Which statement about the skin senses is true?

• A. Sensations for hotness are produced by stimulation of specialized receptors for heat.
• B. All skin receptors can respond to more than one type of stimulation.
• C. There are about ten thousand receptors for touch distributed throughout the body.
• D. Sensory information is transmitted from the spinal cord to the somatosensory cortex.

Answer: (D)

The correct statement about the skin senses highlights the pathway of sensory information from the spinal cord to the somatosensory cortex. This pathway is crucial for our understanding of how the brain processes touch, pain, and temperature. After the skin senses detect various stimuli, that sensory information is relayed through the peripheral nervous system to the spinal cord. From there, it is transmitted to the somatosensory cortex, which processes the information and enables us to perceive sensations such as touch, pressure, and temperature. This connection conveys why the perception of skin sensations is intricately tied to the brain's somatosensory region. The other statements do not accurately reflect the complexities of the skin senses. For example, while it is true that hot sensations do arise from the responsiveness of certain receptors, these sensations are actually a response of a combination of receptors rather than specialized receptors solely dedicated to heat. Similarly, although skin receptors may have multi-functional capabilities, the claim regarding the number of receptors for touch is misleading; the number is much higher than ten thousand, indicating a more extensive sensory network than suggested.
