The prenasal cartilage (Fig. 70, pn) still points downwards, and by this time are formed the alinasal cartilages (Fig. 70, aln) developed from the trabecular horns, and the aliseptal cartilages which enclose the inferior turbinals (Fig. 70).

Such lateral developments of the ethmoid plate are the aliethmoid, aliseptal, and alinasal.
