What does the styloglossus muscle do?

Action. The styloglossus draws up the sides of the tongue to create a trough for swallowing. As a pair they also aid in retracting the tongue.

What does the Palatoglossus muscle do?

Structure and Function The palatoglossus muscle functions to elevate the posterior portion of the tongue. It also draws the soft palate inferiorly, thereby narrowing the diameter of the oropharyngeal isthmus.

What nerve Innervates the styloglossus?

The styloglossus muscle draws up the sides of the tongue to create a trough for swallowing following adequate mastication. The pair of styloglossus muscles work together on each side to retract the tongue. The styloglossus muscle is innervated by the hypoglossal nerve (CN XII).

Where is the styloglossus located?

tongue
The styloglossus muscle originates at the distal lateral aspect of the stylohyoid bone and travels the length of the tongue, along its lateral aspect (Sisson 1975a). Near the tip of the tongue the paired muscle meets and ramifies with fibers of other tongue muscles.

Can Mylohyoid cause pain?

Due to the position of the submandibular gland a referred pain at the mylohyoid muscle could be present.

What are styloglossus and stylohyoid?

The origin of the stylohyoid muscle is from the middle of the posterior surface of the styloid process of the temporal bone near its base. The styloglossus muscle lies medially and anterior to the stylohyoid muscle. The stylopharyngeal muscle is located between the stylohyoid and the styloglossus muscle.

Why Palatoglossus is supplied by vagus?

The vagus nerve, which is also known as the 10th cranial nerve (CN X), is the nerve that supplies the palatoglossus muscle with electrical impulses from the brain. Once this muscle receives electrical impulses from the brain, it will contract, pulling the back of the tongue upward and the soft palate downward.

What is the function of Glossopalatine Arch?

The palatoglossal arch is located anteriorly. It contains the palatoglossus muscle and connects the soft palate with the root of the tongue. The palatopharyngeal arch is found posteriorly and it contains the palatopharyngeus muscle. It joins the soft palate with the wall of the pharynx.

What is the origin of the Styloglossus muscle?

The styloglossus muscle is an extrinsic muscle of the tongue, and its origin in the styloid process of the temporal bone is well documented. However, some authors have noted variations in its origin.

What bone does the styloglossus attach to?

The styloid process is a cylindrical, slender, needle-like projection of varying lengths averaging 2 to 3 cm. The styloid process projects from the inferior part of the petrous temporal bone and offers attachment to the stylohyoid ligament and the stylohyoid, stylopharyngeus, and styloglossus muscles.

What type of muscle is the styloglossus?

extrinsic muscle
The styloglossus muscle is an extrinsic muscle of the tongue, and its origin in the styloid process of the temporal bone is well documented.
