mesonephric duct in dogs

Paired organ that connects the primitive kidney Wolffian body (or mesonephros) to the cloaca and serves as the anlage for certain male reproductive organs. the Wolffian duct is what remains of the pronephric duct after the atrophy of the pronephros[WP]. In Zebrafish: Duct of the adult kidney (mesonephros), present bilaterally ventral to the somites and leading to the cloacal chamber[ZFA].

What the mesonephric duct is

Paired organ that connects the primitive kidney Wolffian body (or mesonephros) to the cloaca and serves as the anlage for certain male reproductive organs. the Wolffian duct is what remains of the pronephric duct after the atrophy of the pronephros[WP]. In Zebrafish: Duct of the adult kidney (mesonephros), present bilaterally ventral to the somites and leading to the cloacal chamber[ZFA]. The atlas records it as a tissue at the tissue scale in the dog.

Where the mesonephric duct is

It sits in the abdomen and trunk, within the urinary system. Only the region is known. The position shown is somewhere plausible inside it and nothing more.

What the mesonephric duct connects to

The atlas records 12 typed relationships for it, across 5 kinds of connection. part of kidney, mesonephros and organ, and 1 more.

Supply and innervation

This dataset asserts no arterial supply, venous drainage or innervation for the mesonephric duct. Only a minority of structures carry those edges here, so an empty answer means nothing has been recorded — not that there is nothing to record.

Also called

Also recorded as Wolffian duct, Leydig's duct, archinephric duct, ductus mesonephricus; ductus Wolffi and renal duct. Searching any of those names reaches this page.
