This book offers a critical review of the head and neck from an anatomical, physiological and clinical perspective. It begins by providing essential anatomical and physiological information, then discusses historical and current views on specific aspects in subsequent chapters. For example, the anatomy of the skull cap or cranial vault provided in the first chapter is discussed in the context of malformation and identity, as well as the development of the bony skull, in the following chapters. These chapters provide stepping-stones to guide readers through the book. There are new fields of research and technological developments in which Anatomy and Physiology lose track of progress. One of the examples discussed is the automated face recognition. 

In some respects, e.g. when it comes to cancers and malformations, our understanding of the head and neck – and the resulting therapeutic outcomes – have been extremely disappointing. In others, such as injuries following car accidents, there have been significant advances in our understanding of head and neck dysfunctions and their treatment. Therefore head movements, also during sleep, and head and neck reflexes are discussed. The book makes unequivocal distinctions between correct and incorrect assumptions and provides a critical review of alternative clinical methods for head and neck dysfunctions, such as physiotherapy and lymphatic drainage for cancers. Moreover, it discusses the consequences of various therapeutic measures for physiological and biomechanical conditions, as well as puberty and aging. Lastly, it addresses important biomedical engineering developments for hearing e.g. cochlear implants and for applying vestibular cerebellar effects for vision.
