Neuropathy is used to describe nerve problems in the peripheral area of the Nervous system. The Central Nervous System is composed of the brain and spinal cord. Nerve problems can result from underlying health conditions, such as diabetes. Three nerve types can be affected – sensory nerves, motor nerves, or autonomic. Neuropathy may be limited to a particular set of nerves. Bell's Palsy is a condition which affects the nerves and muscles of the face.
