The submental triangle (or suprahyoid triangle) is a division of the anterior triangle of the neck.
Boundaries
It is limited to:
- Posterior (to the back) by the anterior belly of the digastricus,
- Anterior (to the front) by the midline of the neck between the mandible and the hyoid bone;
- Inferior (below) by the body of the hyoid bone while its floor is formed by the mylohyoideus.
Contents
It contains one or two lymph glands, the submental lymph nodes and some small veins; the latter unite to form the anterior jugular vein.
