The gaps between successive Schwann cells along a myelinated axon are called
Correct answer: A. nodes of Ranvier
- 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.

About Receptors
Receptors are specialized cells or proteins that detect stimuli such as light, sound, pressure, temperature and chemicals, then initiate responses through sensory or hormonal pathways. Questions distinguish sensory receptors from effectors, compare receptor types, and examine stimulus conversion into nerve impulses, including the roles of rods, cones, chemoreceptors and mechanoreceptors.
