Which infrahyoid muscles primarily assist in movements related to swallowing?

The infrahyoid muscles play a crucial role in the mechanics of swallowing. These muscles, located in the anterior region of the neck below the hyoid bone, are involved in the depression of the hyoid bone and the larynx, which is essential during the swallowing process. By stabilizing and lowering the hyoid, these muscles facilitate the passage of food from the mouth into the esophagus.

While "strap muscles" refers colloquially to the infrahyoid muscles due to their flat and strap-like appearance, the term may not comprehensively convey their specific function in swallowing. “Anterior neck muscles” is a broader category that may include additional muscles not primarily involved in swallowing. “Posterior cervical muscles” are located more towards the back of the neck and contribute to different functions, such as head movement and stabilization, rather than directly aiding in the process of swallowing.

Thus, the infrahyoid muscles are the most accurate and focused answer in this context, as they are specifically designed to assist with the movements associated with swallowing.
