Document Summary
The hard palate is formed by facial bones (what bones are involved?). The soft palate is muscular and helps to prevent food from going upwards into the nasopharynx during swallowing. The paired palatine tonsils are found in the area called the fauces between the oral cavity and oropharynx. The lingual tonsil is located at the base of the tongue. The tongue keeps food between the teeth during mastication and forms a ball called a bolus to make swallowing easier. It also plays an important role in speech. Intrinsic muscle change tongue shape while extrinsic muscle change tongue position. (what nerve controls these muscles?) The lingual frenulum attaches the tongue to the inferior part of the oral cavity. The lingual tonsil sits at base of tongue and protects against invasion by bacteria. Taste buds respond to substances dissolved in saliva. You"ve already reviewed the nerves that carry sensations from the oral cavity.
