Question
Conduction of impulses via saltatory mode in myelinated neurons is _____ than unmyelinated neurons .
Answer: Option C
:
C
Conduction of impulses in myelinated neurons is faster than unmyelinated neurons. This is because myelin forcesthe action potential to jump from one node of Ranvier to the next. Na+ channels accumulate in the nodes of Ranvier In large myelinated axons, the conduction can be as much as 100 m/sec, or 220 miles per hour.The propagation speed is slower in small, unmyelinated fibers.
