cranial nerves, spinal nerves, and autonomic nervous system (i.e., nerves outside the central nervous system)
The nerves of the skull and the spine.
Nerves that run to and from the central nervous system (the brain and spinal cord) to and from all other areas of the body. The nerves carry sensory messages (such as touch and temperature) and motor messages, which make the tissues and organs of the body carry out their functions, e.g. muscles contract for movement.
The nerves after the departure from the spinal canal, proceeding out to their end point in the skin and muscles.
Nerves that run from your spinal cord to all other parts of your body. Peripheral nerves transmit messages from the spinal cord and the brain to and from other parts of your body, and send sensory signals back to the spinal cord and brain.
The nerves outside of the brain and spinal cord, including the autonomic, cranial, and spinal nerves. Peripheral nerves contain non-neuronal cells and connective tissue as well as axons. The connective tissue layers include, from the outside to the inside, the epineurium, the perineurium, and the endoneurium.
Nerves outside the brain and spinal cord. In the case of TN, these include the many branches of the trigeminal nerve that serve the teeth, gums and other parts of the face.
