What is lingula?

The lingula is a small, tongue-like projection found in various anatomical contexts. In the human body, it refers primarily to a part of the lung known as the lingula of the left lung, which is an extension of the upper lobe that resembles a tongue. Additionally, the term can also refer to a structure in the brain, specifically the lingula of the cerebellum, associated with motor control and coordination. Overall, the lingula serves as an important anatomical landmark in different systems.
