Quains Elements Of Anatomy Volume Iii Part Ii The Nerves PDF Download

Excerpt from Quain's Elements of Anatomy, Vol. 3 of 3: Part II. The Nerves IN this section is comprised the descriptive anatomy of the cerebro-spinal and sympathetic nerves, and their ganglia. Together with these the peripheral division of the nervous system also includes the organs of the external senses, which will be described in the following section. The minute structure of the nerves and their mode of ending in the several tissues and organs of the body are discussed in the sections General Anatomy and Splanchnology. The separation of the sympathetic from the cerebro-spinal nerves is convenient for purposes of description, but does not indicate a difference of origin or an anatomical independence of the two systems, since the fibres composing the sympathetic are connected centrally, either directly or indirectly, with the cerebro spinal axis, which they leave as constituents of the roots of certain of the cerebro spinal nerves. Moreover, the division cannot in all cases be strictly maintained, for some of the ganglia (ciliary, spheno-palatine, otic, and submaxillary), which are described in connection with the cranial nerves to which they are attached, have a close affinity with those of the sympathetic system, while on the other hand many of the terminal plexuses distributed to the viscera, and generally regarded as parts of the sympathetic system, are composed in large part of fibres which pass into them directly from cerebro-spinal nerves without traversing the cord of the sympathetic.
