questions for Mushroom!!
-
i reckon it'll be easier to post my questions here and wait for replies whenever mushroom's free... easier to refer to them in the future as well.... hope u dun mind, mushroom.
1) why do we get pins and needles when we sleep in an inappropriate posture? what causes it? how does that change to total numbness (eg. cant even feel my arm)? how does the numbness get reversed when u let the blood flow there again?
2) most humans are trichromatic in their vision. that is due to the 3 kinda of cones we have. i hear that some primate species are dichromatic, having only have 2 kinds of cones (opsin proteins being coded for in the X chromosome). hence, some female monkeys with heterzygosity for those opsin genes are actually trichromatic. what about humans? are there human females who are tetrachromatic?
3) there is a recent new health product in the market, transdermal glucosamine. does that really work? can u actually get the glucosamine to be absorbed right down to your bones, much less for bone strengthening?
4) why does salt cause our food to taste much better, when if taken alone causes anyone to frown? is there a science as to how the "taste" of salt in registered in our tastebuds?
5) some people now use sweeteners instead of sugar for their coffees and tea. once, i added a few of those Equal "pills" into my tea. the first sip of the tea and i thought, oh sht, i might have added too much. but subsequent sips didnt taste all that sweet afterall. it was as if i hadnt even added any sweetener at all. wad is going on?
6) when different people sneeze, they sound different. there's the very loud ones. there's the "hold nose and a small nasal snort comes out" kind. there are people who "abort" a sneeze only to utter "achoo" a sec later. how do we all sneeze differently?
7) what exactly are moles? (i dunno if i've asked this already, but i still dun quite understand). how do they begin? how do they disappear? why are some persistent.
this one is about THE embarrassing part of the male anatomy.... 
i've heard that one can gradually increase ITS length by pulling on it a bit every day, much like trying to stretch a muscle. except that we all know that THAT isnt a muscle at all.... my question is: does pulling really help? 
ok, that ends my questions for now... there is no hurry. just answer in ur own time. dun need to answer all at one sitting lah.... i want detailed answers, not rushed semi-answers. really appreciate it.
when it comes to this, i suppose anyone with questions to mushroom also can post here ba. and if anyone knows any information on the above questions, also can help me answer them.
gracias!! -

It is known as temporal paresthesia which is caused by pressure on a nerve or lack of blood flow to afflicted area. Once circulation is restored, sensation and control returns. -

Note that most biological neural functions are activated in "pulses" due to the way the central nervous system works. "Pins and needles" happens to be the most accurate description of the effect. And if you had bothered to read my posting carefully, pressure on a nerve point may also cause similar effects. If you don't believe, try knocking your funny bone on your elbow and note its effect.Originally posted by starblue:i know this much. but.... i want more details as to the intricate underlying mechanisms at work here. why pins and needles. why is the pain in "pulses"? what is stimulating it? why doesnt the skin change colour if the blood circulation is blocked? -

Q2) Most humans are trichromatic in their vision. that is due to the 3 kinda of cones we have. i hear that some primate species are dichromatic, having only have 2 kinds of cones (opsin proteins being coded for in the X chromosome). hence, some female monkeys with heterzygosity for those opsin genes are actually trichromatic. what about humans? are there human females who are tetrachromatic?
Commonly the 3 photo pigment of cones we have in our eyes are Red, Blue, Green. This enables us to see colors.
But for tetrachromatic, they have 4 photopigment cones.A recent paper by Kimberly Jameson, Susan Highnote and Linda Wasserman of the University of California, San Diego, concerning females who may have tetrachromacy shows amazing results. Up to 50 per cent of women are tetrachromatic and can use their extra pigments in "contextually rich viewing circumstances". For example, when looking at a rainbow, tetrachromat females can segment it into, on average, 10 different colours, whereas their trichromat brothers and sisters can see only seven, much as Isaac Newton's red, orange, yellow, green, blue, indigo and violet. Consequently, for those special tetrachromat women, this island that they inhabit may be seen in emerald, jade, verdant, olive, lime, bottle and 34 other shades of green. Apparently, men and women do see the world differently.

SQ3) there is a recent new health product in the market, transdermal glucosamine. does that really work? can u actually get the glucosamine to be absorbed right down to your bones, much less for bone strengthening?
Transdermal - A medicated adhesive patch that is placed on the skin to deliver a time released dose of medication through the skin and into the bloodstream.
Glucosamine - Since glucosamine is a precursor* for glycosaminoglycans, and glycosaminoglycans are a major component of joint cartilage, supplemental glucosamine may help to rebuild cartilage and treat arthritis.
Precursor - A compound that participates in the chemical reaction that produces another compound

Q4) Why does salt cause our food to taste much better, when if taken alone causes anyone to frown? is there a science as to how the "taste" of salt in registered in our tastebuds?
The major components of our common salt is Sodium Chloride. It has flavour enchancing property.
Not too sure about the latter questions.

