Outline neurons
work as communication pathways from the brain to and from the body
they communicate by transmitting signals both electrically and chemically
Describe motor neurons
control muscle movement
when stimulated release neurotransmitters which bind to receptors on muscles to trigger response
Describe sensory neurons
found in receptors: eyes, ears, tounge
carry nerve impulses to spinal cord and brain, which is translated into sensations
Describe relay neurons
found in brain and spinal cord
between sensory input and motor output
allow neurons to communicate
