Question
Required information
Biophoto Associates/Science Source
Keep in mind the location of the nerve fibers in this picture. What impact might this have on cutaneous sensation?
Multiple Choice
Unlike first-degree burns, third-degree burns destroy the nerve fibers in the dermis and may therefore be painless.
Since there are no nerve fibers in the skin, it cannot convey or respond to any sensory information.
A shallow scrape that penetrates into the stratum granulosum may be more painful that a deeper cut that reaches the dermis.
Sensory receptors in the uppermost layers of the epidermis (stratum corneum) respond to heat and cold, making it important for thermoregulation.
Due to the relative density of nerve fibers in the different layers of the skin, the epidermis is much more sensitive than the underlying dermis.
