السؤال 79

A neuron must conduct an electrical impulse from the spinal cord to a distant muscle. Which adaptation is most directly suited to this long-range transmission?

  2. A large central vacuole
  3. A biconcave cell body
  4. A long conducting axonالإجابة الصحيحة

الشرح

A long axon provides a continuous route along which an electrical impulse can travel over a considerable distance. The cell body maintains the neuron, but its compact shape is not the main long-distance conducting adaptation.
