The buccal space is superficial to the buccinator muscle and deep to the platysma muscle and the skin.
The buccinator acts as a valve that prevents inflation of the duct during blowing.
In the head and neck, potential spaces are primarily defined by the complex attachment of muscles, especially mylohyoid, buccinator, masseter, medial pterygoid, superior constrictor and orbicularis oris.
The duct pierces the buccinator muscle, then opening up into the oral cavity on the inner surface of the cheek, usually opposite the maxillary second molar.
The lower lip is supported by the buccinator and chin muscles and rests on the lower teeth, making contact with the reed.
To the outer lip of the superior border, on either side, the buccinator is attached as far forward as the first molar tooth.
In particular, m. buccinator and linguae appear to be the most promising muscles for improving the sensitivity of artificial digestion and protecting consumers from this infection.
By keeping the food in the correct position when chewing, the buccinator assists the muscles of mastication.
