An Anatomical Study of the Projection Region of the Dome of the Pleura to the surface of the Anterior Neck. (Part II). Geographical Relationship with the Sternocleidomastoid Muscle, Clavicle, and Acupuncture Points of the Lower Anterior Neck / 全日本鍼灸学会雑誌

Twenty-six domes of the pleura of thirteen cadavers were investigated. The summits of all domes protruded above the clavicle. Mediolateral positions of the summits were located between the lateral edge of the origin of the sternal head of the sternocleidomastoid muscle (CL3) and the lateral edge of the origin of its clavicular head (CL5), and their craniocaudal positions were located between the Point “Suitotsu” (S₁₀) and the medial edge of the origin of the clavicular head (CL4). The lateral edges of the domes did not reach the level of the clavicle. Their mediolateral positions were located between CL4 and the Point “Ketsubon” (S₁₂), and their craniocaudal positions were located between CL5 and the sternal extremity of the clavicle (CL2). The medial edges of the domes were both mediolaterally and craniocaudally located between CL2 and the suprasternal point. Projection regions of the domes of the pleura to the surface of the anterior neck were included, in all cases, within the quadrate region connecting the following four points: the Point “Suitotsu” (S₁₀), a point of intersection between the median line and a line drawn vertically from the Point “Suitotsu” (S₁₀) toward the median line, the suprasternal point, and a point on the clavicle corresponding to the medial one-third of the half shoulder width.
