They may also be referred to as jowls . " Buccal " means relating to the cheek. In humans, the region is innervated by the buccal nerve . The area between the inside of the cheek and the teeth and gums is called the buccal pouch or buccal cavity and forms part of the mouth .

Some animals such as squirrel s and hamster s use the buccal pouch to carry food or other items.
In vertebrate s, markings on the cheek area ( malar stripes/spots/... ), particularly immediately beneath the eye, often serve as important distinguishing features between species or individual s.
The inside of the cheek is lined with a mucous membrane (buccal mucosa, part of the oral mucosa ). It is the most common location from which a DNA sample can be taken (during a cheek cotton swab|swab ).
The cheeks are covered externally by hairy skin, and internally by stratified squamous epithelium. This is mostly smooth, but may have aborally directed papillae (e.g.: ruminant s). The mucosa is supplied with secretions from the Buccal glands, which are arranged in superior and inferior groups. In carnivores, the superior buccal gland is large and discrete: the Zygomatic gland. During mastication (chewing), the cheeks and tongue between them serve to keep the food between the teeth.
