desperate ways to help remember different parts of eye.. that is.. to have a dramatic monologue.. (think emily of emerald hill -- stella kon.. gwahaha.. sec two langarts.. hohoho)

Epicarp, Mesocarp, Endocarp, lend me your nerves..
we have gathered today.. to memorise the eye.. not disect it..

TearGland secretes tears to lubricate the conjunctiva (when eyeballs move to reduce friction so they wont quarrel) and wash dust particles away.
Sure he is noble.

Eyelid wipes dust particles off the eyeball, spreads tears over eyeball, shields eyeball from excessive light.
Sure he is noble.

Eyelashes shield the eye from dust particles.
Sure he is noble.

Sclera/ Sclerotic coat (tough, white fibrous coat-- sounds oddly like coconut, which brings us to the point of endosperm and pericarp) forms a protective layer around the eyeball. it continues as the transparent cornea in front of the eye. (sounds like a double agent.. maybe kira will be interested)
Sure he is noble.

Rectus muscle is used to rotate the eyeball. It aids people with great attitude and their eye rolling habits..
Sure it is noble.

Conjunctiva (thin transparent part covering the exposed part of the eye) protects the eye.
Sure it is noble.

Cornea allows light to enter the eye (so eye needs to breathe too.. actually so do i. breathing can or can not be controlled by the brain.. subconscious breathing involves the cerebrum) thats why we cant sleep with contact lenses because it deprives cornea of oxygen and thus increase risk of eye infection.. It has a denser medium than air and is the first place where light is refracted.
Sure it is noble.

Choroid coat contains network of blood capillaries that nourishes the eye. It is pigmented black to prevent internal reflection of light.
Sure it is noble.

Ciliary body is the modified end of choroid. It alters the thickness of the lens by contracting or relaxing.
Sure it is noble.

Suspensory ligaments attach lens to cillary body.
Sure it is noble.

Iris is the modified end of choroid (same as cillary body). It is circular disc shape. It has a pupil (no.. it is not a teacher) in the centre. Iris has circular and radial muscles to control size of pupil.. (control freak.. gah)
Sure it is noble.

Lens (transparent, biconcave, crystalline)- changes in its curve alters length of focus to so there images on retina will be clear
Sure it is noble.

Retina is the light sensitve area containing photoreceptors (rods and cones)
Sure it is noble.

Photorecptors are connected to the nerve endings from optic nerves
Sure it is noble.

Fovea centralis is part of retina where images are normally focused. Only contains cones (for colour vision)
Sure it is noble.

Aqueous humour (watery fluid) keeps eyeball firm and refract light

Vitreous humour (transparent jelly like fluid) keeps eyeball firm and refract light

from the same layer:

-sclera, cornea
-chloroid, cillary body (modified end of chloroid), iris (modified end of chloroid)

PHOTORECEPTORS: rods and cones

RODS- for vision in dim light
-contains rhodopsin
-rhodopsin (pigment) is bleached in bright light
-needs vitamin A to form

CONES- for colour vision and vision in bright light
-less sensitive to light
-inefficient in dim light
*red
*blue
*green
each have different pigments
allows one to see a SPECTRUM OF COLOURS

dim light
circular muscles relax
radial muscles contract
causes pupil to dilate
-let more light into eye

bright light
circular muscles contract
radial muscles relax
pupil constricts
-let less light into eye

DISTANT
circular ciliary muscle relaxs
radial ciliary muscle contracts
suspensory ligaments becomes taut
-lens becomes flattened
allows light rays to be focused onto the retina

NEAR
circular ciliary muscle contracts
radial ciliary muscle relaxs
suspensory ligaments become slack
-lens become rounder
allows light rays to be focused onto the retina

binocular and stereoscopic vision
advantages of two eyes:
-larger field of vision
-defect in one eye will not result in complete blindness

-each eye looks from different perspective
-visual centre in brain combins both to give three dimensional image
-allows distance to be judged acurately.

this week is a crazy crazy week.

today is grandma's birthday =) lets rewind back the days..

yesterday. syf- such a queer feeling. just want to say.

NYJF did a great job =) shant go into mushy details. hah.

mm props was hard at first. being new at this.. had totally no idea to what i am supposed to do. thank God for Uncle Jack and Uncle Chng 's wood 'candles'.. kamsa to Uncle Chng..helped so much here and there e.g helping me open the can of paint -.-'' and thanks to those who wished NYJF luck =) there are always many people and things that we wish to thank .. but we can never finish listing all of them..

and very thankful to those juniors who turned up to help daoju meetings here and there =) and even the lovely sec ones who helped to stick the fake money together at backstage that day during reharsal.. really happy and heartening to see such enthusiastic juniors =) kamsahamneeda!

yea it was tiring (and lonely.. gah) to paint pillars by the staircase near the library for hours.. gah.. heyhey but come to think of it.. isnt it just cool? :D to think i used to pon some of the daoju meetings last year during xyxy.. tsktsk.. and i personally will never forget all the fake (and stupid..erps) money and letters for 'xiaowen' .. seriously.. perhaps should keep some of these to remind myself of my secondary school drama days..

when the pillars were done.. there were reharsals at the audi.. really touching to watch the play.. jiulin and linlin acted really well.. good acting skills that will trigger tears from the audience =)

hmm.. i m talking about all these because i m actually rather nervous for the results.. yea i agree it doesnt really matter and that we cant do much now. .but seriously.. arent U excited too? :D arrgh..

