| Research Abstract |
We studied the effects of voluntary swallowing by input from pheripheral sensory receptor. Each subject was instructed to swallow water or 0.3 M NaCl solution injected through a fine tube to the pharyngolaryngeal region voluntarily as fast as possible. The procedure was found to that voluntary swallowing is accelerated by tactile effect and deep mechanical effect of the pharyngolaryngeal region. The other hand, they can voluntary swallow when the pharyngolaryngeal region anesthetize. The wide variety of SI. This is inferred from the fact that the longer SI, the stronger accelerate effect of swallowing. We conclude that the peripheral sensory input fill the important role compensate for the difficult of swallowing elicit.
