Which of the following is NOT a branch of the maxillary nerve?

• A. Posterior superior alveolar nerve
• B. Inferior alveolar nerve
• C. Pterygopalatine nerve
• D. Infraorbital nerve

Answer: (B)

The inferior alveolar nerve is not a branch of the maxillary nerve; rather, it is a branch of the mandibular nerve, which is the third division of the trigeminal nerve (CN V). The maxillary nerve, which is the second division of the trigeminal nerve, includes branches such as the posterior superior alveolar nerve, the pterygopalatine nerve, and the infraorbital nerve. The posterior superior alveolar nerve innervates the maxillary molars and surrounding structures, while the infraorbital nerve provides sensation to the anterior maxilla and the skin of the midface. The pterygopalatine nerve has branches that supply the nasal cavity, palate, and parts of the pharynx. Understanding the anatomical relationships and the origin of these nerves is crucial for effective local anesthesia administration in dental practice.
