1) During swallowing, the lumen of the eustachian tube opens, and the toms tubarius elevates as a result of the combined action of three muscles: the tensor veil palatini, the levator veli
palatini, and the superior constrictor.
They originate on the floor near the pharyngeal ostium and expand between the tensor and levator veli
In studying the velopharyngeal mechanism, the paired levator veli palatini muscles are generally considered the primary muscles of closure during speech (Kahane, 1986); however, this is an over simplification.
Muscle spindles in the human levator veli palatini and palatoglossus muscles.
Oral air pressure and nasal airflow rate on levator veli palatini muscle activity in patients wearing a speech appliance.
Effect of placement of a speech appliance on levator veli palatini muscle activity during speech.
MRI showed (1) prominence of the left side of the tongue base in the oropharynx, best appreciated on T1-weighted images; (2) asymmetric T2 hyperintensity; (3) mild, diffuse enhancement of the left half of the tongue; and (4) atrophy of the left levator veli
palatini and tensor veli palatine muscles.
