Answer:
The muscle used to elevate the hyoid bone during swallowing is the Suprahyoid muscles.
Step-by-step explanation:
Suprahyoid muscles consists of digastric, stylohyoid, geniohyoid, and mylohyoid muscles. These four muscles are located above hyoid bone in neck.
The digastric muscles pull upward on hyoid bone on contracting. The mylohyoid elevates hyoid bone and tenses the mouth's floor. The Geniohyoid pulls hyoid bone anterosuperiorly results in the shortening floor of the mouth and widening pharynx during swallowing. The Stylohyoid elevates and retracts hyoid bone, elongating the mouth's floor.
The functions of all these muscles are different. In general, they assist in elevating the hyoid bone and widening the esophagus while swallowing.
