epididymis in dogs
The elongated structure connected to the posterior surface of the testis that transports, stores, and matures spermatozoa between testis and vas deferens. Every claim on this page comes from the Leumas anatomy graph and carries its source.
What the epididymis is
The elongated structure connected to the posterior surface of the testis that transports, stores, and matures spermatozoa between testis and vas deferens. The atlas records it as a organ at the organ scale in the dog.
Where the epididymis is
It sits within the reproductive system. Only the system is known. The position shown carries almost no spatial information.
What the epididymis connects to
The atlas records 19 typed relationships for it, across 7 kinds of connection. part of anatomical entity, internal male genitalia and male reproductive system, and 2 more.
Supply and innervation
This dataset asserts no arterial supply, venous drainage or innervation for the epididymis. 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.

Questions
Where is the epididymis?
It sits within the reproductive system. Only the system is known. The position shown carries almost no spatial information.
What does the epididymis connect to?
Part of: anatomical entity, internal male genitalia, male reproductive system, organ and reproductive system.
Is the epididymis the same in other species?
This page describes the dog. The human record of the same structure sits beside it on /compare, over one shared model rather than two atlases built separately.
