Anterior & Posterior Triangles of the Neck Muscles Poster

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. This space is subdivided into two large triangles by Sternocleidomastoid, which passes obliquely across the neck, from the sternum and clavicle below, to the mastoid process and occipital bone above. The triangular space in front of this muscle is called the Anterior triangle of the neck; and that behind it, the Posterior triangle of the neck.
