What is the buccinator mechanism?
Buccinator along with orbicularis oris and pharyngeal constrictor forms a functional unit (buccinator mechanism) which is essential for orofacial functions (swallowing, sucking, whistling, chewing, vowel pronunciation). Also, the longitudinal fibers hold the bolus of food between the teeth during mastication.
What is the buccinator muscle used for?
The buccinator compresses the cheeks against the teeth and is used in acts such as blowing. It is an assistant muscle of mastication (chewing) and in neonates it is used to suckle.
How does the buccinator muscle play a role in mastication?
The buccinator muscle forms the lateral wall of the oral cavity. It is presumed to aid mastication by maintaining bolus position. Such a function would involve thickening the cheek, possibly compressing the alveolar bone and contributing to malocclusions.

What is superficial to the buccinator?
Superficial to buccinator is the buccal fat pad. Deep to the muscle is the mucous membrane of the cheek. It is not a primary muscle of mastication – it does not move the jaw – and this is reflected in its motor innervation from the facial nerve.

Which are attachments of the orbicularis oris?
The fibres of the orbicularis oris enclose the opening to the oral cavity. Attachments: Arises from the maxilla and from the other muscles of the cheek. It inserts into the skin and mucous membranes of the lips.
