Body of tongue

Corpus linguae

Definition

Antoine Micheau & Muhammad A. Javaid

The body of tongue refers to the anterior two-thirds of the tongue that lies within the oral cavity proper. It is separated from the posterior one-third (or the root) of the tongue by means of a V-shaped groove called the sulcus terminalis.

The body of tongue is highly mobile and is covered by specialised mucosa containing numerous lingual papillae. Its superior (dorsal) surface bears the filiform, fungiform, and circumvallate papillae, while the inferior surface is smooth and covered by thin mucosa attached to the floor of the mouth by the lingual frenulum.

Structurally, the body of tongue consists of interlacing intrinsic muscles, which alter the shape of the tongue, and extrinsic muscles, which change its position.

Note:
