cerebellar hemisphere

A paired regions of the cerebellum that lie outside and lateral to the central vermis[MP]. The cerebellum consists of three parts, a median and two lateral, which are continuous with each other, and are substantially the same in structure. The median portion is constricted, and is called the vermis, from its annulated appearance which it owes to the transverse ridges and furrows upon it; the lateral expanded portions are named the hemispheres. The lateral hemisphere is considered the portion of the cerebellum to develop most recently. [WP,unvetted]. Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the cerebellar hemisphere is

A paired regions of the cerebellum that lie outside and lateral to the central vermis[MP]. The cerebellum consists of three parts, a median and two lateral, which are continuous with each other, and are substantially the same in structure. The median portion is constricted, and is called the vermis, from its annulated appearance which it owes to the transverse ridges and furrows upon it; the lateral expanded portions are named the hemispheres. The lateral hemisphere is considered the portion of the cerebellum to develop most recently. [WP,unvetted]. The atlas records it as a nerve at the organ scale in the human body.

Where the cerebellar hemisphere is

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

What the cerebellar hemisphere connects to

The atlas records 18 typed relationships for it, across 5 kinds of connection. part of cerebellar cortex and material anatomical entity.

Supply and innervation

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

Questions

Where is the cerebellar hemisphere?

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

What does the cerebellar hemisphere connect to?

Part of: cerebellar cortex and material anatomical entity.

Is the cerebellar hemisphere 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.
