What type of nerve cell is responsible for transmitting sensory information?

• A. Motor neurons
• B. Interneurons
• C. Sensory neurons
• D. Supporting cells

Answer: (C)

The correct response highlights that sensory neurons are specifically designated for the task of transmitting sensory information from sensory receptors to the central nervous system. These neurons are equipped with specialized endings that react to various stimuli such as light, sound, temperature, and pressure. When these sensory receptors detect a stimulus, they convert it into electrical signals that travel along the sensory neurons toward the brain or spinal cord, allowing the body to interpret and respond to the environment.

Motor neurons, by contrast, are responsible for conveying signals from the central nervous system to muscles or glands, facilitating movement and action. Interneurons act as connectors within the nervous system, processing information between sensory and motor neurons, but do not primarily conduct sensory information. Supporting cells, also known as glia, provide structural support, nourishment, and protection to neurons but do not play a direct role in transmitting sensory information.

Understanding these distinctions clarifies the pivotal role sensory neurons play in the overall function of the nervous system, linking external stimuli to the brain for processing and response.
