Milady Esthetics State Board Practice Test

Which part of the body does the infraorbital nerve affect?

1. Forehead and temples

2. Lower eyelid and side of the nose

3. Cheeks and chin

4. Nose and upper lip

The correct answer is: Lower eyelid and side of the nose

The infraorbital nerve is a crucial sensory nerve that is a continuation of the maxillary division of the trigeminal nerve (cranial nerve V). It primarily innervates the lower eyelid and the side of the nose, making option B the correct answer. This nerve plays a significant role in providing sensation to the facial area beneath the orbit, affecting both the skin and the underlying tissues. Understanding the area impacted by the infraorbital nerve is essential for various esthetic procedures, including injections or therapies aimed at relieving pain or enhancing facial aesthetics. Mapping out the regions innervated by this nerve helps practitioners avoid any complications during treatments. The other options refer to areas innervated by different branches of the trigeminal nerve, not specifically by the infraorbital nerve.
