![Of the Accessory Nerve. The accessory nerve is found in man and the other mammalia. (PI. i. fig. 3, 4, 5, and pi. vi. fig. 1, 2—3.) It arises from the cervlco-spinal mass and medulla oblongata. Its filaments come from the dorsal surface of these parts, and vary- in number, in thickness, and in length, not only in difierent individuals of different species, but even on the two sides of the same subject. The first filaments are detached at various heights, sometimes higher, sometimes lower, in the spinal cord, issuing from the level of the seventh cervi- cal pair in one instance, and from that of the fifth in another. The accessory recedes from the spinal cord and medulla oblongata, as it ap- proaches the pneumogastric nerve, along with which it escapes from the cranium. I have al- ready said, that Mr. Charles Bell arranges the accessory among the nerves of respiration. In contributing to this function, it produces mo- tion, and is influenced by the will; nevertheless it is detached, as we have seen, from the dorsal surface of the spinal cord. Of the Pneumogastric Nerve. The pneumogastric occurs in all vertebral] ani- mals. In man (pi. vi. fig. 1, 6), it issues by nu-](https://iiif.wellcomecollection.org/image/b21078804_0102.jp2/full/800%2C/0/default.jpg)
