Anatomists use the term triangles of the neck to describe the divisions created by the major muscles in the region.
The side of the neck presents a somewhat quadrilateral outline, limited, above, by the lower border of the body of the mandible, and an imaginary line extending from the angle of the mandible to the mastoid process; below, by the upper border of the clavicle; in front, by the middle line of the neck; behind, by the anterior margin of the trapezius.
The use of the divisions described as the triangles of the neck permit the effective communication of the location of palpable masses located in the neck between healthcare professionals.
