The lingual septum consists of a vertical layer of fibrous tissue, extending throughout the entire length of the median plane of the tongue, though not quite reaching the dorsum.

It is thicker behind than in front, and occasionally contains a small fibrocartilage, about 6 mm. in length.

It is well displayed by making a vertical section across the organ.
