wolffian body การใช้

The paradidymis represents a remnant of an unused, atrophied part of the Wolffian body.
These tubes are lined with columnar ciliated epithelium, and probably represent the remains of a part of the Wolffian body, like the epididymis, but are functionless and vestigial.
The Wolffian body operates as a kidney ( mesonephros ) in fishes and amphibians, but the corresponding tissue is co-opted to form parts of the male reproductive system in other classes of vertebrate.
In the female, on the other hand, the Wolffian bodies and ducts atrophy, leaving behind only remnants in the adult, involving e . g . the development of the suspensory ligament of the ovary.
