The effect of taste and mastication on lymph flow in the neck region

In 10 out of 12 patients, there was a significantly stimulatory effect on lymph flow during taste and in 9 out of 10 patients there was a significant stimulatory effect on lymph flow during mastication. The stimulatory effect of mastication could be a parallel to the conditions observed in the leg but the stimulatory effect of taste could also indicate an active process perhaps of neurogenic origin.
