Classroom Note:
The Roles of the Tongue and Lip in Feeding
Roles of the Tongue in Feeding:
- Tasting Food: The tongue contains taste buds that help in detecting sweet, sour, salty, and bitter flavors.
- Manipulating Food: It helps in moving food around the mouth for effective chewing.
- Forming Bolus: The tongue shapes chewed food into a bolus (a small rounded mass of chewed food) before swallowing.
- Swallowing: It plays a crucial role in the process of swallowing by pushing the bolus towards the back of the mouth and into the esophagus.
Roles of the Lips in Feeding:
- Holding Food: Lips help to keep food inside the mouth while eating.
- Sensing Temperature: Lips are sensitive to temperature, which helps in gauging the temperature of food before it enters the mouth.
- Aiding Sucking: In the case of liquids, the lips enable sucking by creating a seal around a straw or the opening of a cup.
- Speech: While not directly involved in the process of feeding, the lips play a vital role in articulating sounds during speech, which is often associated with eating situations and social interactions around food.
Evaluation:
- What are the roles of the tongue in feeding?
- How do the lips assist in the feeding process?
- Why is oral care important?
