Abstract:
In the present work the importance of the cricopharyngeal muscle as the main constituent of the pharyngoesophageal sphincter is showed. Some aspects traditionally admitted by the classic anatomic descriptions and some hypothesis about the function of this part of the aerodigestive pathway are discussed.
