Lecture Notes: Articulation Muscles

Introduction

• Lecture focused on articulation muscles, which are essential for speech production and other functions.
• Website reference provided: Quizlet, though access was restricted.

Key Muscles of Articulation

• Lips:

  • Orbicularis oris: muscle around the mouth responsible for closing lips.
  • Risorius: stretches the lips.

• Tongue:

  • Genioglossus: protrudes and depresses the tongue.
  • Styloglossus: retracts and elevates the tongue.

• Velum (Soft Palate):

  • Levator veli palatini: elevates the soft palate.
  • Tensor veli palatini: tenses the soft palate.

• Pharynx:

  • Superior, middle, and inferior pharyngeal constrictors: involved in swallowing.

Functions of Articulation Muscles

• Speech Production:

  • Articulation muscles coordinate to form sounds and words.
  • Importance of muscle control for clear speech.

• Swallowing:

  • Pharyngeal muscles play a key role in the swallowing process.

Common Disorders

• Dysarthria:

  • Disorder characterized by poor articulation.
  • Caused by neurological impairments affecting muscle control.

• Cleft Palate:

  • Congenital deformity that affects speech and swallowing.
  • Involves incomplete formation of the palate.

Conclusion

• Understanding articulation muscles is crucial for diagnosing and treating speech disorders.
• Further study recommended, though access to the recommended online resource was restricted.

Study Tips

• Review muscle functions and locations using diagrams.
• Practice pronunciation exercises to understand the role of different muscles.
• Engage in discussions or group studies to reinforce learning.
