The term "Wolffian body" refers to a structure found in the embryonic development of animals. This body, also known as mesonephric duct or ductus deferens, plays a crucial role in the development of the male reproductive system. While "Wolffian body" is the commonly used term, there are a few synonyms that can be used interchangeably. These include mesonephric tubules, mesonephros, or even Mullerian duct, depending on the specific context. Regardless of the synonym used, it is important to understand that these terms refer to the same anatomical structure involved in the formation of the male reproductive system in embryonic animals.
