[Campbell Biology P.1132] How would severing an axon affect the flow of information within a ... | Practice Question

How would severing an axon affect the flow of information within a neuron and its ability to communicate with other cells?

  • A: Information flow from dendrites to the cell body would cease.
  • B: The neuron would no longer be able to receive any signals.
  • C: Transmission of signals from the cell body to other neurons or effector cells would be prevented.
  • D: Only the resting potential of the neuron would be affected.

Explanation

The axon is the long projection that extends from the neuron's cell body and is specialized for transmitting electrical signals action potentials away from the cell body to other neurons or effector cells at the synapse. Severing an axon would directly interrupt this transmission pathway, preventing the neuron from sending output signals.
