Myelinated axons are more efficient because repolarization requires ATP for the sodium pump. Reducing the amount of repolarization increases the efficiency of nerve impulse transmission.
تعتبر المحاور المغمدة بالميالين أكثر كفاءة لأن إعادة الاستقطاب تتطلب ATP لمضخة الصوديوم. تقليل إعادة الاستقطاب يزيد من كفاءة الانتقال العصبي.

|---|---|
| Back | myelinated more efficient as repolarisation requires ATP in Na+ pump, so reduced amount of repolarisation increases efficiency |
