This is a real-world medical entrance exam question, please give the true answer based on the question and selection. Topic name: Misc., Subject name: Physiology
Saltatory Conduction is 
Select and explain. 
A. Action potential through myelin sheath, B. Action potential through nodes of Ranvier, C. Action potential through axon proper, D. Action potential through dentrites
B: Action potential through nodes of Ranvier
Answer: B: Action potential through nodes of Ranvier 
Explanation: (B) Action potential through nodes of Ranvier > Jumping of depolarisation from one node of Ranvier to the next in myelinated axons is called saltatory conduction.> It is rapid process and myelinated axons conduct up to 50 times faster than the fastest unmyelinated fibres.
