The Human Body and its Responses

[xXru1n3dXx]

 

 

 

I had to do some homework on sleep in science. Here is part of what I got:

REM sleep after several experiments is believed to be memory maintenance, where knowledge is either discarded or stored after being reviewed (by the brain). This theory leads us to believe sleep is required for learning and memory.

 

 

 

then why do people seem to forget so many things that they needed to remember the day before when they wake up?

 

Laziness, not enough efficient study (studying for 5 mins won't get you anywhere), sleep deprivation which leads to no REM sleep.

 

I just found that theory interesting, we only had to evaluate/list key points of a website our teacher emailed us, so don't take it as absolute fact.

Every time I think about some really physically painful things, I feel that pain again. Like, when I think of the time I broke my rib, it hurts. :P Or when I fell of my bike when I was five and skinned my knee.

 

 

 

Also, I find it really easy to recall the way things or people smell. :P

Known fact : males always wake up with morning wood.

 

 

 

Oiiiiiii, why is that, does anyone know. Is prime time for sex in the morning, or do we dream about sex all night long? :-k

 

 

 

How about when you're almost asleep, and you're kinda having a dream. One of the ones and you might be falling off a cliff, and sorta do a big jump in your bed, I really hate those. :x

 

 

 

I noticed a lot of those things over time

 

 

 

When i need to go to the bathroom, the time i need to go the most is IN the bathroom. Thats when its unbearable. Or if i don't really have to go, being in the bathroom increases my need to

 

But when it is really unbearable is not just in the bathroom itself, but standing in front of the toilet.

 

 

 

Worst thing I have ever done in ways of sore bladder is play the game of 100 shots of beer in 100 minutes. Works out to be around 12 bottles of beer, and you're not supposed to go to the toilet until you've finished the 100 shots. From the couch to the toilet = pure torture because it all rushes down once you stand up.

How about when you're almost asleep, and you're kinda having a dream. One of the ones and you might be falling off a cliff, and sorta do a big jump in your bed, I really hate those. Mad

 

 

 

 

 

that happens to me to! like ill be thinking about basketball while about to fall asleep and then i think of a basketball coming at me and i jump and wake right up.

 

 

 

One time i was studying on my bed and my head was against the wall and i started to doze off. then a football was coming at me in my half asleep so i jumped and got a bump on my head from hitting the wall.

Known fact : males always wake up with morning wood.

 

 

 

:lol: We know that.

 

 

 

To stop you peeing in the bed :o

 

Seriously.

 

 

 

well you learn something new every day I guess, but WAIT, I don't know how true that is, why do some boys (Even like 11-14) still pee the bed frequently? :-s

 

 

 

 

 

Want to know why some poop floats? trapped fart bubbles.

[johntm]

 

How about when you go home and you was told that you was going to be eating tacos. Your like "YES!".. and strangely, your stomach feels "ready" for tacos. However, when you learn your gonna have something that you dislike, all of a sudden your like.. but I was ALL READY for tacos! Yet you never seen any of this food.

 

 

 

 

I hate you so much right now. I am home alone, with mac n cheese, and you mention the one thing I desire right now.

 

 

 

You know what I always wondered? Why do we need sleep? I understand it "Recharges" us, but why does just sitting down or laying down not help?

 

Yea seriously, cant we just jump in the fountain in the heroes guild and be recharged like our glories? Too much rs, maybe?nah

[johntm]

Our brains are the most complicated things in the universe... :-s :shock: especially girls :-$ :lol:

 

 

 

actually, women are :?

[IGoddessI]

Okay it's taken me long enough to get back to this thread and ramble a few useless facts:

 

 

 

The Human Body and its Responses...Hmm

 

 

 

Infant development:

 

 

 

Rooting reflex: A touch on the cheek induces the infant to move its mouth forward to the source of the touch (helps to guide feeding).

 

 

 

Sucking reflex: Tactile stimulation of the mouth produces rhythmic sucking.

 

 

 

Orienting reflex - The tendency to pay greater attention to novel stimuli than to familiar stimuli. Longer fixation times occur with novel stimuli.

 

 

 

(Brain waves differ between novel and familiar stimuli)

 

 

 

They use relative attention paid to an object to gauge infant's discrimination between objects.

 

 

 

Infant amnesia - lack of explicit memory, but evidence of implicit memories (i.e the movement and the consequences)...

 

 

 

For example.. If I move my arm out a certain way it's a consequence.

 

 

 

Everything goes in to a childÃÆââââ¬Å¡Ã¬Ã¢ââ¬Å¾Ã¢s mouth that's why we don't remember until we learn hands on.

 

 

 

Attachment: Harlow (1959) conducted an experiment where 2 infant monkeys were observed. Two model mothers were built. One model mother was covered in warm cloth, the other of steel but with a food source. Regardless of the food source, the infant monkeys still preferred the mother who was warm and made them feel secure.

