Final answer:
The cerebellum is the part of the brain responsible for coordinating movement and maintaining balance. It is essential for learned motor skills like hitting a ball or typing.
Step-by-step explanation:
The part of the brain that is responsible for coordination during movement is the cerebellum. The cerebellum is located below the cerebrum and behind the brain stem. It plays a crucial role in coordinating body movements, maintaining balance, and learning new motor tasks, such as when you hit a softball with a bat or type on a keyboard. It is not to be confused with other parts of the brain like the cerebral cortex or the brain stem, as each has its specific functions. For instance, the cerebral cortex is involved in abstract thought, problem-solving, and planning, but when it comes to coordination during movement, the cerebellum is the key player.
