Description:Excerpt from The Movements of Respiration: And Their Innervation in the Rabbit, With a Supplement on the Relation of Respiration to Deglutition, and on the Question of the Existence of Respiratory Centres in the Spinal Cord The innervation of the respiratory movements is well known to be one of great complexity, and there are many vague and unsatisfactory statements regarding it in current literature. More especially is this the case with reference to the questions as to whether there are respiratory centres in the spinal cord as well as in the medulla oblongata, and as to how far and in what manner these centres are influenced by nervous impressions flowing from the periphery of the body, or passing from the higher nervous centres downwards. In 1811, Legallois first demonstrated that an important centre for respiratory movements existed in the medulla oblongata, and Flourens, with whose name this discovery is usually associated, did little except to give to this centre the well-known name, n ud vital. Since then, physiological experiment has been chiefly occupied in limiting and defining this centre. Thus Longet, Charles Bell, Schiff, Giercke, and others, endeavoured to define with accuracy certain centres or bundles of nerve fibres as specially constituting the respiratory centre. The next step was made in 1860, when Brown-Sequard stated that respiratory movements might take place after removal of the medulla oblongata, and this statement was supported by Dr. Bennett-Dowler of New Orleans, who noted the fact in decapitated crocodiles, by Dr. B. W. Richardson, who made the observation on new-born mammals, and by Rokitansky, who, in 1876, noticed respiratory movements in decapitated young rabbits after the injection of strychnia. This led to a remarkable series of experiments by Langendorff, dating from 1880 to the present year, in which he accumulates facts in favour of the view that respiratory centres exist in the spinal cord, and that these can become active in a reflex or automatic manner. This, then, is one aspect of the problem of breathing. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
