lol I wonder if I could hold my nose and still detect the scent of something strong and easily recognizable.
I want to try this experiment!
You probably could, but more likely due to sneaky odor molecules sneaking into your nasal chamber, not due to the olfactory receptors in your skin, because they do not route to the odor-recognizing part of your brain.
So, do they have any point, or are they like the appendix?
rub pepper on elbow. it should work, I never tried it though.
Rapid healing? I'm guessing that is caused by free radicals.
...that your skin has odor receptors?
Your whole body is a nose.
How does this work, are their functions related to perspiration, heat detection etc?
They work the same way as the ones in our noses do (detecting and recognizing odor molecules) but rather than routing that information through the thalamus for conscious recognition, they seem to serve a regulatory function, responding to certain odors by triggering biochemical cascades that regulate how our cells transcribe DNA to produce certain proteins. For example, for reasons no one understands, exposing the skin to the odor of sandalwood triggers a cascade that results in more rapid healing of wounds.
Is joke? I don't get it.
Naw, I just read somewhere that too much antioxidants slow wound healing and I concocted this whole explanation in my head in which both apoptosis and excessive cellular growth (cancer) are caused by free radicals, and both are needed for tissue regeneration therefore free radicals must promote tissue regeneration.
Uhm, I'm not sure if i've explained that right.
Let me try again in an logical-positivist-ish style:
1. Anti-oxidants reduce the presence of free radicals.
2. Extreme concentrations of anti-oxidants are thought to slow tissue regeneration.
3. Extreme concentrations of free radicals are thought to cause apoptosis and excessive cellular growth.
3.1. Free radicals could be a positive factor in tissue regeneration.
END of logical positivist-ish style.
Isn't sandalwood slightly poisonous? That could cause a release of free-radicals.
I'm just idly theorizing here but the concept has it's attractions.
