Review of The Cranial Nerves

The Peripheral Nervous System The Peripheral Nervous System includes everything other than the brain and the spinal cord. It is broken down into 2 distinct.

Peripheral Nervous System - consists of the nerves that branch out from the CNS and connect it to other body parts, also includes the cranial nerves Somatic.

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)
