Barber Practice State Board Practice Exam

Which of the following branches of the fifth cranial nerve is affected by massage?

1. Maxillary nerve

2. Mandibular nerve

3. Infraorbital nerve

4. Buccal nerve

The correct answer is: Infraorbital nerve

The correct choice reflects the role of the infraorbital nerve, a branch of the maxillary division of the fifth cranial nerve, in facial sensation and its relationship to massage techniques commonly used in barbering. The infraorbital nerve supplies sensation to the area under the eye, upper lip, and part of the cheek. When performing facial massages or skin treatments, barbers often work on regions innervated by this nerve, which makes it particularly relevant in terms of affecting sensation and promoting relaxation in those areas. Understanding the facial anatomy and the distribution of the cranial nerves is crucial in barbering, as it enhances the effectiveness of massage techniques. While other branches like the maxillary and mandibular nerves also play roles in facial sensation, the infraorbital nerve specifically corresponds to the regions typically massaged during barber services, emphasizing the importance of knowing the paths and effects of these nerves in practical applications.
