This book teaches kids and adults both about the bones in the neck, the nerves that come out at each level as well as part of the body that these nerves control. It is a great book to teach us how connected we are and how proper alignment can bring proper function... especially in the neck as the upper neck is the most important part of our bodies! For more information on that subject, be sure to read, "One Bone, One Brain" and other books by Dr. Jamie. But until then, enjoy learning about the 7 bones in the neck!
