Entoglossus

Entoglossus is a term used in anatomy to refer to the part of the hyoid apparatus that is located within the tongue. The entoglossus is a key component of the hyoid apparatus, which is a complex structure located in the throat that supports the tongue and assists in swallowing and vocalization.

Structure and Function

The entoglossus is a bony or cartilaginous structure that extends into the tongue from the basihyal, the most anterior bone of the hyoid apparatus. It provides support to the tongue and plays a crucial role in the movement of the tongue, particularly during the process of swallowing and vocalization.

In many animals, the entoglossus is a significant part of the hyoid apparatus. For example, in birds, the entoglossus is a long, slender bone that extends from the basihyal into the tongue, providing the tongue with support and mobility. In mammals, the entoglossus is typically less prominent, but still plays a crucial role in tongue movement and function.

Clinical Significance

Due to its location and function, the entoglossus can be affected by various medical conditions. For instance, trauma or disease affecting the hyoid apparatus can potentially impact the entoglossus, leading to difficulties with swallowing or vocalization. Additionally, certain surgical procedures involving the throat or tongue may require careful consideration of the entoglossus to avoid potential complications.
