Somatic sensation usually describes sensations arising from the skin.

• A. From the skin
• B. From bones
• C. From internal organs
• D. From the brain

Answer: (A)

Somatic sensation refers to the body's surface and musculoskeletal inputs, with the skin housing the primary receptors for touch, temperature, and pain. These cutaneous receptors provide the sensations we typically label as somatic—things we feel on or just under the skin. Internal organs generate visceral senses (like hunger or fullness) that are distinct from somatic sensations, and the brain is the processing center rather than the source of these sensory signals. That’s why sensations described as somatic usually arise from the skin.
