Question
nodes of Ranvier allow for ________ conduction along an axon.
Solution
The nodes of Ranvier allow for "saltatory" conduction along an axon.
Here's the step-by-step explanation:
-
The nodes of Ranvier are small gaps in the myelin sheath where the axon is exposed.
-
When an electrical signal, or action potential, is sent down the axon, it doesn't move smoothly. Instead, it jumps from one node of Ranvier to the next.
-
This type of conduction is called "saltatory" conduction, from the Latin word "saltare," which means "to leap."
-
Saltatory conduction is faster than continuous conduction because it reduces the amount of membrane that needs to be depolarized during the propagation of the action potential.
-
Therefore, the nodes of Ranvier play a crucial role in speeding up the transmission of nerve impulses.
