The cheeks also create extensive food storage pouches in some species.

 

The cheeks (buccae) are important in the process of [[Mastication|mastication]] (and also drinking in herbivores). Minor [[Salivary Glands - Anatomy & Physiology|Salivary glands]] are located within the buccal musculature. The cheeks also create extensive food storage pouches in some species.

==Innervation==

==Innervation==

*Trigeminal nerve ([[Cranial Nerves - Anatomy & Physiology|CN V]])

The cheeks are innervated by the trigeminal nerve ([[Cranial Nerves - Anatomy & Physiology|CN V]]) and the facial nerve ([[Cranial Nerves - Anatomy & Physiology|CN VII]]).

*'Cheek pouches' are diverticula found in rodents (and monkeys) allowing food storage. The pouches can be extensive extending into the thorax with their own musculature.

*Papillae are present on the medial surface of the cheeks. These large, pointed and densely spaced projections of keratin provide protection to the underlying epithelium due to the rough diet.
