Is the trigeminal nerve part of the central nervous system?
The trigeminal nerve is the largest and most complex of the 12 cranial nerves (CNs). It supplies sensations to the face, mucous membranes, and other structures of the head. It is the motor nerve for the muscles of mastication and contains proprioceptive fibers.
What autoimmune disease causes trigeminal neuralgia?
Trigeminal neuralgia has been traced to multiple sclerosis, an autoimmune disease in which the body attacks the myelin sheath, causing nerves to short-circuit. This leads many MS patients to complain of a tingling sensation in parts of their body.
Can trigeminal neuralgia be misdiagnosed?

Initial negative imaging should be repeated, given reports of tumor becoming visible several months after the onset of pain. The pathophysiology of this syndrome is believed to involve sympathetic and parasympathetic dysregulation.
What is the pathophysiology of atypical trigeminal dysregulation?
The pathophysiology of this syndrome is believed to involve sympathetic and parasympathetic dysregulation. Sympathetic secretomotor innervation of the parotid produces a small amount of thick saliva that inhibits secretion, whereas parasympathetic secretomotor input produces a large volume of watery saliva that stimulates secretion.
