Description[edit | edit source]
The neck, as a geometric region, can be clinically divided using anatomical triangles. The Sternocleidomastoid muscle obliquely crosses the neck to form the division between the two major neck triangles: anterior triangle and posterior triangle. Both triangles are further divided into smaller triangles: [1][2]
- Anterior Triangle
- Digastric/Submandibular Triangle
- Submental Triangle
- Carotid Triangle
- Muscular Triangle
- Posterior Triangle
- Occipital Triangle
- Subclavian/Supraclavicular
The neck is limited[1]:
- superiorly by the inferior border of the mandible
- anteriorly by midline
- inferiorly by the superior border of the clavicle
- posteriorly by the anterior margin of the trapezius muscle.
