The characteristic upward movement of a thyroglossal duct cyst on tongue protrusion is primarily due to its anatomical relationship with which of the following structures?

Explanation

The thyroglossal duct, from which the cyst originates, typically passes through or is intimately associated with the hyoid bone. When the tongue is protruded, the suprahyoid muscles contract, elevating the hyoid bone. Because the thyroglossal duct (and thus the cyst) is connected to the hyoid bone, the cyst is pulled upwards along with the hyoid bone, demonstrating the characteristic movement.
