Why is myelin important in the nervous system? 
A. It allows signals to travel faster along axons because depolarization occurs only at myelinated 
locations. 
B. It allows signals to travel faster along axons because depolarization occurs only at nonmyelinated 
locations. 
C. It bundles the dendrites of adjacent neurons together. 
D. It increases capacitance across the cell membrane, which helps electrical signals to leave the axons. 
E. It traps neurotransmitters, increasing their concentratio...

Excitability - Answer- the ability of non-pacemaker heart cells to respond to an electrical impulse that begins in pacemaker cells. Depolarization - Answer- occurs when the normally negatively charged cells within the heart muscle develop a positive charge. Conductivity - Answer- the ability to send an electrical stimulus from cell membrane to cell membrane. As a result, excitable cells depolarize in rapid succession from cell to cell until all cells have depolarized. Ex: the wave of depolarizat...
