Whenever one turns the pages of a book, use a pen to take notes, or raise one's hand, this is possible due to the nervous system?

I believe the answer is: Somatic nervous system

Somatic nervous system refers to the nervous system that enable our body to make voluntary movement by using our sensory nerves and our motor nerves. Examples of actions that utilize this system are things such as turning pages, walking, running, jumping, eating, etc.
