Head and neck anatomy

Head and neck anatomy is important when considering pathology affecting the same area. In radiology, the 'head and neck' refers to all the anatomical structures in this region excluding the central nervous system, that is, the brain and spinal cord and their associated vascular structures and encasing membranes i.e. the meninges. Many pathologies are confined to a particular area of the head and neck making separation of this section of the human body exceptionally useful.
