Latin lingula pulmonis sinistri

The human left lung, unlike the right, contains no middle lobe. However, the term lingula is used to denote a projection of the upper lobe of the left lung that serves as the homologue. Some sources define the lingula 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.

Etymology

Lingula is Latin for "little tongue", giving the structure a common, humorous, nickname used in medical education: the "tongue in the lung".
