The larynx and hyoid bone become drawn upward and forward by the weight of the organ.
From above downward one feels in the middle line the parts in the order previously mentioned, beginning with the hyoid bone.
It also controls, owing to the connections of the larynx with the hyoid bone, the muscles that fix the position of the larynx.
Their remnants become more or less important parts of the hyoid bone, and are solely employed in support of the tongue.
Above and from the sides rise two horns connected by bands to the hyoid bone from which the larynx is suspended.
The hyoid bone, serving as a medium of attachment for the tongue, may also be considered a portion of the larynx.
Swallowing is usually difficult and painful, especially in fracture of the hyoid bone.
The pharyngeal part, or base of the tongue, forms the anterior wall of the pharynx, and is attached to the hyoid bone.
