The stylopharyngeus muscle is not attached directly to the hyoid bone, however it acts indirectly to elevate both the hyoid bone and the larynx. Want a quick way to learn all the muscles of the head and neck, including those of the larynx? Our head and neck muscle anatomy chart is the...
The extrinsic and intrinsic muscles of thelarynxcontrol larynx position and function. The extrinsic muscles include the infrahyoid muscles that depress and thesuprahyoid musclesthat elevate the hyolaryngeal complex. The four infrahyoid muscles are the sternohyoid, omohyoid, sternothyroid, and thyrohyoid...
The intricate coordination of these muscles ensures that the larynx functions effectively during phonation and airway protection. Surgical interventions involving the laryngeal muscles and nerves require a detailed understanding of their anatomy and innervation to prevent complications such as voice changes and...

runs from styloid process of temporal bone to body of hyoid bone; innervated by facial nerve (CN VII)Function: elevate hyoid bone and move the larynx and pharynx, thus aiding deglutition and voice production (if mandible is fixed); depress the mandible and assist in opening of the mouth (...
exits the temporal fossa, passing underneath the zygomatic arch and inserting on the coronoid process of the mandible. The function of the anterior and mid fibers of the temporalis muscle is to elevate the mandible. The posterior fibers of the temporalis muscle function to retract the mandible....
