Along a nerve cell, the impulse travels from the axon to the dendrites and then again to the axons through the synapse.
It starts in the nerve through the roots then the spinal cord then to the nerve.

the nerve pathways followed by an impulse during a reflex.
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).
Sensation is carried by sensory nerve fibres. Then you have intermediate neuron. Then motor neuron. Nerve signal travels along the tract to give rise to reflex action. Simultaneously, the impulse is sent to brain.
The nerve impulse travels through the reflex arc. It travels from the sensor through the sensory neurone, through the spinal cord and motor neurone to the effector muscle.
