Dendrites receive information from other cells and transmit it to the cell body. Axons, on the other hand, conduct messages away from the cell body. The intercommunication junction between the axon terminal of one neuron and the dendrite of another neuron is called 'A'. The nerve impulse is transmitted across 'A' by a special chemical called 'B'.
What does 'B' stand for?
