In a reflex arc, what is the role of an interneuron? 

Interneurons, also known as associative neurons or connector neurons, are a crucial type of neuron found within the central nervous system (CNS). They play a fundamental role in transmitting information and facilitating communication between sensory neurons and motor neurons. Unlike sensory neurons that bring information from sensory receptors to the CNS, and motor neurons that carry instructions from the CNS to muscles and glands, interneurons operate entirely within the CNS.
