"The neck is that anatomical region that extends from the base of the skull posteriorly and above to the seventh cervical vertebra posteriorly and below, meanwhile in front from the mandibular angle above to the jugular notch below.
It is divided into two regions, a suprahyoid and an infrahyoid, based on the position of the hyoid bone. Additionally, it is separated by the cervical fascia."
