What is a key characteristic of a sensory neuron?

• A. Transmits impulses to muscles
• B. Conducts impulses away from the CNS
• C. Transmits signals from receptors to the CNS
• D. Facilitates interneuronal communication

Answer: (C)

A key characteristic of a sensory neuron is its role in transmitting signals from sensory receptors to the central nervous system (CNS). Sensory neurons are specialized to pick up stimuli from the environment, such as light, sound, touch, taste, and smell. Once these stimuli are detected, sensory neurons convert them into electrical impulses and send this information to the CNS, allowing the brain to process and respond to these sensations. This function is crucial for enabling organisms to perceive their surroundings and react appropriately. The accurate transmission of sensory information is foundational to sensory perception and is distinct from the roles of other types of neurons. For instance, motor neurons are responsible for transmitting impulses to muscles to facilitate movement, while interneurons are involved in connecting other neurons within the CNS for communication and processing of information.
