1. Autonomic system
The portion of the peripheral nervous system that stimulates smooth muscle, cardiac muscle, and glands; consists of the parasympathetic and sympathetic systems.

2. Guillain-Barre Syndrome (acute idiopathic polyneuritis)
A rare disease in which the body's immune system attacks the nerves of the peripheral nervous system , damaging the protective myelin sheath s surrounding the nerves and sometimes damaging the nerve axon s. Symptoms have a range of severity and can include abnormal sensations (such as numbness, pins and needles, vibrations, etc.), muscle weaknesses (due to the destruction of the nerves which carry signals to the affected muscles), aches and pains, and paralysis. The cause of Guillain-Barre Syndrome is unknown; often it is triggered by a virus infection (like hepatitis , mononucleosis , etc.). The disease occurs in both sexes and at any age. Treatment for the disease consists of treating the different symptoms as they arise and rehabilitation. Most patients (around 90%) recover without serious long-term disabilities between six months and two years after the syndrome begins. The 1-5% death rate is usually due to respiratory or cardiovascular complications.

3. Leprosy (Hansen's disease)
A chronic disease that causes lesions on the bones, skin, mucous membranes, and peripheral nervous system. People suffering from leprosy often lose sensation in their limbs and extremities because of nervous system lesions, and can unknowingly injure themselves and/or not care for wounds, thus causing further disfigurement. This disease, which was widely feared in ancient times and is still a problem in undeveloped countries, is caused by the Gram-positive , rod-shaped bacterium Mycobacterium leprae. Armadillos can also catch this disease (there have been a few isolated incidents of people catching leprosy from them) and so are used in medical research on the illness.

4. Motor (efferent) pathways
The portion of the peripheral nervous system that carries signals from the central nervous system to the muscles and glands.

5. Peripheral nervous system (PNS)
The nervous system beyond the brain and spinal cord . The nerves in this system connect the central nervous system (the brain and spinal cord) to sensory organs, body organs, blood vessels, glands and muscles.

6. Peripheral nervous system
The division of the nervous system that connects the central nervous system to other parts of the body. Components of the nervous system that transmit messages to the central nervous system.

7. Sensory (afferent) pathways
The portion of the peripheral nervous system that carries information from the organs and tissues of the body to the central nervous system .

8. Somatic nervous system
The portion of the peripheral nervous system consisting of the motor neuron pathways that innervate skeletal muscles .
