What function of the skin includes sensation of touch, heat, cold, pressure, and pain?

• A. Protection
• B. Sensation
• C. Absorption
• D. Excretion

Answer: (B)

Sensation is the skin’s function here. Nerve endings and specialized receptors in the skin detect mechanical stimuli (touch and pressure), temperature (heat and cold), and noxious stimuli (pain), sending signals to the brain to produce our sense of touch, temperature, and pain. Mechanoreceptors, thermoreceptors, and nociceptors work together to interpret the environment and protect us. The other roles—protection as a barrier, absorption of some substances, and excretion through sweating—do not primarily explain the perception of these sensory inputs.
