They were the first to discover that the nerve-trunks have their origin in the brain and spinal cord, and they are credited also with the discovery that these nerve-trunks are of two different kinds one to convey motor, and the other sensory impulses. They discovered, described, and named the coverings of the brain.
The pressure of improperly padded splints or other appliances may so far interfere with the circulation of the part pressed upon, that the skin sloughs, leaving an open sore. This is most liable to occur in patients who suffer from some nerve lesion such as anterior poliomyelitis, or injury of the spinal cord or nerve-trunks.
In some cases molluscum fibrosum is associated with pigmentation of the skin and with multiple tumours of the nerve-trunks. The small multiple tumours rarely call for interference. [Illustration: FIG.
So rapidly do these cells continue to breed and grow and spread resistlessly in every direction, that soon the entire gland, and next the neighboring tissues, become packed and swollen, so that a hard lump is formed, the pressure upon the nerve-trunks gives rise to shooting pains, and the first act of the drama is complete.
When medical treatment fails, the nerve-trunks may be injected with saline solution or recourse may be had to operative measures, the affected cords being exposed and stretched through an incision in the posterior triangle of the neck. If this fails to give relief, the more serious operation of resecting the posterior roots of the affected nerves within the vertebral canal may be considered.
Burns of the fifth and sixth degrees are met with in epileptics or intoxicated persons who fall into the fire. Large blood vessels, nerve-trunks, joints, or serous cavities may be implicated.
Thirdly, the tissues which give out this pain-cry under the torture of the toxins in the blood are, in a large majority of cases, neither the brain, nor the nerves of the eye, nor other special senses, but the nerves of common sensation which supply the face, the scalp, and the structures of the head generally, most of them derived from one great pair of nerve-trunks, the so-called Trigeminus, or fifth pair of cranial nerves.
