Options
- AImpulse transmission across an electrical synapse is always slower than that across a chemical synapse
- BImpulse transmission across an electrical synapse is always faster than that across a chemical synapse
- CImpulse transmission across electrical and chemical synapses is the same
- DThere is no difference in impulse transmission between electrical and chemical synapses
Correct answer
B. Impulse transmission across an electrical synapse is always faster than that across a chemical synapse
Step-by-step solution
The action potential is generated in response to a stimulus and travels along the length of the axon, transmitting the nerve impulse. The rise in permeability to Na⁺ is short-lived and is followed by a rise in permeability to K⁺. K⁺ diffuses outside the membrane, restoring the resting potential of the membrane.A synapse is a junction between two neurons that allows the transmission of a nerve impulse from one neuron to another Electrical synapses are rare in our system. At electrical synapses, the membranes of pre- and post-synaptic neurons are in very close proximity, allowing for the flow of direct electrical current from one neuron into the other
