Historical Examples of mesonephric
The mesonephric ducts (w.d), the other product of the segmental ducts of the kidneys.
The mesonephric duct receives the secretion of the anterior tubuli of the primitive mesonephros.
The mesonephric tubules, called also the Wolffian body, open into this duct.
From this original nephrocœle are formed the pronephric excretory organs, the mesonephric excretory organs, and the body-cavity.
They differ also from the mesonephric tubules by not being so clearly segmental with the myotomes.
