Views of segmental bronchi, azygos system of veins, sympathetic trunks and costovertebral joints
Segmental bronchi of left lung in relation to branches of pulmonary artery, lateral view
The dissection has been prepared, in a manner similar to that for the right lung (126A-1), to demonstrate the relations of the pulmonary artery and the bronchi in the left lung. In the following view (126-4) the segmental divisions of the bronchi are shown after removal of the left pulmonary artery.
Rib I
Anterior branch left pulmonary artery
Upper pointer: Anterior segmental bronchus Lower pointer: Superior lobar bronchus
Upper pointer: Superior lingular branch left pulmonary artery Lower pointer: Superior lingular bronchus left pulmonary artery
Location of left phrenic nerve (covered by pleura)
Upper pointer: Apical branch left pulmonary artery Lower pointer: Apicoposterior segmental bronchus (Note: the posterior ramus of the posterior subsegmental bronchus (no. 8, lower pointer) has an aberrant origin from the anterior segmental bronchus in this specimen)
Upper pointer: Posterior branch left pulmonary artery Lower pointer: Posterior branch of posterior subsegmental branch of segmental bronchus
Upper pointer: Interlobar part left pulmonary artery Lower pointer: Superior branch of inferior left pulmonary artery
