Which term refers to a posterior fossa structure that includes a vermis and two lateral horns?

Explanation:
Think about the posterior fossa anatomy. The vermis is the midline part of the cerebellum, with two lateral hemispheres on either side. A structure in the posterior fossa that includes a vermis and two lateral hemispheres is the cerebellum. The cerebrum sits above in the supratentorial space and doesn’t have a vermis, while the pons and medulla oblongata are brainstem parts and also don’t contain a vermis with two lateral hemispheres.
