Fig. 140. Head of human embryo of 7 weeks

Ventral aspect of upper jaw region. Lower jaw and tongue have been removed.

Wilhelm His (1831-1904).

A very important feature in the development of the maxilla is its agency in separating the nasal cavity from the mouth cavity. The palatine process of the bone grows medially and meets and fuses with its fellow of the opposite side in the medial line, the two processes together thus constituting about the anterior three-fourths of the bony part of the hard palate. It should be observed, however, that the palatine processes do not meet at their anterior borders, for the incisive bone is insinuated between them (see Figs. 140, 141).
