Peripheral Neuropathy: When Signals in the Human Body Get Mixed Up

The peripheral nervous system is the human body’s vast communication system responsible for sending messages between the central nervous system (brain and spinal cord) to the rest of the body. Damage in these nerves will cause symptoms that range from muscle weakness to complete paralysis. The multitude of peripheral nerve networks are generally divided into three—sensory, motor and autonomic nerves. Sensory nerves are responsible for the sensations you feel on your skin, such as pain, touch, and temperature. Movement in the muscles of your arms and legs are possible due to the motor nerves. Autonomic nerves control the involuntary or hidden functions of your body like your heart rate, blood pressure, and digestion.
