In a synapse, a chemical signal is transmitted from
(a) dendritic end of one neuron to axonal end of another neuron
(b) axon to the cell body of the same neuron
(c) cell body to axonal end of the same neuron
(d) axonal end of one neuron to dendritic end of another neuron

Answer : (d) axonal end of one neuron to dendritic end of another neuron.

Explanation:

A synaptic gap composed of SYNAPSE allows an electric impulse to pass from the axon to the dendrite of one neuron to the other.
