Nervous Force: Its Origin and Physiology (Classic Reprint)


Book Description

Excerpt from Nervous Force: Its Origin and Physiology Of the manner in which nerve force is eliminated we know little, but that it is in some way through the nerve centres we are convinced. Experiment has proved this, and at the same time established the fact of its close correlation to the other forces. When the nerve centers are destroyed or paralyzed, not only is the production of nerve force stopped, but the body quickly cools. Upon sending a current of electricity along the course of the nerves, the bodily heat or temperature rises, so closely are these forces connected. If an organic body be deprived of light, not only is nervous force diminished, but the temperature is lowered. We have all known persons whose hair during conditions of nervous excitement would stand on end, and from whom at such times could be drawn distinct electric shocks. I know a man who, by inducing a restless, agitated nervous state in favorable atmospheric condition, can light a gas jet by simply holding his finger tip to the burner. These states are always succeeded by nervous depression, undoubtedly due to a loss of nervous power. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Anatomy and Physiology of the Nervous System (Classic Reprint)


Book Description

Excerpt from Anatomy and Physiology of the Nervous System The preparation of this work has been undertaken in response to what experience in the class-room has shown to be the need of a text-book especially adapted to beginners - a book giving, by itself, a concise, but complete, presentation of the physiology of the nervous system, together with the more important features of its anatomy. In dealing with the physiological phase of the subject, it has seemed best, viewed from the students standpoint, to confine the statements mostly to the established and generally recognized facts, leaving the numerous theories - fully and admirably discussed in many contemporary works - to be taken up at a later stage of the study, after the facts have been acquired and mastered, this plan, it is found, being the most effective as a time-saver, and resulting in the clearest and most lasting impressions. The anatomical matter included in the volume is only that which seems most necessary fox an intelligent understanding of the physiology, and of the most frequent service in clinical work, the general text-book on anatomy always being available for further details. Both the structure and the various functions of the sympathetic system have been set forth with a fullness commensurate with their importance. Of the whole work condensation has been the guiding principle. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

The Origin and Development of the Nervous System


Book Description

Excerpt from The Origin and Development of the Nervous System: From a Physiological Viewpoint Since many different lines of investigation concerned in the discussion are of necessity mentioned only very briefly, it has seemed advisable to give references, so far as it could be done without unduly breaking the continuity of the text. The list of titles following the text makes no pretensions to completeness, but includes merely the publications to which reference is made.

The Nervous System, and Its Conservation (Classic Reprint)


Book Description

Excerpt from The Nervous System, and Its Conservation There are several excellent books devoted to the anat omy of the nervous system, there are others which treat of its physiology in an illuminating way, and others still which deal with its hygiene. If the present volume is not to be an impertinence, it must be justified by its attempt to combine some elements of the three. The intention has been to present no more anatomy than is essential to an appreciation of the correlated physiology and to subordinate the physiology, in its turn, to the teaching of hygiene. In the chapters which deal with structure and func tion the writer has tried to gather his material from authoritative sources. In those occupied more largely with hygiene, personal judgments have doubtless found expression. But the desire has been not so much to dictate in a dogmatic spirit as to open important mat ters to fuller discussion.

The Involuntary Nervous System (Classic Reprint)


Book Description

Excerpt from The Involuntary Nervous System I went to Leipsic in 1874 to Ludwig's Laboratory with the intention of working at problems connected with the sympathetic nervous system, and from that time until now my thoughts have been occupied with the meaning of this nervous system and with problems which have arisen from its study, such as the origin of the vertebrate central nervous system and thence the origin of the vertebrates themselves.

The Nervous System


Book Description

Excerpt from The Nervous System: An Elementary Handbook of the Anatomy, and Physiology of the Nervous System, for the Use of Students of Psychology and Neurology The steadily increasing application of physiological facts to problems in psychology, and the rapid development of the science of experimental psychology, have rendered it essential that the student of psychology should possess some knowledge of the anatomy and physiology of the nervous system of man. There are excellent articles on these in most of the recent textbooks of anatomy or of physiology, but generally the information is too detailed, and further, the student must of necessity purchase the complete book to acquire the desired article. In this small textbook an attempt has been made to present the essential features of the anatomy and physiology of the nervous system in a form sufficiently simple to be understood by a non-medical student. At the same time it is hoped that it will prove useful, as an introductory handbook, for students of medicine, or for those who desire to refresh their memories of the central tracts, in considering cases of neurological interest. The book makes no pretence of dealing with the application of the subject either to psychology or to neuro-pathology. It has been compiled from many sources but, obviously, it is impossible to acknowledge these individually. Most of the diagrams have been taken from 'Grays Anatomy' (17th edition) and a few from 'Quain's Anatomy' (11th edition), by the courtesy of the editors and publishers of these works. The other diagrams are either original or are modifications of well-known figures. The author desires to acknowledge with gratitude the great help he has received from Professor Howden, Professor of Anatomy in the University of Durham, under whose supervision the book has been written. He is also greatly indebted to Professor Robinson, Professor of Logic and Psychology in the University of Durham, who has kindly read over the MSS. and has generally defined the scope of the work.

Memoirs on the Physiology of Nerve, of Muscle and of the Electrical Organ (Classic Reprint)


Book Description

Excerpt from Memoirs on the Physiology of Nerve, of Muscle and of the Electrical Organ Hering rejects this theory on the ground that the changes of which positive polarisation' is the expression, have their seat exclusively at the anode, and explains the experimental facts used by du Bois in proof of 'internal polarisation' (that is of a polarisation affecting all traversed structures, and consisting in the coming into existence of electromotive forces all along the line of flow, and not merely at anodes or cathodes), on the sup position that he employs structures in which, in consequence of their heterogeneity, such sudden transitions from less to greater density occur in the course of the current-paths, that the effects of anodes are produced. On the assumption that positive polari sation has its seat at the anode exclusively, he has no difficulty in referring what is observed to the well-recognised facts (1) that the effect of Opening a current led through a muscle or nerve is to produce excitation at the anode; and (2) that the characteristic expression of the excitatory state is negativity; and accordingly, while recognising the essential relation of the change in question to the functional activity of the organ in which it manifests itself, he prefers to speak of it as 'anodic after efl'ect' rather than as positive polarisation.'
