According to most sources, there is no middle lobe in the left lung as there is in the right lung. However, the term lingula is used to denote a projection of the upper lobe of the left lung that serves as the homologue, and some sources define this as a distinct lobe.
There are two bronchopulmonary segments of the lingula: Superior and inferior.
It is thought that the lingula of the left lobe is the remnant of the middle lobe of the left lung, which has been lost through evolution.
