Peripheral nerves can be divided into sensory, motor and autonomic, based on their function. The sensory nerves carry impulses from the nerve ending in the skin, muscle, or joints to the spinal cord and brain. On the other hand, the motor nerves extend from certain areas in the brain or spinal cord to different muscles. The autonomic nerves regulate blood pressure, heart rate, sweating and body temperature, among other functions. Neuropathy is characterized by dysfunction of the peripheral nerves. Depending on the location and the type of the nerve fibers involved, patients with neuropathy can have different symptoms.
