Question 1 of 5
Which of the following cell(s) produce a compound that insulates nerve axons and greatly increases the speed of transmission (conductance)?
Correct Answer: B
Rationale: The correct answer is B: Schwann cells and oligodendrocytes. Schwann cells produce myelin in the peripheral nervous system, while oligodendrocytes produce myelin in the central nervous system. Myelin insulates nerve axons, allowing for saltatory conduction, greatly increasing the speed of transmission. Nodes of Ranvier are gaps in the myelin sheath where action potentials are regenerated, not where myelin is produced. Neurons themselves do not produce myelin. Astrocytes and ependymal cells have supportive roles in the nervous system but do not produce myelin.
