- Medial (towards the midline), formed by the midline of the neck between the mandible and the hyoid bone
- Inferior (below), formed by the body of the hyoid bone
- Floor is formed by the mylohyoideus
- Roof is formed by investing layer of deep cervical fascia
Contents
It contains one or two lymph glands, the submental lymph nodes (three or four in number) and Submental veins and commencement of anterior jugular veins.
