Gustatory nerve fibers

WebJan 16, 2024 · However, the majority of gustatory studies examine the anterior two-thirds of the tongue, supplied by the chorda tympani branch of the facial nerve (VII). Studies have also suggested that somatosensory trigeminal fibers anastomose with facial taste fibers peripherally, acting in concordance. This further blurs the lines of the gustatory pathway. WebIn addition to taste signals, these nerves also carry temperature and tactile information from their receptive fields. Taste fibers in these nerves tend to be A fibers with conduction velocities of 2-18 m/sec. There may be pathways for taste fibers other than the three nerves previously mentioned, but this is debatable (sometimes hotly).
