. Cunningham's Text-book of anatomy. Anatomy. Lower lobe Cardiac notch Fig. -The Trachea, Bronchi, and Lungs of hardened by formalin injection. Child, Groove for left . /innominate vein neck, short mit, and a groove, the sulcus subclavius, corresponding to the vessel, is apparent upon it. At a lower level on the apex pulmonis a shallower and wider groove upon its medial and ventral aspects marks the position of the innominate vein. Although these vessels impress the lung they are separated from it by the cupula pleurae. The diaphragmatic surface, or base of the lung, presents a semilunar outline, being curved around the base of the peri- cardium. It is adapted to the thoracic surface of the dia- phragm, and is consequently deeply hollowed out. As the right cupola of the diaphragm passes further upwards thaD the left, the basal concavity of the right lung is deeper than that of the left lung. Laterally and Groove for left subclavian artery dorsally, the dia- phragmatic surface of each lung is limited by a thin salient mar- gin, called the inferior border or margin, which extends downwards for some distance in a narrow pleural recess, the sinus phrenico- costalis, between the diaphragm and the chest-wall. This in- ferior border of the lung extends further downwards on the lateral side and dorsally than it does ventrally, but it falls- consider- ably short of the bot- tom of the phrenico- costal sinus. Thus, after expiration, it reaches the inferior border of the sixth rib in the mamillary line ; the eighth rib, in the axillary or mid-lateral line; whilst dorsally it proceeds medially along a straight horizontal line so as to reach the vertebral column at the level of the extremity of the spine of the tenth thoracic vertebra. During respiration the thin inferior border moves freely in a vertical direction within the phrenico- Groove for arch of aorta Left pulmonary artery Upper left pulmonary vein Left bronchus Lower left pulmonary vein - Groove for first rib Gro
