In a synapse, a chemical signal is transmitted from
(a) dendritic end of one neuron to the axonal end of another neuron
(b) axon to the cell body of the same neuron
(c) cell body to the axonal end of the same neuron
(d) axonal end of one neuron to the dendritic end of another neuron
Explanation:
Neurons communicate with one another at junctions called synapses. In a synapse, the electrical signal is converted into a chemical substance called a neurotransmitter by the presynaptic neuron. This chemical diffuses across the synaptic cleft and reaches the other neuron. The signal thus travels from the axonal end of one neuron to the dendritic end of another neuron. Hence, (d) is the correct option.
