brainstem

Stalk-like part of the brain that includes amongst its parts the medulla oblongata of the hindbrain and the tegmentum of the midbrain[ZFA,MP,generalized]. Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the brainstem is

Stalk-like part of the brain that includes amongst its parts the medulla oblongata of the hindbrain and the tegmentum of the midbrain[ZFA,MP,generalized]. The atlas records it as a nerve at the organ scale in the human body.

Where the brainstem is

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

What the brainstem connects to

The atlas records 59 typed relationships for it, across 6 kinds of connection. part of brain.

Supply and innervation

This dataset asserts no arterial supply, venous drainage or innervation for the brainstem. 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 brain stem, truncus encephali, accessory medullary lamina of pallidum, lamella pallidi incompleta, lamina medullaris accessoria and lamina medullaris incompleta pallidi, and 2 more. Searching any of those names reaches this page.

Questions

Where is the brainstem?

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

What does the brainstem connect to?

Part of: brain.

Is the brainstem 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.
