Infraclavicular crossing of the 1st rib corresponds to which point?

Visceral-somatic reflex mapping uses surface points on the chest that correspond to internal organs. The nasal sinuses have an anterior reflex point located in the infraclavicular region, at the path where the first rib crosses beneath the clavicle. This anatomical landmark is used clinically because stimulating this point can influence autonomic input to the nasal mucosa and aid sinus drainage. Other ENT points, like those for the pharynx or larynx, map to different locations and are not at the first rib crossing. So, the infraclavicular crossing of the first rib corresponds to the nasal sinus anterior point.
