endometrium in dogs

The glandular mucous membrane lining of the uterine cavity that is hormonally responsive during the estrous/menstrual cycle and during pregnancy. Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the endometrium is

The glandular mucous membrane lining of the uterine cavity that is hormonally responsive during the estrous/menstrual cycle and during pregnancy. The atlas records it as a tissue at the tissue scale in the dog.

Where the endometrium is

It sits within the reproductive system. Not positioned individually. Drawn inside the structure this dataset says contains it — the containment is asserted, the exact spot within it is not.

What the endometrium connects to

The atlas records 12 typed relationships for it, across 6 kinds of connection. part of organ, reproductive system and uterus.

Supply and innervation

Arterial supply: uterine spiral artery.

Also called

Also recorded as tunica mucosa (endometrium), tunica mucosa uteri, uterine endometrium, uterine mucosa and uterine mucous membrane. Searching any of those names reaches this page.

Questions

Where is the endometrium?

It sits within the reproductive system. Not positioned individually. Drawn inside the structure this dataset says contains it — the containment is asserted, the exact spot within it is not.

What does the endometrium connect to?

Part of: organ, reproductive system and uterus.

Is the endometrium 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.
