mammillary body

One of two hemispherical bulges on the base of the posterior hypothalamus (Butler and Hodos, Comparative Vertebrate Neuroanatomy, 2nd ed., 2005, pg 455). Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the mammillary body is

One of two hemispherical bulges on the base of the posterior hypothalamus (Butler and Hodos, Comparative Vertebrate Neuroanatomy, 2nd ed., 2005, pg 455). The atlas records it as a organ at the organ scale in the human body.

Where the mammillary body is

It sits within the nervous 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 mammillary body connects to

The atlas records 12 typed relationships for it, across 4 kinds of connection. part of limbic system, medial zone of hypothalamus and posterior hypothalamic region.

Supply and innervation

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

Also called

Also recorded as MMB, corpus mamillare, corpora mamillaria, corpora mammillaria, corpus mamillaris and corpus mammillare, and 1 more. Searching any of those names reaches this page.

Questions

Where is the mammillary body?

It sits within the nervous 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 mammillary body connect to?

Part of: limbic system, medial zone of hypothalamus and posterior hypothalamic region.

Is the mammillary body 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.
