The peripheral nervous system (PNS) is a complex network of nerves that extends from the brain and spinal cord to the rest of the body, including muscles, organs, and skin. It consists of two main divisions: the somatic nervous system and the autonomic nervous system.
The somatic nervous system controls voluntary movements and sensory information from the body's external environment. It is responsible for functions such as muscle movement, touch, and temperature regulation. The autonomic nervous system, on the other hand, regulates the body's internal environment and controls involuntary functions such as heart rate, digestion, and breathing.
The PNS is susceptible to damage from a variety of sources, including injury, infection, and certain diseases. Peripheral neuropathy is a condition that affects the nerves of the PNS, causing symptoms such as tingling, numbness, and muscle weakness. Some common causes of peripheral neuropathy include diabetes, alcoholism, and certain medications. Treatment for peripheral neuropathy depends on the underlying cause, but may include medication, physical therapy, and lifestyle changes.
