An anatomical term (from the Latin bucca for cheek) that means relating to the mouth or cheek. The buccal cavity (oral cavity) extends from the vermilion (red) border of the lips to the junction of the hard and soft palates in the roof of the mouth, and to the circumvallate papillae on the tongue. The buccal cavity consists of the lips, commissures, all surfaces (anterior 2/3 or oral, dorsal, ventral, border) of the tongue except the base of tongue, lingual tonsil, gums (alveolar ridge), floor of mouth, hard palate, buccal mucosa, and retromolar trigone.
