For students, a good way to test their understanding and knowledge about a particular subject
and to prepare for exams is to practice using Multiple Choice Questions (MCQs). This book on
MCQs for Netter’s Head and Neck Anatomy for Dentistry has been written keeping in mind the
above purpose.
In this book Elsevier has worked with professional question writers to prepare a collection of
500 MCQs to accompany the subject matter covered in each chapter of the textbook, Netter’s
Head and Neck Anatomy for Dentistry, 2nd edition by Neil S. Norton (ISBN: 978-1-4377-2663-3).
The style of MCQs is three distractors and one correct answer so the student will need to mark
the correct option accordingly. Each chapter is followed by a feedback section showing the correct
answers and a very quick rationale why each answer is correct or incorrect thus elevating student’s
confidence to answer many more MCQs on the subject. Below each rationale, reference to the
page number of the main textbook, Netter’s Head and Neck Anatomy for Dentistry, is given for the
students who want to revise or study the particular topic again.
The aim for the student is to get as many correct as possible, and to revise any subject area
where the number of correct marks is low. We sincerely hope that students will find the book
extremely useful. We welcome comments and suggestions from students and teachers, which will
help in improving this book further.
