Because it didnt have a stimulus to activate depolarization
A relay neurone passes impulses from a sensory neurone to a motor neurone.
interneuron
The stimulus is detected by the sensory receptor. The sensory receptor stimulates a sensory neuron. The sensory neuron transmits to the interneuron in the spinal cord. The interneuron stimulates a motor neuron. The motor neuron communicates to the muscle. The muscle(effector) then produces the response allowing the body to respond to the stimulus.
Disturbances to sensory neurons can cause depolarization of the neuron's membrane, reaching a threshold that triggers an action potential. This action potential then travels along the neuron's axon to the central nervous system, where it is processed and interpreted as a sensory experience.
Interneurons are located in the spinal cord. They act as the middlemen in transmitting signals between sensory neurons (that detect stimuli) and motor neurons (that generate a response). In a spinal reflex pathway, after receiving sensory input from a sensory neuron, the interneuron processes the information before signaling the motor neuron to carry out a response.

Essentially, it is the interneuron. The body has numerous sensory receptors. The sensory receptors are stimulated an send their signal to the central nervous system and synapse or connect with an interneuron which is the processing center. The interneuron then synapses or connects with the motor neuron which sends a message/instruction by way of the motor neuron to skeletal muscle, smooth muscle, cardiac muscles, or glands. This is true, but to add more information, the Interneuron is also known as "relay neuron", "association neuron" or "local circuit neuron".Source:http://en.wikipedia.org/wiki/Interneuron

There are 3 types, the motor neuron, the sensory neuron, and the interneuron

In a typical reflex arc, the 3 kinds are: # sensory # interneuron # and motor.
