Depression of mandible is achieved by_______________?
Correct answer: A. All of the above
- A. All of the above
- B. Lateral pterygoid
- C. Geniohyoid
- D. Digastric
Explanation
Mandibular depression is assisted by the digastric and geniohyoid muscles when the hyoid is stabilized, while the lateral pterygoid pulls the condyle and disc forward. Since all three can contribute to opening the mouth, the combined option is appropriate.