 

 

 

A secure attachment: Child welcomes the mothers return and seeks closeness to her.

 

 

 

An avoidant attachment: Child ignored the mother

 

 

 

Ambivalent attachment: Child exhibits anger at the mother while seeking to be close to her.

 

 

 

Disorganised attachment: Child may approach mother but gaze away, and may show odd motor behaviour and dazed facial expressions.

 

 

 

(This also depends on child's biological response to distress and maternal responsiveness)

 

 

 

The more favourable parenting style is Authoritative because it enforces standards, but encourages verbal give-and-take.

 

 

 

----

 

 

 

Classical conditioning - Associating a neutral stimulus with a stimulus that leads to a reflexive response.

 

 

 

Some of you may have heard of PavlovÃÆââââ¬Å¡Ã¬Ã¢ââ¬Å¾Ã¢s theory where he would present meat (unconditioned stimuli), which made his dog salivate (unconditioned response). He then rung a bell (conditioned stimulus) which the dog learnt over time that he was about to receive the meat, causing him to again salivate (conditioned response).

 

 

 

This is how it works... I listen to music every time I go to work, school, and study or to the gym. I now associate hard work with music. When I want to achieve something that involves hard work... I listen to music.

 

 

 

Another example is little Albert who was 3. Little Albert was a young boy whom we let play with a little white rat. Albert and the little white rat became friends. After a while of playing with the rat, a loud gong noise was made. Little Albert was startled but with time continued to the white rat. Once again a loud gong sound was made and little Albert started to cry. He didn't want to be friends with the white rat anymore because he knew that when he played with him, he would get scared. Unfortunately this also led young Albert to be scared of other white furry objects such as Santa clause's beard and cute bunny rabbits.

 

 

 

It's the same when you think of a Big Mac (unconditioned stimulus) it causes you to salivate (unconditioned response). So when you're next driving in the car and you see the golden arches of Mc Donalds (conditioned stimulus) it also makes you salivate (conditioned response) as it makes you think of the big mac.

 

 

 

I'll write more when I get back need to hurry off somewhere...

[fakeitormakeit]

The human body is truely a great and complex work of art.

 

It is truthly amazing if you think about it. The ability to heal ones self, create sounds in your mind without them actually having to be phyiscally real, dream and vision things that you don't have to have seen. Invite new and very useful technology to ease the day to day tasks.

 

 

 

The list goes on, we are quite remarkable really.

 

 

 

edit: 600th post, yay

[trapical]

Hmm, I suppose I should contribute something to this tread being the Bio major and all... :-k Ah ha! Spiffy little fact I came across. Okay guys, hang with me, this is actaully pretty interesting but you are going to need a little bit of background knowledge about the different types of nerves works. Prepare for a 45 second crash course on how nerves can work \

 

A nerve picks up a signal at one end and then does a complicated process, I won't get into, then sends the signal out the other end onto the next nerve. However what sends the signal out the end to the next nerve? Well it can be two things. Either:

 

 

 

1)Neuro transmitter chemicals like acetylcholine, these chemicals are released by the cell into the synapse between the cells, and the molecules wander around the open space until the land by chance on the next cell. This method is pretty simple and sort of slow compared to most other body functions (it still happens in 1/100 of a second, but it is by far the slowest part of your nervous system, it's takes up about 99% of time it takes for a nerve to send a signal) But there is another way...

 

 

 

2. Electrical synapse. I'm sure you have all seen the movies where they show the brain and lightning is shooting across everywhere. Yes, these are the "cr̮̬̉̉me de la cr̮̬̉̉me" of cells. These cells are able to create enough charge to shoot mini lighting bolts over to the next cell instead of using those silly neuro transmitters.

 

 

 

Okay so let's review. A nerve cell can either use chemicals (neurotransmitters) or electricity when dealing with passing the nerve signal to the next nerve. The advantages of electrical nerves? Well it's instantaneous, it increases the speed of transmission by almost a hundred fold. Also remember that neurotransmitters are complex chemicals, and a cell only stores so many at once. Meaning neurotransmitter cells can only send a signal so many times before they get tired and need to "recharge". This is one of the reasons why your muscles get tired, the muscles cells are running out of these neurotransmitters and need time to make more.

 

 

 

Some cells can't afford this problem, cells they need to work 24/7. The heart for example, is made entirely of electrical synapse cells so it can run nonstop as long as it has food. Every second the lightning bolts are send across one heart to the other, every second of your entire life.

 

 

 

In addition to heart cells brain cells connected to your conscious self are also electrical, since they need to work without rest. So heart and conscious = electrical, but what about all your other nerves? Well Different people have a different mix of electrical and chemical synapse nerves. What does this mean? Remember electrical nerves have two bonuses, the first being fatigue (which isn't that big of a deal) but the second is Speed. Remember how slow chemical neurotransmitters work? Yea, well, electric ones are instantaneous.

