medial geniculate body

Nuclear complex of the thalamus situated on the caudal, subpial aspect of the thalamus (Brodal, Neurological Anatomy, 3rd ed., 1981, pg 622). Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the medial geniculate body is

Nuclear complex of the thalamus situated on the caudal, subpial aspect of the thalamus (Brodal, Neurological Anatomy, 3rd ed., 1981, pg 622). The atlas records it as a nerve at the organ scale in the human body.

Where the medial geniculate body is

It sits within the nervous and sensory systems. 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 medial geniculate body connects to

The atlas records 9 typed relationships for it, across 4 kinds of connection. part of metathalamus and vestibulo-auditory system.

Supply and innervation

This dataset asserts no arterial supply, venous drainage or innervation for the medial geniculate 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 MGN, corpus geniculatum mediale, medial geniculate complex, medial geniculate nuclei, medial geniculate nucleus and nuclei corporis geniculati medialis, and 6 more. Searching any of those names reaches this page.

Questions

Where is the medial geniculate body?

It sits within the nervous and sensory systems. 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 medial geniculate body connect to?

Part of: metathalamus and vestibulo-auditory system.

Is the medial geniculate 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.
