The triangles of the neck 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 ...
The zonule of Zinn is split into two layers: a thin layer, which lies near the hyaloid fossa, and a thicker layer, which is a collection of zonular fibers. Together, the fibers are known as the suspensory ligament of the lens. [4] The zonules are about 1–2 μm in diameter. [5]
Inferior boundary (apex) Jugular notch in the manubrium of the sternum: Anterior boundary: Midline of the neck from chin to the jugular notch Posterior boundary: The anterior margin of sternocleidomastoid
