  7. Sensory, Motor, and Mixed • 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)
