An injury to the skin or tissue and muscle in any area can cause temporary or permanent loss of

• A. Taste
• B. Color vision
• C. Hearing
• D. Touch input processing

Answer: (D)

When skin or underlying tissues are injured, the nerves and receptors responsible for sensing touch can be damaged. The skin houses mechanoreceptors that detect light touch, pressure, and vibration, and these signals travel through peripheral nerves to the brain. If those pathways are disrupted by injury, touch sensation in that area can be reduced or lost, either temporarily while healing or permanently if nerve damage is severe. Taste, color vision, and hearing involve different sensory systems (taste buds, photoreceptors in the eye, and the inner ear), so they aren’t directly affected by skin injury. So the impairment most likely resulting from such an injury is loss of touch input processing.
