Quizplus · Accepted Answer

Touch modality involves receptors in the skin which send information through sensory neurons that enter the spinal cord directly. From there, the information is sent to the brain for processing. In contrast, vision and hearing information needs to pass through specialized sensory organs and then travel through cranial nerves to reach the brain. The taste modality involves taste buds in the tongue which also have sensory neurons, but they do not directly enter the spinal cord before reaching the brain.
