Primary palate

The primary palate is an embryonic structure in the developing skull that, together with the more posterior secondary palate, separates the nasal from the oral cavity.^[1] It is a derivative of the first pharyngeal arch.^[2] Around the fifth week, the intermaxillary segment arises as a result of fusion of the two medial nasal processes and the frontonasal process within the embryo.^{[citation needed]} The intermaxillary segment gives rise to the primary palate. The primary palate will form the premaxillary portion of the maxilla (anterior one-third of the final palate).^{[citation needed]} This small portion is anterior to the incisive foramen and will contain the maxillary incisors.^[3]
