Let’s keep going deeper down as the thick mass of connective tissue called the dermis, and lower lying fat cells, act as shock absorbers, padding the body’s inner tissues from outside blows.
The innate intelligence of the body uses blood vessels to help regulate temperature, widening or constricting them, to release or conserve heat. On cold days the erector pili muscle contracts, causing the hair to stand up. In animals their reaction traps an insulating layer of warm air near the skin. In humans it results only in goose bumps.
Snaking through this environment is a warning system of berve fibers that terminate in endings, either free or enclosed in corpuscles. This network tingles in response to touch, pressure, heat and cold, alerting the brain to the world outside… specially during holidays. 🙂
Amazing isn’t it?
