The brain itself is almost totally insensitive to pain. The scalp, arteries, muscles, mucous membranes of the sinuses, ear, and the teeth are all pain-sensitive structures. The crucial areas in the creation of headache are the suboccipital and upper cervical areas as well as the scalp. In the upper two cervical segments, the sensory fibers of the first three cervical segments are joined by the descending tracts of cranial nerves V, IX, and X. These three cranial nerves, along with the second cervical nerve, mediate the referral of excessive coimective tissue tension in the cervical area as pain in the cranial vault or cephalgia.
