Which type of nerve fibers transmit messages from sense organs to the spinal cord and brain?

Explanation:
Messages from sense organs to the spinal cord and brain travel via sensory (afferent) nerve fibers. The term afferent means “toward the CNS,” so these fibers carry information from the periphery into the central nervous system for processing. In contrast, motor (efferent) nerves send commands from the CNS to muscles and glands. Interneurons exist within the CNS to connect neurons, and mixed nerves contain both sensory and motor fibers, but the question specifically asks for the fibers that bring information from sense organs into the CNS, which are sensory (afferent) fibers.
