    OF GENERAL, DESCRIPTIVE, AND PATHOLOGICAL ANATOMY. DESCRIPTIVE ANATOMY. SECTION II. OF THE PERIPHERY OP THE NERVOUS SYSTEM. § 1809. The periphery of the nervous system, comprehending the nerves properly so called, is divided into three sections : the nerves of the spinal marrow or the spinal nerves, the nerves of the brain or the en- cephalic nerves, and the ganglionnary or great sympathetic nerve. The number of these nerves, including the last, is forty-three pairs. But anatomists do not divide them in the same manner, for several cerebral nerves have been blended which are now considered as distinct pairs ; and farther, some consider as cerebral nerves those which others refer to the spinal pairs. We shall point out the differences arising from the first of these sources in our general remarks on the cerebral nerves. Those which arise from the second depend principally upon the division of the central mass of the nervous system. If the medulla oblongata be considered as the summit of the spinal marrow, we must naturally arrange the nerves arising from it among the spinal pairs ; hence their number is increased, while that of the cerebral pairs is diminished.
