Isaac Asimov | 1965 | ISBN: | English | 330 pages | PDF | 61 MB
With his usual clear, informal style and meticulous attention to technical detail, Isaac Asimov concludes the study of the human organism that he began in The Human Body. In this volume the author considers the means by which the separate activities of various organs are controlled and coordinated into a harmonious whole -a functioning human being.
Dr. Asimov first discusses the hormone-secreting glands: pituitary, adrenal, thyroid, etc., and shows how this brain-controlled organization of "chemical messengers" regulates the body. Next he describes the nervous system step by step: the nerve cell, the spinal cord, the divisions of the brain, and finally the perceptions and responses of the human senses. In the last part of the book, Asimov considers the giant cerebral hemispheres-the human mind-and offers some fascinating speculation on its vast and unrealized potentials.
