Lingual septum

Lingual septum
The mouth cavity. The cheeks have been slit transversely and the tongue pulled forward. (Lingual septum is visible at center of tongue, but not labeled.)
A pierced tongue, which has not accommodated for swelling
Latin	septum linguae
Gray's	subject #242 1132

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.
