• Sensory: afferent fibers that take information back to the brain• 5 senses: Smelling, seeing, tasting, hearing, touch• Proprioception: sense of where the body is in space
• Motor: efferent fibers that bring information from the brain• Movement
• Mixed: both sensory (afferent) and motor (efferent)
