What is a pick? What is its role in the transmission of nerve impulses?
| October 27, 2020 | Education
A mediator is a biologically active substance that is released from the endings of an axon under the action of nerve impulses; it mediates between cells in a typical chemical synapse (synapse is the place of contact of a neuron with another cell). The mediator comes into contact with receptors sensitive to it, located on the membrane of a neighboring cell. Depending on the chemical nature of the mediator, it either forms nerve impulses, or for some time goes into a state of inhibition.
