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 sub-triangles: [1][2]
- Anterior Triangle
- Digastric/Submandibular Triangle
- Carotid Triangle
- Muscular Triangle
- Submental Triangle
- Posterior Triangle
- Occipital Triangle
- Subclavian/Supraclavicular
The neck is limited[1]:
- superiorly by the inferior border of the mandible
- anteriorly by midline of the neck
- inferiorly by the superior border of the clavicle
- posteriorly by the anterior margin of the trapezius muscle.
Anterior Triangle[edit | edit source]
- Superior border - inferior border of mandible
- Medial border- midline of neck
- Lateral border- anterior border of sternocleidomastoid muscle
The Anterior Triangle has an apex that extends to the manubrium of sternum. It is made up of three paired triangles: submandibular (digastric), carotid, and muscular (omotracheal/infrahyoid) triangles, and one unpaired triangle: submental triangle.
