Best Answer

Reflex nerve pathway is a monosynaptic transmission. There are no interneurons involved. Only the limb that carries the afferent nerve impulse from the stimulus and the efferent motor function for the reflex involved. That is why it is faster. Normal nerve transmission require an interpretation of the impulse by the brain whereas reflex pathways do not. Another reason is because most reflexes from the exteroreceptors travel along myelinated axons (white matter) which carry the impulse faster than other neurons that have unmyelinated axons (grey matter).
