Verified step by step guidance1
Understand the components of a reflex arc: it typically involves sensory neurons, interneurons, and motor neurons.
Identify the role of sensory (afferent) neurons: they carry signals from sensory receptors toward the central nervous system (CNS).
Recognize that motor (efferent) neurons carry signals away from the CNS to effectors like muscles.
Focus on the neuron that connects sensory neurons to motor neurons within the CNS; this neuron processes and relays information.
Recall that this connecting neuron is called an interneuron (also known as an association neuron), which integrates sensory input and coordinates motor output.
