Another name for a relay neuron is the ______.

Another name for a relay neuron is the ______.

• A. Interneuron
• B. Motor neuron
• C. Sensory neuron
• D. Neuron

Answer: (A)

Relays neurons, or interneurons, operate entirely within the central nervous system to pass signals from one neuron to another. They sit between sensory neurons and motor neurons, receiving input from a sensory neuron and transmitting the message onward to a motor neuron, which then activates an effect. This arrangement is key in reflexes and in processing information in the spinal cord and brain. A sensory neuron brings information from a stimulus to the CNS, but it doesn’t relay to other neurons within the CNS. A motor neuron carries the signal from the CNS to an effector like a muscle. A general neuron isn’t specific to the connective role. So the term that best fits a relay neuron is interneuron.
