Lingula

Lingula is a part of the anatomy of the lung, specifically a part of the left lung. It is a small, tongue-like projection that comes off the inferior lobe of the lung. The lingula is the equivalent to the middle lobe of the right lung, and it is named for its resemblance to a small tongue (lingula is Latin for "little tongue").

Anatomy

The lingula is located on the mediastinal surface of the lung, which is the side of the lung that faces towards the middle of the chest, and it is protected by the heart and the pericardium. It is made up of two bronchopulmonary segments, the superior and the inferior lingular segments.

Clinical significance

Due to its location, the lingula is often involved in pneumonia that affects the lower lobes of the lungs. It can also be affected by lung cancer, and in some cases, it may need to be removed in a procedure known as a lingulectomy.
