The incomparable Asimov again! Here is the ideal reference book for anyone interested in finding out quickly and as accurately as present knowledge admits about major aspects of the bio-chemical functioning of our hormones, pancreas, thyroid, adrenal cortex, gonads, nerves, nervous system, cerebrum, brain stem, spinal chord, senses, cars, eyes, reflexes; and the processes of learning, reasoning, and memory-- major aspects of the mind. The above listing of the chapter headings (for the most part) indicates clearly that it is not only the brain that is described here. Actually, this is the second or companion volume to Asimov's earlier book The Human Body, which described the individual organs of the body. This book focuses on the organization and integration of bodily functions under the guidance and command of the hormones and the brain. Not a book to read through, but one for consultation and study. Though much valuable information is here for the high school student, some of the biochemistry is a bit too advanced for those with only basic knowledge of biology and chemistry. There are pronunciation guides for specialized terminology and the text is illustrated by the fine drawings of Anthony Ravielli. Certainly necessary for any library having the previous volume, and vital to any collection with even a minor interest in human biology.
