Receptor molecules (or dendritic receptors) – signal receivers
Receptor molecules in the membrane of a neurone bind with the chemical that diffuses across the gap from the previous neurone. This chemical binding creates an electrical impulse.
The reception moll (receptor molecule) had a chemical reaction with a visitor from outside.
A receptor is a protein molecule that receives chemical signals from outside a cell. In neurones, they are embedded in the membrane at the end of a dendrite. They receive and bind with molecules released by synaptic vesicles in the axon terminal of another neuron. The binding of the two types of molecule produces an electrical charge which travels to the second neuron’s axon terminal, where the process is repeated.
