How does impulse transmission occur across electrical synapses?
Options
- ABy the release of neurotransmitters
- BBy the flow of direct electrical current
- CBy the transmission of magnetic fields
- DBy the transmission of electrical impulses along a single axon
Correct answer
B. By the flow of direct electrical current
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 anotherNeurotransmitters are chemicals involved in transmitting impulses at chemical synapses.