Q5. Some people now use sweeteners instead of sugar for their coffees and tea. once, i added a few of those Equal "pills" into my tea. the first sip of the tea and i thought, oh sht, i might have added too much. but subsequent sips didnt taste all that sweet afterall. it was as if i hadnt even added any sweetener at all. wad is going on?
SA5)Ya. Equal is vvvvvvvery sweet.
My best guess.
First sip is too sweet and cause a neurosignal overflow. That's explain why subsequent sips doesn't taste as sweet as the first one.
Q6) when different people sneeze, they sound different. there's the very loud ones. there's the "hold nose and a small nasal snort comes out" kind. there are people who "abort" a sneeze only to utter "achoo" a sec later. how do we all sneeze differently?
SA6) Each and every individual is unique.
Sneezeing is involuntary action. But during the process of sneezing, you can control one thing. The amount of air being forced out by the lungs. Those louder ones are caused by forcing out air from the lung.
Q7) what exactly are moles? (i dunno if i've asked this already, but i still dun quite understand). how do they begin? how do they disappear? why are some persistent.

About question 8 ar..
I don't have any idea on that. -
1) why do we get pins and needles when we sleep in an inappropriate posture? what causes it? how does that change to total numbness (eg. cant even feel my arm)? how does the numbness get reversed when u let the blood flow there again?
Paraesthesia is the abnormal sensation you feel because the nerves have been stimulated. In clinical medicine, pins and needles or 'pain shooting up' the arm or legs may indicate a disease condition affecting the nerves. E.g. if you get a slipped disc that pinches on a nerve root taht supplies the leg, you get shooting pain down the leg. Some diabetic patients with peripheral neuropathy complain of pins and needles, possibly because it is the small sensory nerves that are primarily damaged in diabetes.
The pins and needles you get when you sleep in an awkward position is because the blood supply is compromised (not completely cut off). Actually you get the sensation AFTER blood supply has been restored. Most likely that relates to the build-up of metabolites during the period of relative hypoxia. The return of blood supply to the region stimulates the nerves, possibly because the high lactic acid and other metabolites in the vasa nervorum.
There is a rich vascular plexus in the skin with communicating channels. It is harder to compromise blood supply to the skin just because your arm is hanging over the edge of your bed. On the other hand, a major blood vessel in the arm. e.g your brachial artery may well be compressed with your arm in the position. The blood supply is reduced, but not cut off (or you would have lost your arm in the morning). The buildup of metabolites distal to the obstruction causes your pins and needles.
Actually, as with all forms of pain, paraesthesia is a warning sign that something is not right. If you ignore it and the inciting cause persists eg. disk prolapse and diabetes, eventually the pins and needle sensation will stop when those nerves are completely dead.
2) most humans are trichromatic in their vision. that is due to the 3 kinda of cones we have. i hear that some primate species are dichromatic, having only have 2 kinds of cones (opsin proteins being coded for in the X chromosome). hence, some female monkeys with heterzygosity for those opsin genes are actually trichromatic. what about humans? are there human females who are tetrachromatic?
I am not aware of such a gender difference but sorry, it's not my field.
3) there is a recent new health product in the market, transdermal glucosamine. does that really work? can u actually get the glucosamine to be absorbed right down to your bones, much less for bone strengthening?
Really? Transdermal glucosmine? I do not know of the product and so I cannot really comment. But I would be very skeptical that an ionic compound can penetrate the lipid membranes of the keratinocytes, unless they have somehow conjugated the glucosamine to a lipid molecule. Even so, I have never been particularly convinced of the usefulness of such nutrient supplements. Ask the supplier for scientific publications and then we'll see. -
1) Paraesthesia is "pain shooting up the leg"?? sometimes when i wake up in the morning, then go stand at the sink to brush up, i will experience this throbbing pain in the leg. i always reckon it's cos the muscles havent "wake up" yet, and the stiffness in my stance overexerts the mucles and nerves causing the pain. cos when i move my weight to the other leg, then the pain lessens and eventually disappears. when i move my weight back to the throbbing leg (before the pain stops completely), the throbbing increase back.Originally posted by oxford mushroom:1) why do we get pins and needles when we sleep in an inappropriate posture? what causes it? how does that change to total numbness (eg. cant even feel my arm)? how does the numbness get reversed when u let the blood flow there again?

what is going on here? maybe some major blood vessels are being blocked (hence the pain throbbing in sync with my heart beat)??

thanks for the info... gives me some platform to do some research of my own. especially the one on the 5 visual channels in pigeons.Originally posted by Darkness_hacker99:Q4) Why does salt cause our food to taste much better, when if taken alone causes anyone to frown? is there a science as to how the "taste" of salt in registered in our tastebuds?

