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)?

• Brain and heart

• Spinal cord and peripheral nerves
