Which of the Following is Most Likely to Be Myelinated

Question

Which of the following is most likely to be myelinated?
A)an interneuron
B)the axon between your spinal cord and your big toe
C)an axon that only exists within the spinal cord
D)a neuron in the thalamus

Accepted Answer

The axon between your spinal cord and your big toe is a sensory neuron and is likely to be myelinated in order to facilitate faster conduction of signals over long distances. Myelination is particularly important for neurons that need to transmit signals quickly and efficiently over large distances.
