaca exists in all human embryos up to 4–6 weeks, at which time it becomes partitioned into the urogenital sinus and the rectum. A cloaca forms when the cloacal membrane does not recede or the mesoderm does not ...
