The Anterior region, on either side, may be subdivided into Supra-Clavicular, Clavicular, Infra-Clavicular, Mammary, and Infra-Mammary. Between these two regions we have the Supra-Sternal, Superior Sternal, and the Inferior Sternal. The Posterior region, on either side, may be subdivided into the Superior Scapular, Scapular, and Inferior Scapular. Between these you have the Inter-Scapular. The Lateral region, on either side, may be subdivided into Axillary, and Infra-Axillary regions.The Supra-Clavicular region is a triangle whose base corresponds to the trachea, lower side to the clavicle, upper side to a line drawn from the outer third of the clavicle to the upper rings of the trachea. This region contains, on either side, the apex of the lung, with portions of the subclavian and carotid arteries, and the subclavian and jugular veins.The Clavicular space is that which lies behind the inner three-fifths of the clavicle, and has the bone for its boundary. It is occupied on both sides by lung tissue- on the right side, at its outer extremity, lies the subclavian artery: at the steno-clavicular articulation, the arteria innominata. On the left side, almost at right angles with the bone, and deeply seated, are the carotid and subclavian arteries.The Infra-Clavicular region has for its boundaries, the clavicle above, the lower border of the third rib below, the edge of the sternum inside, and outside a line falling vertically from the junction of the middle and outer third of the clavicle.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
