There has been an interest in anatomy since ancient times. The skull and its precious content have always been some of the most fascinating and complex anatomic elements. The head and the neck include highly specialized parts of the body. The structures contained in them are closely related, being packed in an extremely small area. Plus, the head and neck area have an innervation that concerns the work of the dentist. Dentists deal with some nerves regularly; it is, therefore, important for the dentist to know the anatomical aspect linked with the head and neck. Anesthesia allows us to avoid any painful stimulus during the treatment. It was the basis for this Anatomy Compendium of the Nerves, focused on the ones of the oral cavity.
