Which nerve passes through the incisive foramen?

• A. Infraorbital Nerve
• B. Nasopalatine Nerve
• C. Mental Nerve
• D. Greater Palatine Nerve

Answer: (B)

The incisive foramen is the opening at the front part of the hard palate, where the incisive canal runs toward the nasal cavity. The nerve that passes through this canal is the nasopalatine nerve, a branch of the maxillary division of the trigeminal nerve. It provides sensory innervation to the mucosa of the anterior hard palate and the nasal septum, so it travels right through the incisive foramen to reach its target area. The other nerves have different pathways: the infraorbital nerve goes through the infraorbital canal and exits at the infraorbital foramen; the mental nerve exits the mental foramen; and the greater palatine nerve travels in the greater palatine canal and exits at the greater palatine foramen.
