Impulse conduction is fastest in neurons that are:

  • A. myelinated
  • B. unmyelinated
  • C. sensory
  • D. motor
Correct Answer: A

Rationale: Myelinated neurons conduct impulses faster than unmyelinated neurons due to saltatory conduction, where the signal jumps between nodes of Ranvier. Sensory, motor, and cerebral neurons can be myelinated or unmyelinated, but myelination is the key factor for speed. Thus, A is the correct answer.
