Three basic types of neurons
Motor
Sensory
Interneurons
Sensory neurons
Afferent neurons
Carry sensory impulses from the peripheral sense organs towards the brain
Motor neurons
Efferent neurons
Transmit impulses away from the CNS
Cause muscle contractions/movement
Interneurons
Most common type of neuron
Link neurons with other neurons
Play an important role in controlling movement
The Peripheral Nervous System is made up of

Spinal nerves
Autonamic nervous system (sympathetic and parasympathetic)
The Central Nervous System is made up of
Spinal Cord
Brain
