Why don't I get goosebumps?

This may seem like an odd question, but its one I鈥檝e been trying to find the answer to for years! I have never in my life had goosebumps, no matter how scared, cold, or emotional I may get! I have tried little experiments, like sitting out in the cold %26 shivering, to making myself stare at spiders (I am not a spider lover) but still no bumps! I have spoken to some v intelligent people about this, but nobody has ever come up with a plausible answer!
Answer:
Ok goosebumps or piloerection (pil is from the Latin word for hair). People experience this phenomenon when they are cold or frightened. The hair is able to stand on end due to the contraction of the pili muscles at the base of the hairs. When they are triggered by external stimulus, the tiny muscles become hyperactive and the hair stands up straight. Because humans have very short hairs, our highly visible skin displays many small bumps as the pili muscles contract.Piloerection as a response to cold or fear is vestigial in humans; as humans retain only very little body hair, the reflex (in humans) now serves no known purpose.
The tiny mucsles are called Arrectores pilorum: Tiny muscles that act as the hair erector muscles. The arrectores pilorum play a key role in goose bumps, a temporary local change in the skin The chain of events leading to this skin change starts with a stimulus such as cold or fear. That stimulus causes a nerve discharge from the sympathetic nervous system, a portion of the autonomic (involuntary) nervous system. The nerve discharge causes contraction of the arrectores pilorum (the hair erector muscles). Contraction of these muscles elevates the hair follicles above the rest of the skin. And it is these tiny elevations we perceive as goose bumps.I cant say why you dont get goosebumps it might be that you haven't be exsposed to the right stimuli to create the response or it may be genetic. If you can make sense of the passge below(see second link) it talks about the lack of certain things in one person while they are clearly there in the control subjects. All to do with the nerve ending of the arrector pili smooth muscles/Arrectores pilorum muscle.We studied the immunohistochemical expression of laminin subunits f2, f1, g1 in muscle and skin biopsy samples from three patients with congenital muscular dystrophy (CMD), and from ten control patients investigated for various neuromuscular disorders. Merosin f2 chain was not detectable in the basement membrane of muscle fibers, or in the nerve endings, cutaneous nerves, and corium in the skin of the CMD patients, whereas it was clearly expressed in the skin biopsy samples from control patients, especially in the nerve endings of the arrector pili muscles. Laminin f1 chain was expressed in the corium, in the muscle fiber membranes of arrector pili muscles and in cutaneous nerve fibers, perineurium and blood vessels in controls and in CMD patients. Laminin g1 chain was faintly expressed in the corium, and a diffuse labeling was detected on arrector pili muscle with enhanced expression at nerve endings, intracutaneous nerves and capillaries, with similar findings in all biopsy specimens. For merosin-negative CMD patients, skin biopsy may provide a diagnostic alternative to muscle biopsy since merosin deficiency can be demonstrated in the skin neural structures, and in particular in the nerve endings of the arrector pili smooth muscles
(I gave up reasearching here as it was beyond me)Hope you find out why you dont get goosebumps. I think you need to really test the response try doing some exersise until you hot and swaeting then jump into a cold shower or a bath. This should give you. goose bumps. Good luck

are you asking to make a monster out of you?

Interesting. Well, I get them ALL the time..I'll share!!

---

I can't remember it all but somebody told me that years ago when a goose was killed it got bumps in fright and thats where the sayin came from,goosebumps

hmmmmmmmmm, if intelligent people don't have the answer maybe there isn't one.
