The styloglossus muscle is a bilaterally paired muscle of the tongue. It originates at the styloid process of the temporal bone . It inserts onto the side of the tongue.
The pharyngeal muscles are a group of muscles that form the pharynx, which is posterior to the oral cavity, determining the shape of its lumen, and affecting its sound properties as the primary resonating cavity.
The inferior longitudinal muscle lines the sides of the tongue, and is joined to the styloglossus muscle. It functions to shorten and curl the tongue downward. The vertical muscle is located in the middle of the tongue, and joins the superior and inferior longitudinal muscles. It functions to flatten the tongue.
CN XII is a nerve with a sole motor function. The nerve arises from the hypoglossal nucleus in the medulla [ 1 ] [ 2 ] as a number of small rootlets, pass through the hypoglossal canal and down through the neck, and eventually passes up again over the tongue muscles it supplies into the tongue.
The stylopharyngeus is a long, slender, [1] [2] tapered pharyngeal muscle. [2] It is cylindrical superiorly, and flattened inferiorly. [1]It passes inferior-ward along the side of the pharynx [1] between the superior pharyngeal constrictor (situated deep to the stylopharyngeus) and the middle pharyngeal constrictor (situated superficial to the stylopharyngeus), [2] before spreads out beneath ...
The temporal styloid process is a slender bony process of the temporal bone extending downward and forward from the undersurface of the temporal bone [1] just below the ear. [citation needed] The styloid process gives attachments to several muscles, and ligaments.