but because of syf.. didnt manage to go tya yesterday.. owes the kids pressies for consecutively five weeks now.. opps!! D: church just now was enlightening.. its really encouraging to know that God never leaves us and there is always hope. When we fail, it doesnt mean that we are lousy or something. its just that God has a better plan for us. When there is hope, there is life.. just to share something that i learnt today.. =) always believe that He is in control and everything will turn out fine =)

mm.. the this week has been hectic and hard.. falling sick.. pia-ing for tests.. listening to stuff that i dont want to listen.. geog competition cum pres..staying back for syf.. on wednesday i was at my breaking point already. having a super horrible flu.. woke up on thursday with a very.very.very. blocked nose and peeling skin.. dang.. but everything is fine now =) i am very.very.very. much happier =) mm and thanks esp to people like cynth beaniemam sophh cypoker banana etc etc who put up with my wild moodswings for the past few days due to my stupid flu, lack of sleep and pent up stress. haha..

oh and actually the teachers are really great too.. jilaoshi who is always so understanding towards our class and not scold us when we accidentally succumb to fatigue and doze off during chinese lessons.. lilaoshi (li2 lao3 XD ) who helped us move the two big fat candles up the five stories despite wearing high heels herself.. its really through tough times we see her kindness.. etc.. haha..

things are getting much better now with mr. khong taking over for geog.. no hard feelings.. but really.. learnt more last week than the rest of the term -.-'' geog competition cum pres went quite all right.. though we are sure it is impossible to win the ten thousand cash prize plus a trip to switz.. but glad we didnt screw up that much.. and the judges were sweet people.. gave really good comments about tcm..

gah.. i dont wish to sound like i m giving some speech for star awards.. but really.. life couldnt get better =)

just something random to my mitosis daughter in case she is reading this,

mitosis means:
Mitosis is the process by which a cell duplicates its genetic information (DNA), in order to generate two, identical, daughter cells.

your mummy is clever :D and not to mention.. a little crazy now..

haha.. i am so happy.. lalalalala..

many tests next week.. jiayou!

woa mummy's (real) birthday soon.. shall start saving up and practice guitar so that i can play her a nice and in tuned birthday song comes that day =)












lalalalalalala..dududududu..
something random.. we are just passerbys of the world..

chirpy mood.

sorted thoughts out.

live my 0wn life, that is.

anyway, found joy in maths.

lets solve them like Light and L.

go figure. go figure. go figure. go figure.

children's club today was fun. had great fun with kids. wanying insists that i am a 'noob'.. i actually lost badminton to a six year old boy.. oh dear.

saomu-ing tomorrow. sweep the tomb.. owells.. not many tombs left in singapore.

eton.htead <3
L.thgiL.raeN.olleM.asiM.


wheeheehee.. finally finished painting the two pillars for props. hopefully it does not rain on syf day or the words are going to disintegrate right on the spot. paper will still be paper..

owells.. maybe if they really do dist-INTEGRATE... i can try to DIFFERENTIATE them..

hope we'll do well =)

dear pollutants,

please leave me out of your whatever, whatever, whatever plans to take over the universe.

sounds harsh.

the way people twist the facts to their own benefit is simply disgusting

they do it again and again and again..

silence does not mean consent.

it does not mean anything

for i do not want to step my foot into your polluted puddle of politics.

i must remember.
busybusybusy. lots and lots of commitments for the following months.

-tya everyweek
-yfc
-gradnite
-and i suppose theres hfy

music is the best best best.
i m hooked onto jaychou' songs.. like ju hua tai, feng, qing tian etc. haha currypoker should be happy.

heard keane's 'everybody's changing' on mtv channel just now while eating supper. hah. er yea everyone change a little everyday. technically. for better or for worse it is what that matters.

goodnight. or rather good morning!

i want to ruuuuuuuuuuuuuuuun!

finally.i have time to consolidate the week-long thoughts that has been in my head since the fateful incident of my stolen bag last saturday.

really.it is rather amusing to watch the teacher's expression change from sceptism to sympathy when i showed them the police report explaining why i couldnt hand in my __ because it was stolen along with the bag.

come to think of it, there were a lot more things in the bag than i thought. well. lesson learnt. not to leave things lying around. and really. be thankful for what i have now because it is really a whole load of trouble more than what my head can take to lose them.

unlucky. who can be more unlucky than me? but who can be more unlucky than who? what is luck then? i guess its hard to phantom. things happen for a reason.

forgiveness. i heard this story and was touched.

there was this little boy who was asked to look after his brother during a camp. however, his brother was extremely mischiveous and caused him a lot of trouble. finally, he got so angry that the decided not to fogive is brother and said:
'if i forgive him again, i am a 大笨蛋!'
then the camp leader asked him:
' Jesus forgave all of us.. is he a 大大大笨蛋 then?'
the boy forgave his brother.

just some musings.

come to think of it. i have forgotten about my julius caesar work.
after writing all these down.. i do feel a little better. hah.

more work.
Geog SIA. Props. LA SIA. TYA easter proposal. YouthforCauses proposal.

hehe..but yanne etc have been doing most of the work for tya proposal and youthforcauses proposal lar.. kamsa! yea.. thanks ppl for being so thoughful. ppl like soph and cynth who did the final pia-ing for geog sia when i went to tya. kamsa! i will makeup de.
