In the lung the oblique fissure (or major fissure) separates the inferior lobe of either lung from the remainder of the lung. (In the right lung it separates the inferior from the superior and middle lobe; in the left lung it separates the inferior and superior lobe as there is no middle lobe in the left lung.)The oblique fissure extends from the spinous process of T3 (posteriorly) to 6th costal cartilage (anteriorly).
