erm then what to reject information overload arh?Originally posted by renorenal:Hmmm.... you're not thinking...
-
erm dunno leh emptying?Originally posted by renorenal:Yes, but that's not really the right answer... -
Precisely... they are defensive mechanism (some of them) and better known as flushing than emptying, they ensure that all the chemicals stored up in the body is excreted and evacuated rather than to let it accumulate.Originally posted by hisoka:erm dunno leh emptying? -
Hahaha... nope... try again...Originally posted by hisoka:erm then what to reject information overload arh?
CLUE: when we switch off our room lights at night, everything turns dark, but wait for a few minutes, and we have the ability of night vision

erm i tot emptying of gall bladder is for digestion or absorption of lipids rather than for the excretion of stuff?Originally posted by renorenal:Precisely... they are defensive mechanism (some of them) and better known as flushing than emptying, they ensure that all the chemicals stored up in the body is excreted and evacuated rather than to let it accumulate. -
hm okz i forgot about the heme and such that goes into the bileOriginally posted by hisoka:erm i tot emptying of gall bladder is for digestion or absorption of lipids rather than for the excretion of stuff? -
...and accumulation of it can cause gallbladder infection (cholecystitis) and gallstones if it is not flushed out... so in a sense, u need to flush it out and new supply of bile replaces the old ones...Originally posted by hisoka:erm i tot emptying of gall bladder is for digestion or absorption of lipids rather than for the excretion of stuff? -
abit obviousle but i'll say it, to preserve the night visionOriginally posted by renorenal:Hahaha... nope... try again...

Let others think mar... hahaha...Originally posted by hisoka:hey tell the funny bone leh -
Not even close lar... hahaha... try again...Originally posted by hisoka:abit obviousle but i'll say it, to preserve the night vision

got clue on the anatomical placing of the funny bone? i dun feel like flipping my booksOriginally posted by renorenal:Let others think mar... hahaha... -
ee not fun one all i know is the pupils will change size but dunno why only one eye close lehOriginally posted by renorenal:Not even close lar... hahaha... try again...

You have bits and pieces of correct information thrown everywhere, you just need to fit it all into a puzzle...Originally posted by hisoka:ee not fun one all i know is the pupils will change size but dunno why only one eye close leh -
A bone in your forearm... you only have two, radius or ulna...Originally posted by hisoka:got clue on the anatomical placing of the funny bone? i dun feel like flipping my books
I will supply the answers tomorrow night... or saturday... meanwhile, have fun! -
dun tell me one eye can change faster than the other?Originally posted by renorenal:You have bits and pieces of correct information thrown everywhere, you just need to fit it all into a puzzle...
anyway you go sleep bah have fun -
because its not a boneOriginally posted by renorenal:A bone in your forearm... you only have two, radius or ulna... I will supply the answers tomorrow night... or saturday... meanwhile, have fun! -
Nolar... actually it's both eyes reflexively... I typed too fast, missed out an "s" on the eye (but it doesn't make any difference lar) hahaha... okay... have fun thinking...Originally posted by hisoka:dun tell me one eye can change faster than the other?
anyway you go sleep bah have fun
Gnite! -
It is a bone lar!Originally posted by hisoka:because its not a bone
Second CLUE: NERVE -
dun tell me the bone got nerve oneOriginally posted by renorenal:It is a bone lar!

[b]NEW MYSTERY
When you sleep snuggly at night in your dark comfy room, your lil brother decides to give you a nasty wake-up call... he sneaked into your room and switch on all your bright room lights.
As you open your eyes to see what is going on your eyes hurt and you reflexively close your eye...
Why? [/b]
my guess: e eyes...could it be due to dark adaptation? (it usually takes 30mins to adapt to e dark..therefore, we feel like blindbats whenever we are late for movies in the cinema). since we close our eyes (or in this case when we sleep), we are v used to darkness, hence e threshold is v low to light. therefore e human eye is able to spot light even a few miles away in dark surroundings.
transition to light adaptation: now that e lights are suddenly lighted, it will cause an overwhelming reaction in the eyes, as the rods now are totally bleached (compared to the high levels of rhodopsin in the dark, now are all used up), and now no longer function.
to adapt to light it will take at least 1min. to restore a level of rhodopsin (for the rods and cones to function), maybe e first reflex is to constrict the pupil size, if it doesnt work, then the eyes close to shut light from going in.. -

[b]SPECIAL MYSTERY QUESTION
Before we fall asleep or close to falling asleep, we may feel that we are falling down from a multistorey building or from an airplane without any support. Our body will generate a response by means of jerky movements of all our muscles to prevent us from falling and we often wake up from that reflex.
Do you know what is the phenomenon called and why does it happen? [/b]
not really sure in how to explain, but quite sure that e brain would 'turn off' all motor systems to prevent us from trashing in bed when we have nightmares (stage 4 or REM sleep)..
my guess is tat, it has gotta do with the total muscles relaxation that we unconsiously just let go (stage 1 sleep), but the brain mistaken it as a real thing tatz happening, therefore, jerking to keep our body upright, to prevent 'falling' as described? -

Yap! The characteristic jerk is known as myoclonic jerks.Originally posted by alfagal:hypnagogic jerks?
