Which neurons receive and carry sensory information from the external world?

• A. Sensory Neurons
• B. Motor Neurons
• C. Interneurons
• D. Glial Cells

Answer: (A)

The key idea is the role of sensory neurons in detecting and conveying information from the outside world to the brain. Sensory neurons are specialized to receive input from sensory receptors that respond to external stimuli—such as touch, hearing, or light—and then transmit that information along peripheral nerves toward the central nervous system. In contrast, motor neurons carry signals from the brain or spinal cord to muscles to cause movement, interneurons mainly connect neurons within the CNS to process information, and glial cells provide support to neurons rather than transmitting sensory signals themselves. So, the type that receives and carries sensory information from the external world is sensory neurons.
