Which of the following is associated with the fastest neural impulses

A)  unmyelinated dendrites 
B)  myelinated axons 
C)  shorter axons 
D)  multiple dendrites

Myelinated axons are associated with the fastest neural impulses because myelin acts as an insulator that prevents the dissipation of electrical signals as they travel down the axon. This allows the impulses to propagate faster along the axon. Unmyelinated dendrites and shorter axons would actually slow down neural impulses, while multiple dendrites do not play a role in the speed of neural impulses.
