“In case you’re still wondering — this is called the suprasternal notch.”
I was hunting down Fraser's suprasternal notch he really doesn't expose it very often and got carried away:
Although readily felt in the posterior triangle, it was impalpable on deep pressure in the suprasternal notch, a fact which seemed in favour of localising the aneurismal varix to the subclavian artery and vein.
The anterior supraclavicular nerves (nn. supraclaviculares anteriores; suprasternal nerves) cross obliquely over the external jugular vein and the clavicular and sternal heads of the Sternocleidomastoideus, and supply the skin as far as the middle line.
Besides distributing branches to the Sternocleidomastoideus, Subclavius, and neighboring muscles, it gives off a suprasternal branch, which crosses over the sternal end of the clavicle to the skin of the upper part of the chest; and an acromial branch, which pierces the Trapezius and supplies the skin over the acromion, anastomosing with the thoracoacromial artery.
Between these two layers is a slit-like interval, the suprasternal space (space of Burns); it contains a small quantity of areolar tissue, the lower portions of the anterior jugular veins and their transverse connecting branch, the sternal heads of the Sternocleidomastoidei, and sometimes a lymph gland.
Pallor, restlessness, startled awakening after a few minutes sleep, occurring in a child with croupy cough, indrawing around the clavicles, in the intercostal spaces, at the suprasternal notch and at the epigastrium, call for tracheotomy which should always be low.
A midline incision dividing the skin and fascia is made from the thyroid notch to just above the suprasternal notch.
The characteristic signs are inspiratory indrawing of the supraclavicular fossae, the suprasternal notch, the epigastrium, and the lower sternum and ribs.
If swelling or the size of the foreign body be sufficient to produce dyspnea, inspiratory indrawing of the suprasternal notch, supraclavicular fossae, costal interspaces and lower sternum will be present.
