This comprehensive textbook for undergraduate-level anatomy and physiology courses in communication sciences and disorders programs is neither oversimplified nor excessively detailed. The book is written with clinical endpoints in mind, and only those topics that are ultimately important to understanding, evaluating, and managing clients with speech, hearing, and swallowing disorders are covered. Drawn from the best-selling Preclinical Speech Science: Anatomy, Physiology, Acoustics, and Perception, Second Edition textbook (Hixon, Weismer, & Hoit, 2014), the authors distilled and simplified the chapters on breathing and speech production, laryngeal function and speech production, velopharyngeal-nasal function and speech production, pharyngeal-oral function and speech production, brain structures and mechanisms, and swallowing to ensure they are approachable for entry-level students. They also added a new chapter on the anatomy and physiology of the auditory system.
