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 the [[Sternocleidomastoideus]], 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]]. ==External links== * {{NormanAnatomy|lesson6}} {{Gray's}} {{Neck general}} [[Category:Head and neck]]
