Question

Quizplus · Accepted Answer

The frontal belly of the epicranius muscle is responsible for raising the eyebrow. Damage or paralysis of this muscle can result in the inability to raise the eyebrow. The mastoid process and temporalis muscle are not directly involved in eyebrow movement, while the orbicularis oculi muscle is responsible for closing the eyelids.
