What is the difference in impulse transmission between electrical synapses and chemical synapses?

Options

  1. AImpulse transmission across an electrical synapse is always slower than that across a chemical synapse
  2. BImpulse transmission across an electrical synapse is always faster than that across a chemical synapse
  3. CImpulse transmission across electrical and chemical synapses is the same
  4. 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-
