The Anatomy and Physiology of the Mammalian Larynx

During this designated e-book, Sir Donald Harrison attracts on his wide-ranging adventure as a health care professional and comparative anatomist to supply an authoritative and distinctive account of the anatomy and body structure of the mammalian larynx. His research of the larynx has concerned the research of over 1200 specimens of mammalian larynges from around the globe, in addition to utilizing information from his personal scientific reviews.

ELF and VLF Electromagnetic Field Effects

Contemporary emphasis upon the significance of the actual surroundings has made technological know-how and the general public much more cog­ nizant of the various elements of the biosphere. whereas a lot recognition has been given to ionizing electromagnetic stimuli which factors blatant and unalterable alterations in organic platforms, really little learn has been keen on these electromagnetic indications whose frequencies overlap with time-varying procedures in residing organisms.

A Photographic Atlas for the Anatomy and Physiology Laboratory Seventh Edition

This full-color atlas is designed for all scholars taking separate or built-in classes in human anatomy and body structure. This atlas can accompany and increase any human anatomy, human body structure or mixed human anatomy and body structure textbook. it truly is designed to be of specific price to scholars in a laboratory state of affairs and will both accompany a laboratory guide or, in yes classes, it could actually function the laboratory guide.

Essential Clinically Applied Anatomy of the Peripheral Nervous System in the Limbs

Crucial Clinically utilized Anatomy of the Peripheral apprehensive approach within the Limbs is designed to mix the salient issues of the anatomy of the PNS with commonplace pathologies affecting the nerves of the higher and decrease limbs. The e-book is a short reference consultant for these learning and treating neuromuscular ailment akin to neurologists, neurosurgeons, neuroradiologists, and scientific neurophysiologists.

Example text

This may not be the case; nevertheless, the matter should be investigated, using modern electron-microscopic and cytological methods. No relevant study could be found in the literature surveyed. The present authors consider such carefully conducted studies as absolutely necessary for the acceptance of any explanation of the mechanism of the biological effects of microwaves, and stress the necessity for publication of eventual negative results. It should be stressed that an apparent discrepancy exists between the theoretical explanations available, the experimental results obtained on isolated components (biologically active molecules, membranes), and the effects observed in complex biosystems such as subcellular structures, cells, organs, systems, and whole intact organism.

4. Providing free energy of activation for a chemical reaction. The analysis of nonionizing radiation interaction with living systems made by Illinger 12421 is summarized in Fig. 40, taken from his paper. According to this author, the primary processes in this region are photon-induced absorption and emission and collision-induced absorption and emission. Thermal noise and spontaneous emission may be neglected for the microwave region. Rotational, vibrational, and relaxation phenomena lead to temperature increase as presented previously and no additional information is to be gained by quantum mechanical treatment.

46 with empirical results demonstrates that the calculated values are lower than the empirical ones for larger animals, both for dogs and man. Man is characterized by the high efficiency of his thermoregulatory mechanisms 1217, 2581. Calculated values are distinctly higher than empirical ones for mice [23, 251. These data may be used for preliminary planning of experiments on thermal effects of microwaves and microwave effects not accompanied by body-temperature increases. The difference between the calculated and empirical values may also be used for assessing the efficiency of the fhermoregulatory mechanisms of the species investigated (see also [24q).
