Summary

summary

Oral motor structures are the parts of the mouth that work together to help with eating, speaking, and making facial expressions. This includes the lips, tongue, jaw, cheeks, and teeth. When these structures are strong and coordinated, kids can do things like chew food, talk clearly, and show emotions on their face.

Frequently Asked Question

How do oral motor structures affect eating?

Oral motor structures play a crucial role in chewing, manipulating food, and swallowing safely. Difficulties or delays in these structures can affect a child’s ability to eat certain foods or cause challenges in the chewing and swallowing process.

Can difficulties with oral motor structures affect speech?

Yes, oral motor structures are closely connected to speech production. If there are issues with these structures, it can impact a child’s ability to articulate sounds and form words properly, leading to speech difficulties.

Are there any signs that my child may have oral motor challenges?

Signs of oral motor challenges can include difficulty chewing, excessive drooling, food pocketing, limited food preferences, speech delays, and difficulty imitating or producing certain speech sounds. If you have concerns, it’s best to consult with a speech-language pathologist or pediatrician for an evaluation.

Scientific Definition

scientist

The term oral motor structures refers to the anatomical components and musculature of the oral cavity, including the lips, tongue, jaw, cheeks, palate, and teeth. Proper development and coordination of these structures is crucial for a variety of functions, such as feeding, speech production, and facial expressions. Weakness or incoordination of the oral motor structures can lead to difficulties with tasks like chewing, swallowing, articulating speech sounds, and conveying emotions through facial expressions.

Real World Example of Oral Motor Structures

Let’s look at how oral motor structures work together through the example of 5-year-old Liam:

  • Liam loves eating crunchy carrots, which requires his jaw to open and close, his teeth to bite and chew, his cheeks and tongue to move the food around, and his lips to keep the food in his mouth.
  • When talking with friends, Liam’s lips, tongue, and jaw work together to shape the sounds of words, while his cheeks and facial muscles help express his emotions.
  • Drinking from a straw engages Liam’s lips to seal around the straw, his cheeks to create suction, and his tongue to control the liquid flow.

Through activities like these, Liam’s oral motor structures develop strength and coordination every day, enabling him to eat, speak, and express himself effectively.

How Does Oral Motor Structures Work?

Oral motor structures work together to perform a variety of important functions:

  • Eating and drinking: Lips, cheeks, tongue, and jaw coordinate to bite, chew, and move food around the mouth for safe swallowing.
  • Speech production: Lips, tongue, jaw, and cheeks shape the mouth to articulate different speech sounds.
  • Facial expressions: Facial muscles around the mouth help convey emotions like happiness, sadness, or surprise.
