What is the effect of the myelin sheath on the conduction of neural impulses?
A)Myelin sheaths decrease the speed of electrical conduction.
B)Myelin sheaths increase the speed of electrical conduction.
C)Myelin sheaths vary the graded potential of the neuron.
D)Myelin sheaths are responsible for the refractory period after a neuron has fired.

Question

Quizplus · Accepted Answer

Myelin sheaths increase the speed of electrical conduction by allowing the electrical impulse to jump from one node of Ranvier to the next, a process known as saltatory conduction. This significantly speeds up the transmission of electrical signals along the neuron.
