This series of brilliant photographs shows the dissection of the cat musculature. It is designed for use in conjunction with the third edition of Hyman's Comparative Vertebrate Anatomy, edited by Marvalee Wake, although it can be used with other textbooks. Every possible step has been taken to make the photographs easy to interpret and to follow. Reference indications to the Wake texts are included, and also concise data on the origin, insertion, and action of each muscle. The scale is such that in most cases no more than five muscles are shown per photograph, thus simplifying the task of visualizing the individual muscles. An invaluable aid for every student of cat anatomy.
The technique of electromyography, used to study the electrical currents generated by muscle action, has become invaluable to researchers in the biological, medical, and behavioral sciences. With it, the scientist can study the role of muscles in producing and controlling limb movement, eating, breathing, posture, vocalizations, and the manipulation of objects. However, many electromyographic techniques were developed in the clinical study of humans and are inappropriate for use in research on other organisms—tadpoles, for example. This book, a complete and very practical hands-on guide to the theoretical and experimental requirements of electromyography, takes into account the needs of researchers across the sciences.
John Fair and David Chapman tell the story of how filmmakers use and manipulate the appearance and performances of muscular men and women to enhance the appeal of their productions. The authors show how this practice, deeply rooted in western epistemological traditions, evolved from the art of photography through magic lantern and stage shows into the motion picture industry, arguing that the sight of muscles in action induced a higher degree of viewer entertainment. From Eugen Sandow to Dwayne “The Rock” Johnson, muscular actors appear capable of performing the miraculous, and with the aid of stuntmen and filming contrivances, they do. By such means, muscles are used to perfect the art of illusion, inherent in movie-making from its earliest days.
There is no part of our bodies that fully rotates—be it a wrist or ankle or arm in a shoulder socket, we are made to twist only so far. And yet there is no more fundamental human invention than the wheel—a rotational mechanism that accomplishes what our physical form cannot. Throughout history, humans have developed technologies powered by human strength, complementing the physical abilities we have while overcoming our weaknesses. Providing a unique history of the wheel and other rotational devices—like cranks, cranes, carts, and capstans—Why the Wheel Is Round examines the contraptions and tricks we have devised in order to more efficiently move—and move through—the physical world.
Steven Vogel combines his engineering expertise with his remarkable curiosity about how things work to explore how wheels and other mechanisms were, until very recently, powered by the push and pull of the muscles and skeletal systems of humans and other animals. Why the Wheel Is Round explores all manner of treadwheels, hand-spikes, gears, and more, as well as how these technologies diversified into such things as hand-held drills and hurdy-gurdies. Surprisingly, a number of these devices can be built out of everyday components and materials, and Vogel’s accessible and expansive book includes instructions and models so that inspired readers can even attempt to make their own muscle-powered technologies, like trebuchets and ballista.
Appealing to anyone fascinated by the history of mechanics and technology as well as to hobbyists with home workshops, Why the Wheel Is Round offers a captivating exploration of our common technological heritage based on the simple concept of rotation. From our leg muscles powering the gears of a bicycle to our hands manipulating a mouse on a roller ball, it will be impossible to overlook the amazing feats of innovation behind our daily devices.
