seminal vesicle

Either of a pair of glandular pouches that lie one on either side of the male reproductive tract posterolateral to the urinary bladder and in the human male secrete a sugar- and protein-containing fluid into the ejaculatory duct. Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the seminal vesicle is

Either of a pair of glandular pouches that lie one on either side of the male reproductive tract posterolateral to the urinary bladder and in the human male secrete a sugar- and protein-containing fluid into the ejaculatory duct. The atlas records it as a gland at the organ scale in the human body.

Where the seminal vesicle is

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

What the seminal vesicle connects to

The atlas records 11 typed relationships for it, across 7 kinds of connection. part of testis.

Supply and innervation

Arterial supply: middle vesical artery.

Questions

Where is the seminal vesicle?

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

What does the seminal vesicle connect to?

Part of: testis.

Is the seminal vesicle the same in other species?

Leumas holds the same relationship vocabulary for every species it carries, so where another dataset records this structure you can put the two side by side on /compare.
