Sensory neurons are responsible for transmitting sensory information from sensory receptors to the central nervous system (CNS). These neurons play a crucial role in the sensory pathways by detecting stimuli from the environment, such as light, sound, touch, and chemical signals, and converting those signals into electrical impulses. Once these impulses reach the CNS, they can be processed, allowing for perception and response to the stimuli.

This mechanism is essential for functioning in everyday life, as it allows organisms to perceive their environment and react accordingly. In contrast, the other options describe functions associated with different types of neurons. For example, the role of carrying information from the CNS to muscles pertains to motor neurons, while intervening between sensory inputs and motor outputs refers to interneurons. Thus, the focus on the function of sensory neurons in conveying information to the CNS clarifies why this choice is the most accurate regarding their role in the nervous system.
