Genioglossus Advancement in Sleep Apnea Surgery* The fibers retract the tip of the tongue, depress the dorsum of the tongue, and move the hyoid in an anterosuperior direction. The muscle receives the majority of its blood supply from the bilateral lingual arteries and is innervated by cranial nerve XII.
Considering this, what are the muscles of the tongue?
They are: the genioglossus, hyoglossus, styloglossus and the palatoglossus muscles. All the muscles of the tongue are innervated by the hypoglossal nerve (CN XII), except for the palatoglossus muscle which is supplied by the vagus nerve (CN X).
Secondly, what muscle retracts the tongue? The styloglossus originates at the styloid process and blends into the fibers of the inferior longitudinal tongue muscles and the hyoglossus, and elevates and retracts the tongue posteriorly and superiorly. The genioglossus, hyoglossus, and styloglossus are all innervated by the hypoglossal nerve (CN XII).
Similarly one may ask, what is tongue base retraction?
At the initiation of the pharyngeal phase, retraction of tongue base provides thrust to the bolus to propel it through the hypopharynx into the esophagus. Of these muscles, the hyoglossus and styloglossus are thought to be responsible for retracting the tongue base during swallowing (Fig. 1).
What organ is controlled by the Styloglossus muscle?
| Styloglossus | |
|---|---|
| Insertion | tip and sides of tongue |
| Artery | sublingual branch of the lingual artery. |
| Nerve | Hypoglossal nerve (CN XII) |
| Actions | retraction and elevation of tongue |
