The styloglossus muscle is a bilaterally paired muscle ... It passes anterioinferiorly from its origin to its insertion between the internal carotid artery and the ...
The superior longitudinal muscle runs along the upper surface of the tongue under the mucous membrane, and functions to shorten and curl the tongue upward. It originates near the epiglottis, at the hyoid bone, from the median fibrous septum. The inferior longitudinal muscle lines the sides of the tongue, and is joined to the styloglossus muscle.

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 hypoglossal nerve provides motor control of the extrinsic muscles of the tongue: genioglossus, hyoglossus, styloglossus, and the intrinsic muscles of the tongue. [2] These represent all muscles of the tongue except the palatoglossus muscle, which is innervated by the vagus nerve. [2] The hypoglossal nerve is of a general somatic efferent ...
These four muscles have different actions, but in general assist in elevating the hyoid bone and widening the esophagus during swallowing.When the two bellies of the digastric contract, they pull upward on the hyoid bone; but if the hyoid is fixed from below, the digastric assists in extreme opening of the mouth such as yawning or taking a large bite of an apple.

The styloid process gives attachments to several muscles, and ligaments. [1] It serves as an anchor point for several muscles associated with the tongue and larynx.

The pharyngeal muscles (involuntary skeletal) push food into the esophagus. There are two muscular layers of the pharynx: the outer circular layer and the inner longitudinal layer. The outer circular layer includes: Superior constrictor muscle; Middle constrictor muscle; Inferior constrictor muscle
