Why is the flow of signals in a synapse from axonal end of one neuron to dendritic end of another neuron but not the reverse?
Step 1:
Step 2:
Step 3:
Step 4:
Step 5:
Answer variants:
The electrical impulse travels from the dendrite to the cell body and at the axon terminals.
The electrical impulse at the axon's end triggers the release of chemicals.
A similar synapse permits such impulses to be delivered from neurons to other cells like glands and muscle cells.
The information is received via chemical reaction at the dendritic tip of a nerve cell, which results in an electrical impulse.
The chemicals cross the synapse and initiate a similar electrical impulse in the following neuron's dendrite.
