Primary palate
Gray49.png
Primitive palate of a human embryo of thirty-seven to thirty-eight days.
Latin palatum primarium; processus palatinus medianus
Gray's p.70
Precursor intermaxillary segment
Code TE E5.4.1.1.4.0.3

Around the fifth week, the intermaxillary segment araises as a result of fusion of the two medial nasal processes and the frontonasal process within the embryo. The intermaxillary segment give rise to the primary palate. The primary palate will form the premaxillary portion of the maxilla (anterior one-third of the final palate). This small portion is anterior to the incisive foramen and will contain the maxillary incisors.
