What is the role of the brain in the human nervous system?
It acts as the connection between nerves.
It serves as the control centre.
It connects the body to the external environment.
It pumps blood to the nerves.
What does the spinal cord do in the human nervous system?
It acts as the control centre.
It serves as the peripheral connection.
It acts as the connection between the brain and other nerves of the body.
It controls the digestive system.
Which two parts make up the Central Nervous System (CNS)?

What is the function of the Peripheral Nervous System (PNS)?
It controls the brain's functions.
It connects the brain and spinal cord with other parts of the body.
