Question

Quizplus · Accepted Answer

The inferior alveolar nerve block involves administering local anesthesia in the area around the mandibular molars. However, if the facial nerve is affected during the procedure, it can result in temporary paralysis of the muscles responsible for eyelid closure, known as Bell's palsy. This is because the facial nerve innervates the muscles responsible for facial expression, including the orbicularis oculi muscle, which is responsible for eyelid closure. Therefore, option B, motor function of the facial nerve, is the correct choice.
