==Overview==

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.

==Structure and Function==

The cheeks are composed of many of the muscles of [[mastication]].

The main muscles of [[mastication]] are:
*The '''buccinator''' muscle
*The '''masseter''' muscle
*The '''lateral''' and '''medial''' pterygoids
*The '''digastricus''' muscle
*The '''zygomaticus''' muscle
*The '''temporalis''' muscle
*The '''platysma''' muscle


The '''[[Parotid Gland - Anatomy & Physiology|Parotid duct]]''' ends in a small papillae opposite the upper fourth premolar (canid).

==Innervation==

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

==Histology==

*Non keratinised stratified epithelium

*Some keratinisation in ruminants (see [[Cheeks#Species Differences|species difference section]] )

*[[Buccal Gland - Anatomy & Physiology|Buccal]] glands

*[[Zygomatic Gland - Anatomy & Physiology|Zygomatic]] salivary gland

==Species Differences==

===Rodents===
'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.

===Ruminants===
'''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.
