Answer: Nodes of Ranvier
Step-by-step explanation: The nerve cells are also termed as neurons. Their structure is quite from other kinds of cells. These consist of long and slender region called as axon, with branches at one end, called as dendrites and a head region on the other end, called as cell body. The structure is shared below.
The axon region is covered with mylein sheath, throughout the region except few gaps, which act as the points from where action potential jumps and pass from one neuron to another.
