Which branches are included under the maxillary nerve?

The maxillary nerve, which is one of the three major branches of the trigeminal nerve (cranial nerve V), specifically encompasses several important branches. The infraorbital nerve is a significant branch that supplies sensation to areas such as the upper lip, cheek, and lower eyelid. The pterygopalatine nerve branches off and innervates various structures including the palatine glands and nasal cavity. The zygomatic nerve, another branch, conveys sensory information from the zygomatic bone region, contributing to sensation in the lateral aspect of the face.

This configuration underlines the maxillary nerve's role in sensation for the mid-facial region, and its branches are crucial for dental procedures involving the upper jaw. Understanding these branches is essential for dental professionals as it aids in effective anesthesia delivery and diagnosing facial pain related to nerve issues.
