Relay neurons, also known as interneurons, play a critical role in the nervous system by serving as connectors between sensory and motor neurons. They facilitate communication by processing and transmitting signals from sensory neurons, which receive stimuli from the environment, to motor neurons, which generate responses by triggering muscle contractions or glandular activity.

Relay neurons are primarily found in the central nervous system (CNS), where they contribute to reflex arcs and complex neural pathways. Their ability to integrate and relay information allows for quicker responses to stimuli, as they can also involve additional processing, such as decision-making or coordination of multiple signals.

Motor neurons are responsible for carrying signals away from the CNS to effectively execute movements, while sensory neurons carry signals from sensory receptors to the CNS. Purkinje neurons are a specific type of neuron found in the cerebellum and are primarily involved in motor control, but they do not serve the specific role of connecting sensory and motor neurons.
