| 🔍 Nasopharyngeal Muscles |
| Add the palatopharyngeus muscle. |
| Add the stylopharyngeus muscle. |
| Add the salpingopharyngeus muscle. |
| Add the palatoglossus muscle. |
What is the function of these muscles? |
|
|
The palatopharyngeus, salpingopharyngeus and stylopharyngeus elevate the soft palate and effectively close the nasopharynx. The palatoglossus elevates the back of the tongue. All but the stylopharyngeus are innervated by CN X. The stylopharyngeus is innervated by CN IX. |
