Gaps in the myelin sheath are called _______.

  • A. nodes of Ranvier
  • B. the synapse
  • C. axonal interstices
  • D. myelinoids
Correct Answer: A

Rationale: Nodes of Ranvier are small gaps in the myelin sheath along the axon of a neuron. These gaps allow for the rapid conduction of nerve impulses through a process called saltatory conduction, where the action potential 'jumps' from one node to the next. This increases the speed and efficiency of neural communication. Nodes of Ranvier are essential for proper nerve function and are found in both the peripheral and central nervous systems.
