5. The lips are muscular folds forming the anterior boundary of the oral cavity. A mucous
membrane covers the lips internally and the skin of the face coves them externally. The
vermillion border, which is the red part of the lips, is covered by keratinized epithelium that is
the transition between the epithelium of the mucous membrane and the facial skin. The
vermillion border can become chapped (dry and cracked), whereas the mucous membrane and
the facial skin do not. Propose as many reasons as you can to explain why the vermillion border
is more prone to drying than the mucous membrane or facial skin.
