Lateral nasal prominence
Diagram showing the regions of the adult face and neck related to the fronto-nasal process and the branchial arches.
Gray's	subject #13 67
Precursor	frontonasal prominence

By the upgrowth of the surrounding parts the olfactory areas are converted into pits, the olfactory pits, which indent the fronto-nasal process and divide it into a medial and two lateral nasal prominences (or lateral nasal processes, or nasolateral, or nasal prominences^[1] )
