  • This duct is known as the pronephric duct, mesonephric duct or Wolffian duct.
  • The development of the pronephric duct proceeds in a cranial-to-caudal direction.
  • It then passes through thin ciliated tubules into the pronephric nephron where it is processed for solute recovery.
  • Thus, the Wolffian duct is what remains of the pronephric duct after the atrophy of the pronephros.
  • Nephrotomes are not related to nephrostomes, which are thin ciliated funnels that link pronephric nephrons to the coelom.
  • As it elongates caudally, the pronephric duct induces nearby intermediate mesoderm in the thoracolumbar area to become epithelial tubules called mesonephric tubules.
  • I personally am looking forward to the day when a reader can view a wikidata-based " tree ", clicking mesoderm and seeing all of the derived structures, then selecting the intermediate mesoderm, then Pronephric duct, mesonephric duct and vas deferens.
  • In the outer part of the intermediate mesoderm, immediately under the ectoderm, in the region from the fifth cervical segment to the third thoracic segment, a series of short evaginations from each segment grows dorsally and extends caudally, fusing successively from before backward to form the pronephric duct.
