Extrinsic laryngeal muscles are a group of muscles located outside the larynx that play a crucial role in its movement and function. These muscles help to elevate or depress the larynx during activities such as swallowing and speaking. They connect the larynx to surrounding structures, including the hyoid bone and sternum. These muscles can be categorized into two main groups: the suprahyoid muscles, which elevate the larynx, and the infrahyoid muscles, which lower it. Proper functioning of the extrinsic laryngeal muscles is essential for effective phonation and safe swallowing, as they help regulate the position of the larynx in the neck.
