Controlling Body Systems

What is the nervous system?

• It is the network of nerve cells that transmit electrical signals throughout the body.

• It is the system that pumps blood through the veins and arteries.

• It is the structure that supports the skeletal framework of the body.

• It is the assembly of muscles responsible for movement.

What is the main cell of the nervous system that transfers signals to, from, and within the brain?

• Neuron

• Epithelial cell

• Red blood cell

What is the organ of the nervous system that transfers information between the brain and other parts of the body?

• The organ of the nervous system that transfers information between the brain and other parts of the body is the spinal cord.

• The brain is responsible for processing information.
