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).
reflex arc
Afferent pathway
The reflex arc allows sensory neurons to synapse in the spinal cord instead of the brain, allowing actions to occur relatively quickly by activating spinal motor neurons without needing to send signals through the brain. For example, a person touching a hot stove would flinch before thinking about it, and protect tissues from further damage.

A two-neuron motor pathway.
It is called a reflex arc.
Reflexes are rapid involuntary responses to a given stimuli. The reflex pathway that only has one synapse in the CNS is called the monosynaptic reflex arc.
