Which region of the body is defined by the term "cervical"?

The term "cervical" specifically refers to the neck region of the body. In anatomical terminology, "cervical" is derived from the Latin word "cervix," which means neck. This region connects the head to the thorax and contains important structures such as the cervical vertebrae, major blood vessels, and the trachea and esophagus, among others. Understanding this term is crucial for both anatomy studies and clinical applications, as it helps in identifying the location of injuries, diseases, or physical examinations related to the neck.
