Nervous System - Part 1

What does the axon carry?

• Impulses away from the cell body

• Impulses to the cell body

• chemicals

• messages

What do the motor neurons do?

• carry messages from the brain and spinal cord to muscles and glands

• carry impulses from skin and sends to organs the to spinal cord and brain

• carry impulses from sensory neurons to motor neurons

• store messages

What is the chemical used by a neuron to transmit an impulse across a synapse to another nerve cell?
