The dorsal part of the lateralis nasi arises frona the alar cartilage of the nostril and ends in the medial wing of the nostril. The ventral part of the lateralis nasi consists of two layers which arise on the nasal process of the premaxilla and the lateral nasal cartilage and end in the lateral wing of the nostril. The orbicularis oculi is well developed. The corrugator supercilii is not present as a separate muscle, its place and function being taken by the frontalis. The malaris is broad, and spreads out below on the fascia over the buccinator and masseter; it is divided into two Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of
