Question 3
In a synapse, 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 the axonal end of the same neuron
(d) axonal end of one neuron to dendritic end of another neuron
(d) axonal end of one neuron to dendritic end of another neuron
The gap between the axonal end of one neuron and the dendrite of another neuron is called a synapse. There are two types of synapses - electrical synapse and chemical synapse. In an electrical synapse, electrical impulse jumps across the synapse. However, in a chemical synapse, the electrical impulse sets off the release of some chemicals from the axonal end. These chemicals cross the synapse and start a similar electrical impulse in the dendrite of the next neuron.
