How is cerebellum divided?
How is cerebellum divided?
Like the cerebrum, the cerebellum is divided into two lateral hemispheres, which are connected by a medial part called the vermis. Each of the hemispheres consists of a central core of white matter and a surface cortex of gray matter and is divided into three lobes.
What are the primary anatomic components of the cerebellum?
The four deep nuclei of the cerebellum are the dentate, emboliform, globose, and fastigii nuclei and they act as the main centers of communication, sending and receiving information to and from specific parts of the brain.
What does the cerebellum do anatomy?
