Which structure is NOT innervated by the Nasopalatine Nerve?

• A. Anterior part of canine teeth
• B. Palatal gingivae of upper incisors
• C. Hard palate of molars
• D. Upper incisors

Answer: (C)

The nasopalatine nerve primarily innervates the anterior region of the oral cavity, specifically targeting structures in the midline of the hard palate. This includes the palatal gingivae of the upper incisors and the mucosa of the anterior hard palate. It also provides sensory innervation to the upper incisors themselves. However, the hard palate of molars is innervated by other nerves, such as the greater palatine nerve, which serves the posterior parts of the palate. Therefore, the hard palate of molars is not a structure that receives innervation from the nasopalatine nerve, making this the correct choice. Understanding the specific areas each nerve supplies is essential in dental practice, particularly when considering anesthesia and surgical procedures.
