urethra in dogs

The fibromuscular tubular canal through which urine is discharged from the bladder to the exterior via the external urinary meatus; in males, the urethra is joined by the ejaculatory ducts and serves as a passageway for semen during ejaculation, as well as a canal for urine during voiding; in females, the urethra is shorter and emerges above the vaginal opening. Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the urethra is

The fibromuscular tubular canal through which urine is discharged from the bladder to the exterior via the external urinary meatus; in males, the urethra is joined by the ejaculatory ducts and serves as a passageway for semen during ejaculation, as well as a canal for urine during voiding; in females, the urethra is shorter and emerges above the vaginal opening. The atlas records it as a organ at the organ scale in the dog.

Where the urethra is

It sits within the urinary system. Positioned deliberately as part of this species body plan.

What the urethra connects to

The atlas records 26 typed relationships for it, across 8 kinds of connection. part of lower urinary tract.

Supply and innervation

This dataset asserts no arterial supply, venous drainage or innervation for the urethra. 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.
