Which one of the following ion pairs is involved in nerve impulses?
EASY
Life Science>Relationship>Interaction>Neuronal Decision Making Process
Each neuron has a cell body, axon, and dendrites. The dendrites are the protoplasmic extensions of the nerve cell. The axodendritic type of chemical synapse is formed by the association between the axon terminal of the pre-synaptic neuron and the dendrites of a post-synaptic neuron. The action potential causes the fusion of the synaptic vesicle to release the neurotransmitters for neurotransmission. Select the correct option from the following.
