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.

This anatomy section promotes the use of the Terminologia Anatomica, the international standard of anatomical nomenclature.

Superficial head and neck

• nasal cavity
• oral cavity
• pharynx
  • oropharynx
  • nasopharynx
  • hypopharynx
• larynx

Deep head and neck

The deep anatomy is separated by fascial planes into seven deep compartments of the head and neck:

• pharyngeal (superficial) mucosal space
• parapharyngeal space
• parotid space
• carotid space
• masticator space
• retropharyngeal space
• perivertebral space

Many of the disease states that affect the deep structures of the head and neck are confined to one compartment. However, there are some diseases that are considered trans-spatial diseases.

Surgical triangles of the neck

There are several triangles of the neck that are more surgically focused, first described from early dissection-based anatomical studies which predated cross-sectional anatomical description based on imaging:

• anterior triangle
  • digastric triangle
  • carotid triangle
  • muscular triangle
  • submental triangle
• posterior triangle
  • occipital triangle
  • supraclavicular triangle
