In neuroscience, nerve conduction velocity (CV) is an important aspect of nerve conduction studies. It is the speed at which an electrochemical impulse propagates down a neural pathway. Conduction velocities are affected by a wide array of factors, which include; age, sex, and various medical conditions. Studies allow for better diagnoses of various neuropathies, especially demyelinating diseases as these conditions result in reduced or non-existent conduction velocities.

  • تشكل سرعة توصيل العصب (سي في) إحدى الجوانب المهمة في دراسات توصيل العصب. وتُعرَّف بسرعة انتشار الدفعات الكيميائية الكهربائية على طول المسار العصبي. تتأثر سرعات التوصيل بمجموعة متنوعة من العوامل، بما في ذلك العمر والجنس والحالات الطبية المختلفة. تسمح الدراسات بتحسين القدرة على تشخيص الاعتلالات العصبية، على وجه الخصوص الأمراض المزيلة للميالين إذ تنتج هذه الحالات عن انخفاض سرعات التوصيل أو انعدامها.

  • La velocità di conduzione dell'impulso nervoso è la velocità alla quale un impulso si propaga in un neurone e si misura in m/s (metri al secondo). La velocità di conduzione dell'impulso nervoso è influenzata da una vasta gamma di fattori, tra cui età, sesso e varie condizioni mediche. In generale può variare da meno di 5 metri al secondo a 120 metri al secondo in relazione al diametro della fibra, se più spessa il passaggio può essere più veloce, e alla guaina mielinica, che ricoprendo l'assone consente una velocità di conduzione più elevata.

  • Die Nervenleitgeschwindigkeit, abgekürzt NLG, gibt an, wie schnell ein elektrischer Impuls entlang von Nervenfasern weitergeleitet wird. Dazu wird – wie in der Physik definiert – der Quotient aus der Ortsdifferenz und der Zeitdifferenz gebildet. Erstmals gemessen wurde die Nervenleitgeschwindkeit von Hermann Helmholtz. (de)
