Answer 1

Explanation:

Parts and functions

The brain has three main parts: the cerebrum, cerebellum and brainstem.

• Cerebrum: is the largest part of the brain and is composed of right and left hemispheres. ...It performs higher functions like interpreting touch, vision and hearing, as well as speech, reasoning, emotions, learning, and fine control of movement.
• Cerebellum: is located under the cerebrum. ...The cerebellum receives information from the sensory systems, the spinal cord, and other parts of the brain and then regulates motor movements.
• Brainstem: acts as a relay center connecting the cerebrum and cerebellum to the spinal cord.The brainstem has many basic functions, including regulation of heart rate, breathing, sleeping, and eating. It also plays a role in conduction.

The central nervous system includes the brain and spinal cord, while the peripheral nervous system includes all of the nerves that branch out from the brain and spinal cord and extend to other parts of the body including muscles and organs.
