Depressor Anguli Oris

Interactive diagram of the muscles of the head, face and neck

The depressor anguli oris (also known as the triangularis menti) is a small triangular muscle of facial expression located in the lower-jaw area of the face on both sides of the chin / lower-mouth.

The points of origin and insertion, and the actions of the depressor anguli oris muscle:

Origin: External oblique line of the lower jaw (mandible)
Insertion: Angle of the mouth
Actions: Affects facial expression by moving skin tissues in the area of the lower jaw

Some of the fibres of the depressor anguli oris muscle are directly continuous with other adjacent muscles

The depressor anguli oris is one of the muscles of the head, neck, and face taught as part of many courses in Indian Head Massage. As this is a popular therapy we have included several pages that may be of interest to students of Indian Head Massage. See, for example, the page about skeletal structures of the head and neck.

See the page about Facial Muscles to view the location of the depressor anguli oris muscle.
(This page consists of an interactive, rather than just a labelled, diagram, so you'll have to test yourself by guessing which muscle is the depressor anguli oris until you find the correct label.)
