New cards

axon

passes messages away from the cell body to other neurons

terminal branches of axon

form junctions with other cells

6
New cards

sensory neuron

carry incoming info from sensory receptors to the brain and spinal cord

7
New cards

motor neuron

carry outgoing information from brain and spinal cord to the muscles and glands

8
New cards

interneuron
