This book will prove interesting and profitable reading to the physiologist and clinician interested in cardiovascular problems in health and disease. Many of the older physiologists will find it necessary to change their interpretation of many vascular and cardiac phenomena on the basis of the pressoreceptor reflexes resulting from stimulation of the aortic and carotid sinus nerves (and perhaps others distributed to other larger vessels of the arterial circulation). The reflexes are described in terms of their comparative anatomy, physiology, pathology and pharmacology. The book is well written by one who has added his share to the knowledge of the quantitative aspects of the physiologic responses discussed in the volume. A comprehensive bibliography is appended. The clinician will find the book of practical interest and significance in his daily work.
