Overview
The horizontal fissure of right lung (or transverse fissure) is a fissure separating the superior lobe from the middle lobe.
The left lung has no middle lobe, so there is no horizontal fissure on that lung.
The Horizontal fissure usually extends from the oblique fissure along the border of the 4th rib.
