Intermaxillary segment
Diagram showing the regions of the adult face and neck related to the fronto-nasal process and the branchial arches. (Globular processes labeled at center right.)
Gray's	subject #13 68
Precursor	medial nasal prominence[1]
Gives rise to	primary palate[2]

The rounded lateral angles of the medial process constitute the globular processes. It is also known as the intermaxillary segment^[3] It gives rise to the premaxilla.^[4]
