Identifying Neuron Types in Reflex Actions

Within the human nervous system, various types of neurons play crucial roles in transmitting signals. Consider a situation where an individual quickly withdraws their hand from a hot surface, illustrating the nervous system's protective function. In this reflex action, certain types of neurons are primarily responsible for carrying signals from the sensory receptors to the spinal cord and back to the muscles. Understanding this process involves knowing the different roles of sensory neurons, motor neurons, and interneurons. Based on your knowledge of the nervous system, which type of neuron is primarily responsible for conveying sensory information related to this reflex action?
