The palatal processes contribute to the formation of which structure?

• A. Hard palate
• B. Soft palate
• C. Nasal cavity floor
• D. Zygomatic arch

Answer: (A)

Palatal processes, or palatal shelves, grow from the maxillary prominences and move toward the midline, where they fuse with each other and with the primary palate and nasal septum to form the secondary palate. This fusion gives rise to the hard palate in its anterior portion, while the posterior part becomes the soft palate. Since their primary skeletal contribution is the hard palate, they contribute to its formation. The zygomatic arch comes from different facial bones, and although the nasal cavity is bordered by the palate, the best single outcome formed by these shelves is the hard palate.
