The correct spelling of the term referring to the smaller part of the brain is "cerebellum". The word comes from the Latin "cerebellus" meaning little brain. The phonetic transcription of this word in International Phonetic Alphabet is /ˌsɛrəˈbɛləm/. The cerebellum is responsible for voluntary muscle movements, balance, and coordination, and any damage to this part of the brain can have a significant impact on a person's ability to perform fine motor tasks. Thus, it is important to spell and pronounce this word correctly to avoid confusion or misunderstandings in medical contexts.
The "little brain" is a colloquial term used to refer to a specific structure in the brain known as the cerebellum. It is an integral part of the central nervous system, situated at the base of the brain beneath the cerebral hemispheres. Despite its modest size compared to the rest of the brain, the cerebellum plays a crucial role in coordinating voluntary movements, maintaining posture, and regulating balance.
The cerebellum is composed of two hemispheres and a central region called the vermis. It consists of an intricate network of neurons, known as Purkinje cells, which form dense layers and are essential for its functions. By receiving sensory information from various parts of the body, the cerebellum assists in refining movements and ensuring their accuracy, strength, and fluidity.
In addition to motor function, the cerebellum also contributes to cognitive processing, including attention, language, and abstract reasoning. Any damage or disorders affecting the cerebellum can result in noticeable deficits in motor coordination, muscle control, and balance.
While the term "little brain" is not a medical or scientific designation, it reflects the cerebellum's smaller size compared to other brain regions. However, the significance of this structure in supporting motor skills and certain cognitive functions should not be underestimated.

The word "little brain" comes from the Latin phrase "cerebellum", which means "small brain" in Latin. The term was coined by Galen, a Greek physician and anatomist, in the 2nd century AD, who noted the similarities between the cerebellum and the brain but observed that the cerebellum was smaller in size. Thus, the term "little brain" or "cerebellum" was used to describe this specific part of the brain.
