What is the function of sensory neurons?

Sensory neurons play a crucial role in the nervous system by carrying messages from sensory receptors—such as those in the skin, eyes, and ears—to the brain. This process enables the brain to interpret signals from the environment, facilitating perceptions such as touch, taste, sight, sound, and smell. Sensory neurons are integral for initiating reflexes and for the brain to process information, making the selection of this option the most accurate representation of the function of sensory neurons.

In the context of the other options, while the brain does communicate with muscles through different types of neurons, that functionality is associated with motor neurons, not sensory neurons. Furthermore, signals from interneurons are relayed between other neurons, and controlling motor functions pertains to motor neurons and not the sensory pathways involved in sensation.