 

 

 

People with even 1% more electrical nerves have substantially better reflexes than the people that don't. Now know what's interesting? Biological historians have traced the bloodlines of famous swordsmen and found that the decedents of people such as Miyamoto Musashi and did tests to determine that these people have extraordinarily high electrical synapse ratios. When most people have 8-12% these people had around 20-30%. The family joked that their grandparents always bragged about being able to do things like catch training spears mid flight and other feats that required incredible reflexes and speed.

 

There are theories that they was a tribe of humans thousands of years ago that evolved through some event and they all had 100% electrical synapse nerves. There people would have been demi-gods in any form or combat or physical skill, they would not fatigue and they would have reflexes faster than you can even image. You probably think you have pretty fast reflexes, well these people would have had reflexes approximately 90,000 times faster than anyone alive today :ohnoes:.

 

 

 

No one knows what happened to these people, but their genes have been spread out across the globe. People such as Alexander the Great, Genghis Khan, or "King Arthur" all probably possessed a higher concentration of these genes.

 

 

 

Even today, some of us have these genes and some of us don't. Do you win a lot at games like "bloody knuckles"? Do you have fast reflexes? Well chances are one of us at this forum is part of this ancient bloodline and has a higher electrical synapse count... :-s

I think it's weird when you see someone get hurt and the part they hurt starts to hurt on your body. Like you see someone's toenail get ripped off (Or think about it) and your toe hurts.

[trapical]

This is actually a testament to how crude of brain is. Sure it's complex but if you think about a toenail getting ripped of the part of your brain that deals with pain is like

 

"Wait! What?!! Toenail ripped off? Where? Uh, uh, uh, umm, crap why isn't it confirming?! Did the brain get the image of a toenail getting ripped off, let me double check.... yes it did! But why isn't it going in the normal channels?! Ah crap, lets just go on standby to alert the conscious in case something really is going on *ENGAGE SLIGHT PAIN TWITCH OF TOE*. "

[Rebdragon]

o-O

 

Dang, I thought you were going to bore us with the [simple :-w ] process of neurons, but that's pretty interesting. So now I know why someone can have faster reflexes, and now I understand why EKG's are useful :lol: >_<.

 

 

 

I'd like to say I have fast reflexes (mine are the fastest in my family, but I'm the closest to my prime at 17, so I have an unfair advantage physically), but I'm sure everyone thinks they have fast reflexes, just like how everyone thinks they own at combat until they get into a fight :-w .

Why do some boys (Even like 11-14) still pee the bed frequently? :-s

 

 

 

 

It's not just boys. My sister is 14 and my other one is 11 and they still wet the bed. I think it has something to do with weak tissue in the bladder. I wet the bed until like 5th grade. I should go look it up, actually. All I know is that it is genetic in our family. My grandma did it, my mom and all her siblings did it, all my siblings did/are doing it. You just have to outgrow it.

 

 

 

Plus, morning wood does not sop you from wetting the bed. Just makes you pee in your face ;)

Lol, nice try but you are both wrong technically. For one, it's biologically impossible to pee with an actual erection, so there's no peeing in the face side effect :wink:

 

 

 

However saying men have 'morning wood' to prevent bed accidents is just silly. What about females then? No form of sexual stimulation can prevent a women from urinating. So do all females wet the bed every night since they can't get a urine blocking morning wood?

[Lionheart_0]

:o Very interesting. I would love to hear more form Goddess and Trapical.

How come I can pee when I have one? It's really hard because it sprays upwards, but I still do it.

Well this conversation isn't awkward at all, but anyway, if your peeing you don't have a full erection. If you have one and you try to pee your body than backs off the erection a little bit, thus allowing you to pee.

 

 

 

Wow, I really need to get used to these awkward conversations if I want to become a doctor...

I never said girls didn't pee their bed. but yeah, I knew that the erection thing was wrong. ERECTION!

Hahaha, that was classic. No shame at all!

[flying_death_bombs55]

whenever I see gory things I immediately feel like my limbs are going to be ripped off.(yes Im wierd)

[Soul_failure]

When i see something i don't like my fingertips hurt (this makes me feel sick), and i sometimes get this feeling that all my veins are going to be ripped out lol... i will stop now before i am carted off in a funny jacket. :shock:

[TheMaruder1]

Heh, you guys completely reminded me of a Robot Chicken sketch with this topic, :lol: It's funny because it's stupid.

[Bludragon124]

Known fact : males always wake up with morning wood.

 

 

 

:lol: We know that.

 

 

 

 

 

Yeah... :oops:

 

 

 

Well, the big thing my body does is it associates how I feel with different things.

 

 

 

For example, I went to a store to buy a card game (I don't remember what it was), and I got a headache. I played it with my brother while I had a bad headache, and when I tried to play it again the following day, I got a headache.

 

 

 

That's why I can't eat ramen noodles anymore too, pretty much the same thing happened, except I threw them up... now they sicken me.
