Final answer:
The cerebellum, meaning 'little brain' in Latin, is at the base of the brain and is key for balance, movement coordination, and motor learning.
Step-by-step explanation:
The structure whose Latin name means little brain and is located at the caudal part of the brain is called the cerebellum. It is located at the base of the brain on top of the brainstem and is responsible for controlling balance and aiding in the coordination of movement, as well as learning new motor tasks. Despite accounting for only about 10 percent of the brain's mass, the cerebellum contains over half of the brain's nerve fibers. It also plays a role in processing procedural memories, which are involved in learning and remembering how to perform tasks.
