Foramina of the maxilla

In addition, the lower maxilla has two foramina on each side; one (F in fig. 2) [foramen mandibulae] is seen in its inner region not far from the processes just mentioned, the other (G in fig. 1) [foramen mentale] on the outer surface near the root and the side of the lower lip. The inner one, which is both larger and uneven or rough, 15 provides a path for a portion of the nerve [n. mandibularis, n. alveolaris inferior] of the third pair of cerebral nerves [nervus trigeminus] that is distributed to the roots of the teeth (T in the 2nd fig. preceding ch. 2, Bk. 4), along with the small vein [vena alveolaris inferior] and the artery [arteria alveolaris inferior] which enter this foramen to nourish the teeth and lower maxilla. The outer foramen lets a branch of this nerve (V in the figure just mentioned and G in the 5th table of muscles) [nervus mentalis, rami labiales] pass from the maxilla into the lower lip, and it is much smaller than the one on the inside. If you insert a hair into the internal foramen [foramen mandibulae] of a dried jawbone, you will see it move 16 easily from this foramen to the outer one [foramen mentale], and if you break open the jawbone you will observe a continuous path carved like a canal [canalis mandibulae] from one foramen to the other.
