Paperback. Condizione: New. Print on Demand. This book explores the fascinating world of animal color changes, focusing on the physiological mechanisms underlying these dynamic transformations. The author delves into the historical understanding of color changes, highlighting early observations and theories. The book examines two distinct types of color control in animals: nervous and hormonal. In the nervous system, the author explores the role of specific nerve fibers that induce pigment dispersion or concentration in chromatophores, the cells responsible for color changes. The hormonal control system, discussed in depth, reveals the influence of neurohumors, chemical messengers produced by the pituitary gland, on chromatophores. The author presents a novel view of chromatophoral nerves, challenging the traditional notion of nerve paralysis after cutting. Through innovative experiments, it is shown that severed nerves remain active, inducing prolonged pigment dispersion in melanophores, the dark pigment cells. The book concludes by emphasizing the significance of these findings for understanding the workings of the nervous system and the broader field of neurobiology. By unraveling the complex interplay between nerves and hormones in animal color changes, the author provides valuable insights into the mechanisms that govern these remarkable adaptations.
