The gaps between successive Schwann cells along a myelinated axon are called
- A. nodes of Ranvier
- B. synaptic clefts
- C. dendritic spines
- D. neurofibril nodes
Explanation
At the nodes the axon membrane is exposed and rich in ion channels, so the action potential jumps from node to node in saltatory conduction. This jumping is what makes myelinated fibres conduct many times faster than unmyelinated ones.
