Muscular triangle

The muscular triangle is one of the paired triangles in the anterior triangle of the neck. The triangles of the neck are surgically focused, first described from early dissection-based anatomical studies which predated cross-sectional anatomical description based on imaging (see deep spaces of the neck).

Boundaries

• anterior: median line of the neck from the hyoid to the sternum
• inferoposteriorly: anterior border of sternocleidomastoid
• posterosuperiorly: superior belly of omohyoid

Contents

The muscular triangle contains the strap (infrahyoid) muscles, hence its name:

• omohyoid
• sternohyoid
• sternothyroid
• thyrohyoid
