Detailed explanation-1: -Specialized cells and tissues within these organs receive raw stimuli and translate them into signals the nervous system can use. Nerves relay the signals to the brain, which interprets them as sight (vision), sound (hearing), smell (olfaction), taste (gustation), and touch (tactile perception).
Detailed explanation-2: -The sensation of touch is mediated by mechanosensory neurons that are embedded in skin and relay signals from the periphery to the central nervous system. During embryogenesis, axons elongate from these neurons to make contact with the developing skin.
Detailed explanation-3: -Sensory input. The other senses on your head-sound, smell, taste and touch-all use your somatic nervous system to reach your brain. Your sense of touch below your neck uses your somatic nervous system to reach your spinal cord, which then relays signals to your brain.
