The primary action of the levator veli palatini muscle is to elevate the soft palate, which is essential for proper swallowing and speaking. When this muscle contracts, it pulls the soft palate upwards and backwards, allowing it to close off the nasopharynx during swallowing. This action is crucial for preventing food and liquids from entering the nasal cavity, as well as facilitating the proper function of the vocal apparatus by providing a seal that enhances the resonance of the voice.

Understanding the role of the levator veli palatini is important in the context of both anatomy and clinical situations, such as in the assessment of velopharyngeal inadequacy, where improper elevation can lead to difficulties in swallowing and speech. In contrast, the other options pertain to actions that do not accurately reflect the function of this muscle.
