During swallowing, the contraction of the submental muscles directly pulls the anterior and vertical movement of the hyoid and larynx. ( Pearson Jr et al., 2012) This mechanism directly affects various functions of swallowing during the pharyngeal phase, especially aspiration, pharyngeal residue and upper oesophageal sphincter (UES) opening.. Throat pain that is persistent with no underlying reason can come from tension to the muscles of the neck.

Injury to the upper neck with pain and loss of mobility, even changes to. The main purpose of this paper was to review the role of the hyoid movement in the swallowing process and the effect of swallowing posture, age, gender, bolus properties on the hyoid movement. The displacement of the hyoid bone was divided into vertical and forward displacement. The vertical displacement of the hyoid bone contributes primarily to epiglottic and laryngeal closure, while the anterior displacement contributes primarily to opening of the UES. The infrahyoid muscles or strap muscles are a group of four paired muscles in the anterior neck below the hyoid bone, within the muscular triangle. They are responsible for depressing the hyoid during swallowing. These muscles can be remembered by the mnemonic "TOSS". Six points were plotted, the start of tongue tip movement; start of hyoid movement; start of rapid hyoid elevation identical to the onset of swallowing reex; hyoid bone reaching the most up forward posi- tion; onset of rapid hyoid descent; and return to resting position. The arrowhead indicates the endpoint of the movement. The sternohyoid muscle's leading operate is the melancholy of the hyoid bone. The hyoid bone is positioned lower than the mandible, or lower jaw, and is a 'U' fashioned bone that is partially responsible for tongue action and the movement of swallowing. The sternohyoid is one in all a pair of muscle tissue liable for this action.

The hyoid bone is a U-shaped bone that is held in place by the strap muscles of the anterior triangle of the neck. The bone has a central body (forming the center of the “U”) with two smaller protruding structures on the superior surface (lesser horns) and two larger bony protrusions from the body (greater horns) .. Of the various muscle groups involved in swallowing, the suprahyoid group of muscles play an important role in swallowing. This group includes the geniohyoid, mylohyoid, digastric, and stylohyoid, and is responsible for moving the hyoid bone, which then causes other physiological changes during swallowing.

The stylohyoid bone articulates with the petrous part of the temporal bone, allowing the stylohyoid bones to move cranial to caudal, in a pendulous manner. The ceratohyoid bone attaches to the distal end of the stylohyoid bone (by way of the epihyoid bone), and movement at this articulation lengthens the stylohyoid–ceratohyoid unit ( Fig. 3.1.14 )..

The hyoid is anchored by muscles from the anterior, posterior and inferior directions, and aids in tongue movement and swallowing. The hyoid bone provides attachment to the muscles of the floor of the mouth and the tongue above, the larynx below, and the epiglottis and pharynx behind. Structure and Functions of Hyoid Bone. In swallowing, it plays an important role in safely transporting the food bolus or liquid into the esophagus by rapidly moving the epiglottis to cut off the connection to the trachea, as if covering the trachea with a lid. This movement of the epiglottis is accomplished by moving the hyoid bone and the larynx in a coordinated manner.

The hyoid bone is small, and it functions as an attachment point for many muscles involved in swallowing, jaw movements, and respiration.. The first root word of sternohyoid is "sterno," this equates to the sternum while the last root word is "hyoid," which references the hyoid bone. The simplicity of the name of this muscle is that its name explains the regions that it originates from and to which it attaches.

Adequate hyoid bone movement during swallowing is important for effective bolus flow and pharyngeal clearing.

What muscle lifts the hyoid and larynx? The suprahyoid musculature includes the geniohyoid, mylohyoid, stylohyoid, hyoglossus, and the anterior belly of the digastric muscle. These muscles attach to the superior aspect of the hyoid bone, and their main combined function is to elevate the hyoid and larynx and move them superiorly and anteriorly. Hyoid bone and laryngeal movements in an anterior and superior direction serve to protect the respiratory tract during swallowing. Contraction of several muscles, such as the mylohyoid and geniohyoid, produce antero-superior hyoid bone movement, and when combined with activation of the thyrohyoid muscle, also elevate the larynx.
