Which neuron type is primarily involved in transmitting sensory information to the central nervous system?

• A. Motor neurons
• B. Interneurons
• C. Sensory neurons
• D. Myelinated neurons

Answer: (C)

Sensory neurons are primarily responsible for transmitting sensory information from sensory receptors to the central nervous system (CNS). These specialized neurons detect various stimuli from the environment, such as touch, temperature, pain, and proprioception, converting these signals into electrical impulses. Once activated, sensory neurons send these impulses through their axons to the spinal cord and brain, where the information is processed, leading to perception and response. Motor neurons, on the other hand, carry signals away from the CNS to initiate movement, while interneurons serve as connectors between neurons within the CNS, processing information and relaying signals. Myelinated neurons refer to neurons that are surrounded by a myelin sheath, which helps increase the speed of signal transmission, but this term does not specify the function related to sensory information transmission. Thus, sensory neurons are the key players in conveying sensory data to the CNS.
