The anterior triangle is a region of the neck.
Boundaries
It is bounded, in front, by the middle line of the neck; behind, by the anterior margin of the Sternocleidomastoideus; its base, directed upward, is formed by the lower border of the body of the mandible, and a line extending from the angle of the mandible to the mastoid process; its apex is below, at the sternum.
Divisions
This space is subdivided into four smaller triangles by the Digastricus above, and the superior belly of the Omohyoideus below.
These smaller triangles are named:
* the muscular triangle
* the carotid triangle
* the submandibular triangle
* the submental triangle
