Intermaxillary segment

In a human embryo, the intermaxillary segment is a mass of tissue which forms from the merging of some of the tissues in the vicinity of the nose. It is primordial, meaning that in the further development of the embryo, this particular mass no longer appears, but parts of it remain in "the intermaxillary portion of the upper jaw, the prolabial portion of the upper lip, and the primary palate".

More precisely, 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]
