Which extrinsic muscle elevates the larynx during swallowing?

The geniohyoid muscle plays a crucial role in elevating the larynx during swallowing. Located in the anterior neck, this muscle runs from the mandible to the hyoid bone. When it contracts, it pulls the hyoid bone upward and forward, which in turn elevates the larynx. This elevation is essential for the swallowing process, as it helps close the airway to prevent aspiration and directs the bolus into the esophagus.

Understanding the function of the geniohyoid within the context of swallowing is important in anatomy and physiology because it highlights its contribution to safe swallowing and airway protection. The elevation of the larynx is part of a coordinated series of muscle contractions that facilitate swallowing, ensuring that food is directed correctly and safely past the larynx.
