Taste transduction通路
WebDepending on the region in which each taste bud is located, there are primarily three different nerves that the taste cells synapse with to carry the message to the brain. First of all, the chorda tympani (VI) is the nerve that conducts signals from taste buds located in the front of the tongue and on the sides of the tongue. WebNov 25, 2024 · Like olfaction, the sense of taste allows the detection and discrimination of chemicals in the environment. However, while olfaction is specialized in the detection of volatile chemicals, taste is restricted to the detection of contact-chemicals. Two families of mammalian taste receptors, T1R and T2R, involved in recognition of sweet, umami (the …
