The suprasternal notch is a visible dip in between the neck, between the clavicles, and above the manubrium of the sternum. It is at the level of the T2 and T3 vertebrae. [2] The trachea lies just behind it, rising about 5 cm above it in adults. [3]

This space is covered by the integument, the superficial and deep fasciæ and the platysma, and crossed by the supraclavicular nerves. Just above the level of the clavicle, the third portion of the subclavian artery curves lateralward and downward from the lateral margin of the scalenus anterior , across the first rib , to the axilla , and this ...
This notch can be felt between the two clavicles. On either side of this notch are the right and left clavicular notches. [1] The manubrium joins with the body of the sternum, the clavicles and the cartilages of the first 1.5 pairs of ribs. The inferior border, oval and rough, is covered with a thin layer of cartilage for articulation with the ...
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 clavicle, collarbone, or keybone is a slender, S-shaped long bone approximately 6 inches (15 cm) long [1] that serves as a strut between the shoulder blade and the sternum (breastbone). There are two clavicles, one on each side of the body. The clavicle is the only long bone in the body that lies horizontally. [2]
The posterior triangle is crossed, about 2.5 cm above the clavicle, by the inferior belly of the omohyoid muscle, which divides the space into two triangles: an upper or occipital triangle; a lower or subclavian triangle (or supraclavicular triangle)
