Adrenal Medulla
The adrenal medulla is responsible for inducing goose flesh, also known as goosebumps or piloerection. This response is triggered by the release of adrenaline (epinephrine) and noradrenaline (norepinephrine) from the adrenal medulla in response to stress, fear, or excitement.
Goose Flesh
When the adrenal medulla releases adrenaline and noradrenaline, these hormones cause the erector pili muscles at the base of hair follicles to contract. This contraction causes the hair to stand on end, creating the appearance of goosebumps on the skin.
Function
The purpose of goosebumps is a vestigial reflex that dates back to our evolutionary ancestors. In animals with thicker fur, raising the hair would trap air and create an insulating layer to keep them warm. In humans, this response is less functional but is still triggered in response to stress or cold temperatures.
Conclusion
In conclusion, the adrenal medulla is responsible for inducing goose flesh by releasing adrenaline and noradrenaline, causing the erector pili muscles to contract and creating the appearance of goosebumps on the skin. This physiological response is a remnant of our evolutionary past and is triggered in situations of stress, fear, or excitement.
