What type of neuron would process incoming sensory signals?

The correct choice is afferent neuron, which is specifically designed to transmit sensory information from sensory receptors to the central nervous system. These neurons carry signals that reflect external stimuli such as light, sound, temperature, and pressure, allowing the brain to process and respond to the environment appropriately.

Afferent neurons are integral to the sensory pathways, as they serve as the first point of contact for sensory input, converting physical stimulus into electrochemical signals that can be interpreted by the nervous system. Through this process, they play a crucial role in how we perceive and interact with the world around us, making them essential for sensory function.

In contrast, motor neurons are tasked with carrying signals away from the central nervous system to muscles and glands, thereby facilitating movement rather than processing incoming signals. Interneurons serve to connect afferent and efferent neurons within the central nervous system, acting as relay points and processing information, but they do not directly process the initial incoming sensory signals themselves. Efferent neurons, similar to motor neurons, are responsible for conveying signals that lead to action or response rather than receiving sensory information.
