Document Summary

Then the mandible, lips, velum/soft palate, cheeks, pharynx (also the hyoid and the larynx) Most important articulators tongue, mandible, teeth, hard palate, velum. Bounded by lips (front), cheeks (sides), palate (roof), tongue (moveable floor), pharynx (back) Velum is a muscular extension of the hard palate. The uvula marks the end of the velum. Anterior/posterior faucial pillars tissue on either side of the velum, posterior margin of the oral cavity. Space between posterior teeth and cheeks (lateral margin) Posterior boundary pharyngeal protuberance of the occipital bone. Lateral wall contains the orifice of the eustachian tube. Composed of maxillae, palatine bones, and nasal bones. Lingual (tongue) contacts articulators in various locations. Velopharyngeal velum touches posterior pharyngeal wall. Laryngeal (vocal folds) open or closed position. Movement of lips achieved by these muscles. Tongue and velum have their own musculatures separate from these muscles. Made of muscle, mucous membrane, glandular tissues, and fat covered in epithelium.
