Sensory neurons send signals:

• toward your brain and spinal cord

• away from your brain and spinal cord

Motor neurons send information:

• from your brain and spinal cord toward your muscles

• from your body toward your spinal cord and brain, carrying information

This diagram shows that:

• your nervous system is made up of your stomach, lungs, and other organs

• nerves that come from different levels in your spine send messages to and from different organs

This diagram shows:

• a reflex arc

• a sensory neuron

• a motor neuron

Reflex arcs are a type of neural pathway that:
