Deglutition | Muscles of the Palate [OINAs]

The video tutorial provides an in-depth look at the anatomy and function of the pharyngeal constrictors, oral and nasal cavities, and the swallowing mechanism. It explains the roles of various muscles, including those of the soft palate, tongue, and uvula, in facilitating swallowing and preventing food from entering the nasal cavity or trachea. The tutorial also covers the innervation and blood supply of these muscles, highlighting the importance of the vagus nerve and other cranial nerves.
