amygdala

Subcortical brain region lying anterior to the hippocampal formation in the temporal lobe and anterior to the temporal horn of the lateral ventricle in some species. It is usually subdivided into several groups. Functionally, it is not considered a unitary structure (MM). Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the amygdala is

Subcortical brain region lying anterior to the hippocampal formation in the temporal lobe and anterior to the temporal horn of the lateral ventricle in some species. It is usually subdivided into several groups. Functionally, it is not considered a unitary structure (MM). The atlas records it as a nerve at the organ scale in the human body.

Where the amygdala is

It sits within the nervous system. Positioned deliberately as part of this species body plan.

What the amygdala connects to

The atlas records 19 typed relationships for it, across 3 kinds of connection. part of cerebral hemisphere, limbic system and temporal lobe.

Supply and innervation

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

Questions

Where is the amygdala?

It sits within the nervous system. Positioned deliberately as part of this species body plan.

What does the amygdala connect to?

Part of: cerebral hemisphere, limbic system and temporal lobe.

Is the amygdala 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.
