Overall this is an excellent and useful book. It is both concise and has a clear and easy to understand format. The content is arranged into units, each one is a bite sized chunk. There are a total of seven units, which vary in length from 15-40 pages each. Each unit is set out in a three stage manner with educational goals, study outline and finally self-testing.
The second edition now includes a new section consisting of an active learning guide, that contains written material and sketches to help aid learning for each of the seven units. The only minor criticism would be to rearrange the book so that the active learning guide for each section appears with the relevant unit, so that there would be an explanation followed by some testing. Having said that, this book is a great educational resource that is easy to read and organised in small enough sections to stop you from losing concentration.
The material is up to date and has been improved from the previous version. Generally it has a broad aim across a wide range of clinically allied students and practitioners. From a medical point of view it is aimed at junior doctors who are sitting their Diploma of Head and Neck exams and some junior registrars in the UK.
My impression of Anatomy and Physiology Study Guide for Speech and Hearing, 2nd edition is that it is a good book to lay down the foundation of the communication systems in an organised and well structured manner, that will help anyone who is new to this field.