Not too sure about the latter questions.
http://en.wikipedia.org/wiki/Sodium_chloride
this doesnt tell much about how our taste buds interact with salt to produce the phenomenon i stated in my question.
Q5. Some people now use sweeteners instead of sugar for their coffees and tea. once, i added a few of those Equal "pills" into my tea. the first sip of the tea and i thought, oh sht, i might have added too much. but subsequent sips didnt taste all that sweet afterall. it was as if i hadnt even added any sweetener at all. wad is going on?

this is wad i supposed also. but i am interested in how sweeteners interact differently with our sense of taste from sugar. if u put lots and lots of sugar in your tea, it will taste sweet ALL THE WAY. but with the sweetener, it seems to work in a different manner (involving desensitization somewhere? causing the sweetness to fade after prolonged or intense exposure).
Q6) when different people sneeze, they sound different. there's the very loud ones. there's the "hold nose and a small nasal snort comes out" kind. there are people who "abort" a sneeze only to utter "achoo" a sec later. how do we all sneeze differently?

SA7) http://en.wikipedia.org/wiki/Mole_(skin_marking)
the mole in the website seems to be the more "abnormal" looking ones... i am talking about those normal black dots on the skin. how do they form (from scratch). why do they remain that position and even that size and colour throughout your years (even though your layers of skin cells are constantly being slothed off by friction and replaced). -

Throbbing pain in sync with heart beat...obviously vascular in origin. Quite different from nerve pain, often described as shooting pain or pins and needles. Nothing to worry about and probably related to posture. Incidentally, migraine is also vascular...the blood vessels constrict for soem reason and then dilate, causing the throbbing pain.Originally posted by starblue:1) Paraesthesia is "pain shooting up the leg"?? sometimes when i wake up in the morning, then go stand at the sink to brush up, i will experience this throbbing pain in the leg. i always reckon it's cos the muscles havent "wake up" yet, and the stiffness in my stance overexerts the mucles and nerves causing the pain. cos when i move my weight to the other leg, then the pain lessens and eventually disappears. when i move my weight back to the throbbing leg (before the pain stops completely), the throbbing increase back.

Here's a qian bian question:
Why Oxford Mushroom cannot be used for Cream of Mushroom Soup? -
4) why does salt cause our food to taste much better, when if taken alone causes anyone to frown? is there a science as to how the "taste" of salt in registered in our tastebuds?
No, I do not why. I think one of the regular forumners is into nutritional science....she can probably answer this question better.
5) some people now use sweeteners instead of sugar for their coffees and tea. once, i added a few of those Equal "pills" into my tea. the first sip of the tea and i thought, oh sht, i might have added too much. but subsequent sips didnt taste all that sweet afterall. it was as if i hadnt even added any sweetener at all. wad is going on?
Really? Equal contains aspartame, I think, and that is many times sweeter than sugar weight for weight. At one time there was some concern about health risks (not proven) and I wonder if they have lowered the concentration. I can tell the difference between the sweetness with ordinary sugar and that of aspartame. Perhaps your sense of taste is better developed than most and so you are able to distinguish the sweetness of aspartame as being a different flavour rather than recognizing it as sweet. This is not my field and perhaps we can hear from a nutritionist.
Incidentally, the BBC had a programme talking about those who are fussy eaters tend to have more prominent taste buds and so are better able to distinguish between flavours compared to most others. Maybe you are one of them.
6) when different people sneeze, they sound different. there's the very loud ones. there's the "hold nose and a small nasal snort comes out" kind. there are people who "abort" a sneeze only to utter "achoo" a sec later. how do we all sneeze differently?
A sneeze is a forceful expulsion of air from the lungs initiated by nerve endings in the nasal mucosa. An irritant in the trachea results in a cough. Actually the two are quite similar: forced contraction of the diaphragm and chest wall to expel air in a bid to remove the irritant. Although the sneeze response is mostly involuntary, the way the air is directed will result in different sounds. Some people direct air out completely through the nose and mouth, others consciously try to hold it down. Try it: next time you sneeze, try to modify the sound by directing it differently.
7) what exactly are moles? (i dunno if i've asked this already, but i still dun quite understand). how do they begin? how do they disappear? why are some persistent.
ok...I know a bit more about this. Moles are localised skin pigmentation due to local proliferation of melanocytes. Quite a number of conditions are called 'moles'. In general, they are a response to sunlight and there are strong genetic and racial influences.
A uniform increase in the number of melanocytes at the dermal-epidermal junction in a linear fashion produces a lentiges or ephilis. That is a flat patch of skin pigmentation. What is commonly recognized as a 'mole' is a melanocytic nevus. That is a nest or nests of melanocytes. They usually start at the dermal-epidermal junction as a 'junctional nevus' and then drop into the dermis as they mature. If the nests are completely located in the dermis, they are called an 'intradermal nevus' (and are often raised as a nodule). If it is located in both locations, it is a compound nevus.
Melanocytic nevus can persist or with time, they may mature and be replaced by fat (lipomatous metaplasia). Sometimes an inflammatory reaction occurs against the mole, destroying the melanocytes and producing a halo nevus as the edge of the mole loses its pigmentation due to lymphocytic attack. very rarely, some cases can turn malignant and become a melanoma. I do not know why some moles regress and others persist. -
