Levator veli palatini muscle
- origin: it has two sites of origin:
- insertion: palatine aponeurosis between the two heads of palatopharyngeus muscle
- action: elevates and laterally deviates the soft palate. It also aids the tensor veli palatini muscle in opening the Eustachian tube on swallowing to allow pressure equalization of pressure between the middle ear and pharynx.
- innervation: pharyngeal plexus (from vagus nerve (CN X))
