What is the stylopharyngeus?
The stylopharyngeus muscle is a long, slender and tapered longitudinal pharyngeal muscle that runs between the styloid process of the temporal bone and the pharynx and functions during the pharyngeal phase of swallowing.
What is between the Palatoglossus and Palatopharyngeus?
The anterior pillar is the palatoglossal arch formed of the palatoglossus muscle. The posterior pillar is the palatopharyngeal arch formed of the palatopharyngeus muscle. Between these two arches on the lateral walls of the oropharynx is the tonsillar fossa which is the location of the palatine tonsil.
What is hyoid bone for?
Together with its attached muscles, the hyoid bone has two important functions: it holds up the tongue, which sits above it, and it holds up the larynx, which hangs below it. It also transmits the force of muscles that help to open the jaw. Let’s take a closer look at the hyoid bone.
Why is palatoglossus innervated 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 Passavants Ridge?
The Passavant cushion or ridge is a small prominence in the posterior pharynx, formed from a focal bulge of the superior pharyngeal constrictor muscles during swallowing.
What is the insertion of the palatoglossus?
Palatoglossus arises from the palatine aponeurosis of the soft palate, where it is continuous with the muscle of the opposite side, and passing downward, forward, and lateralward in front of the palatine tonsil, is inserted into the side of the tongue, some of its fibers spreading over the dorsum, and others passing …
Is the hyoid bone lump?
Solid primary tumors of the hyoid bone are exceedingly rare. Reported cases have included chondrosarcoma, plasmacytoma, osteosarcoma, giant cell tumor, aneurysmal bone cyst, and benign osteoma. Patients with hyoid bone tumors usually present with dysphagia and may have a palpable neck mass.
Do females have a hyoid bone?
A total of 100 hyoid bones, 66 males and 34 females, in different age groups were studied. According to the study, hyoid bones were highly polymorphic in shape across the ages in both sexes. In adult males, V shape is more common (36.16 %) when compared to U shaped hyoid bone (35.29%) in adult females.
What happens if hypoglossal nerve is damaged?
The hypoglossal nerve can be damaged at the hypoglossal nucleus (nuclear), above the hypoglossal nucleus (supranuclear), or interrupted at the motor axons (infranuclear). Such damage causes paralysis, fasciculations (as noted by a scalloped appearance of the tongue), and eventual atrophy of the tongue muscles.
Is it normal to have a lump in the palatoglossal arch?

What is the palatoglossus muscle?
The palatoglossus muscle, also known as musculus palatoglossus, is among the four extrinsic muscles of the tongue and the paired muscles of the soft palate. The right and left palatoglossus muscles create ridges in the lateral pharyngeal wall, referred to as the palatoglossal arches (anterior faucial pillars).
What are the white spots on my eyelid after blepharoplasty?
Some persons who had surgery on their upper or lower eyelid referred to as blepharoplasty may develop small, white colored spots or bumps on the eyelid. This growth may occur months or even a year post surgery. The small, white bumps usually form on the incision lines. The bump interferes with your vision.
