PDF-(EBOOK)-Structure and Evolution of Invertebrate Nervous Systems

The nervous system is particularly fascinating for many biologists because it controls animal characteristics such as movement behavior and coordinated thinking Invertebrate neurobiology has traditionally been studied in specific model organisms whilst knowledge of the broad diversity of nervous system architecture and its evolution among metazoan animals has received less attention This is the first major reference work in the field for 50 years bringing together many leading evolutionary neurobiologists to review the most recent research on the structure of invertebrate nervous systems and provide a comprehensive and authoritative overview for a new generation of researchers Presented in full colour throughout Structure and Evolution of Invertebrate Nervous Systems synthesizes and illustrates the numerous new findings that have been made possible with light and electron microscopy These include the recent introduction of new molecular and optical techniques such as immunohistochemical staining of neuronspecific antigens and fluorescence insituhybridization combined with visualization by confocal laser scanning microscopy New approaches to analysing the structure of the nervous system are also included such as microcomputational tomography cryosoft Xray tomography and various 3D visualization techniques The book follows a systematic and phylogenetic structure covering a broad range of taxa interspersed with chapters focusing on selected topics in nervous system functioning which are presented as research highlights and perspectives This comprehensive reference work will be an essential companion for graduate students and researchers alike in the fields of metazoan neurobiology morphology zoology phylogeny and evolution.

The nervous system uses specialized cells called neurons to send signals or messages all over the body. These electrical signals travel between the brain, skin, organs, glands and muscles.. Pd-2 . Anatomy and Physiology. Evidence for evolution can come in the form of anatomy and physiology. For example vestigial, analogous, and homologous structures. . Vestigial Structure:. The concept of vestigiality applies to genetically determined structures or attributes that have apparently lost most or all of their ancestral function in a given species. An example is the human appendix.. Concept 49.1. Mary Kathryn Pearson, Susan Sabatier, and Olivia Johnson. Simple Nervous Systems. In most animals with nervous systems, clusters of neurons perform specialized functions. . Such clustering is absent in the cnidarians, the simplest animals with nervous systems. .
