Summary
| Description |
English: Correction: Salty taste is in fact in Type I cells which don't have a synapse! The diagram depicts the signal transduction pathway of the sour taste. Object A is a taste bud, object B is a taste receptor cell within object A, and object C is the neuron attached to object B. I. Part I is the reception of hydrogen ions or sodium ions. 1. If the taste is sour, H+ ions, from an acidic substances, pass through their specific ion channel. Some can go through the Na+ channels. If the taste is salty Na+, sodium, molecules pass through the Na+ channels. Depolarization takes place II. Part II is the transduction pathway of the relay molecules. 2. Cation, such as K+, channels are opened. III. Part III is the response of the cell. 3. An influx of Ca+ ions is activated. 4. The Ca+ activates neurotransmitters. 5. A signal is sent to the neuron attached to the taste bud. |
