Question

Two factors serve as the major determinants for how rapidly a neuron is able to conduct electrochemical impulses, these include the presence/absence of a myelin sheath along the length of the axon and the diameter of the axon. Following are a variety of combinations of these two characters a neuron might possess. From the options listed, select the neuron what would transmit electrochemical signals most rapidly.

Question 6 options:

wide-diametered axon that is myelinated

wide-diametered axon that is non myelinated

narrow-diametered axon that is myelinated

narrow-diametered axon the is non myelinated

wide-diametered axon that is myelinated

wide-diametered axon that is non myelinated

narrow-diametered axon that is myelinated

narrow-diametered axon the is non myelinated

Explanation / Answer

myelin acts a electrical insulator and signals travel 20times faster and larger wide diametered axon favors faster transmission of impulse. so option A
