endometrium
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 human body.
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 19 typed relationships for it, across 8 kinds of connection. part of reproductive system, uterine wall 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: reproductive system, uterine wall and uterus.
Is the endometrium 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.
