Abstract: "Chordates comprise all vertebrates plus a variety of unfamilar, distantly related and crucially important lineages (sea squirts, acorn worms, others). This book will be the first volume to synthesize and summarize what is known of the organization, development, homology and evolution of the muscles of all chordate animals. Muscles as different as those used by sea squirts and for human facial expression will be included. For the first time muscles of the entire body and both the pectoral and pelvic regions will be reviewed."--Provided by publisher
