The suprahyoid muscles are a group of four muscles located above the hyoid bone in the neck. These muscles include the digastric, mylohyoid, stylohyoid, and geniohyoid. They play a crucial role in various functions, such as swallowing and speaking, by helping to elevate the hyoid bone and the larynx during these activities. These muscles are innervated by different cranial nerves, including the trigeminal nerve and the facial nerve. Their coordinated action is essential for proper movement of the jaw and throat, contributing to the overall mechanics of the oral cavity and pharynx.
