physiology stuff

you dont have to continue reading, its nothing really of interest about my life...

I just got out of an anat/phys study thing and its boggling my mind, so I figured I would stop by the library and jot what I remember down so I can think about it again sometime once I more fully own the concepts. WARNING: this might not make sense the way I am writing it because I am not using proper terms and just getting thoughts out. and i am strange sometimes. I mean come on, i am a wise :)

We have action potentials occuring constantly through our body. [depolarization from gradients changing and reaching threshold to release different elements] These trigger voltage gated channels oppening and continuing down reaction style through muscles and nerves [mostly] These lead down cell membranes and continue with lots of different channels and nerotransmitters going through and they eventually go out of the nerve and with new parts added go down into t-tuberals and hit sarcolemas which release calcium to move our sacromeres closer together and our muscle contracts because of other details like a meyosin head being attracted to the active sites and then ATP cocking the head back down to be released again. And to the interesting part...haha ok well
our brain controls how many muscle fibers our motor units [a motor neruron and all the muscle cells it connects to] need to connect to which says how much strenght is used for an event. [example picking up a bowling ball] now our muscles exert to their full potential each time they are used but there are just different amounts and sizes of the fibers connected that are told to perform each task. Now applying this: we see a bowling ball and go to pick it up. our mind sends action potentials down our motor units telling certain fibers to fire in order to contract our muscles and pick up the ball. Knowing bowling balls to be on the heavy side we will be using more fibers connected to our motor neruons than if we pick up a sheet of paper. Now as we pick up this bowling ball, it is a trick one [extremely light] and because we already exherted so much strenght to the event our arm shoots up and the ball gets thrown up in the air. So I started thinking, can we trick our brains by telling them to use certain size or amounts of muscle fibers or are they learned already from experience, since we are little. Try to apply too much force to picking up the mouse, you catch yourself and stop it. so that wont work unless you fully devote yourself to it somehow without hesitation, but it would be cool to try and be able to control them. You kind of do that with like hitting a baseball you use as many as you can, but you already know to because of hitting one before.
Now even our thoughts are moved by action potentials, they are shooting through our brains to create the possibility of the thought we hadnt even thought yet. Then I realize that by exersizing we are expanding our motor neurons and fibers right? and keeping small ones too. BUT that means when we are working out to build our muscles we are actually also building our brains by controling the muscle possibilities. Do we use all possible fibers when we try our harderst? do we have to consiously think about it to do so?

OK now that most things are out of my head and I have not come full circle I'm going home....haha maybe one day ill look at this again and try to make sense of it all. Until then, I'll stick to what will be on the exam.

who knew? nothings new.

so not much has been going on lately... I went sledding in the mountains last week with our home teachers. umm I've just been busy with school a lot. I really like what I learn in anatomy but it is totally kicking my butt. I have decided today that I am going to use our free service at the university and get a tutor. Mission prep is fun, I cant wait till I get to put my papers in. Experimental Ed Adv Challenge is still my favorite class. I havent heard from Badger yet but should this week. I'm anxious about that. We went bowling for FHE today. Oh my gums and mouth in general are doing a LOT better. Emma and I bought matching twin shoes for each other for our half birthday, hers came last week and mine arent due here until wednesday which is extremely lame because I have had an outfit planned out to wear them with all week long. Tomorrow I'm going to lunch with Natalie from home and on friday Beth Hansen is doing a photo shoot thing with me for her senior project. she is taking pictures of people looking how their major stereotypes them and as themselves normaly. pretty cool idea. I miss ukraine a lot lately. I wrote a letter to mikki [my freshman year roommate on her mission in arizona] like 2 full pages about ukraine and my experience. I really liked being there. Im sort of just procrastinating my homework right now... I should get on that. It hasnt snowed in Rexburg for almost a week and in fact it rained a little today it was so warm! thats all for now. I cant really think of anything else...

Today is the day Derek is going into the MTC. I am so sad but excited, he already has his first letter written to me and most likely has sent it out by now. I cant wait to read it and finally get his address, haha what a guy. These past two weeks have been amazing. We've hung out almost everyday and have had so much fun. The next two years should fly by 'hopefully'. it makes it easier to know that i'm only waiting for about 6 months and the last 18 ill be active instead. We connect so well and writing each other is going to be so powerful for our relationship. I spent the past weekend down at his house in IF. His family is so much fun. Oldest of 5 boys so theres never a dull moment. And his mom is amazing, we are very similar. im not saying im amazing i didnt mean for it to sound like that but we had a blast together.

School is difficult but now i'm less distracted so that might help me out... go figure.
oh yeah and i got the most beautiful necklace from Derek for a pre-valentine's day gift. it has 6 perodots [sp?] increasing in size in a wave down on a gold chain. Its perfect.
i'm off to mission prep class, its snowing like crazy out today!

...mom requested pictures...

We have a new president!

This weekend has been so much fun! I have a lot of pictures to catch up on as Alexis has so kindly reminded me...

my roommates are awesome, we all get along really well and have a blast together, and the other one in the picture is our pet cat who appeared outside our door one day. honestly it scared the crap out of me, like it was going to suck my soul at night or something... we got rid of it though, traded for some yummy pumpkin cookies to these boys who have disposed of it properly [shooting it of course]

ok so we have Jessie- el salvador, Cheri- CA, Chari-CA, Alexis-CA, Emma-CA, and me-east coast represent!

ok my friend Alyson who I met in ukraine and is at school at UVU came up for the long weekend and we had tons of fun. We went snowmobiling with Derek and Kelly and some relatives... it was amazing. We went to the Palacades (sp?) and they were gorgeous! the actual riding is fun but having to steer and turn on those things i did not really enjoy, my muscles ached like crazy for the next couple of days.

oh and our machine overheated and wasn't running correctly but since Derek is a mechanic, he figured out what was wrong and was able to after a little while of fidgeting, figure out the problem and fix it. I learnt to drive and I did a good job until this one turn i didnt slow down enough and well despite dereks attempt to stablize the machine, we fell off got ran over and it ran off into the deep powder hit a tree and got stuck. It really was fun though. oh yeah and bri came too.

AND as a goodbye for now since I am on a roll, here is a lovely picture of Dad from christmas time... credit to leslie.

queen of the mountain

Well today up at Targhee it was GORGEOUS, the sun was shinning, and it wasnt too hot nor cold with a slight wind. Our teacher said its the best day all season. We could see out for miles of the mountains around and the flat valley below, amazing.

I signed up for level 4 and my one hour class has 7 of us. Two girls five guys. the other girl has only been up on the mnt four times ever. and she could keep up with us! mostly. The guys seem like fun, 4 of us stayed together for the rest of the day and hit everything, jumps, powder, tree paths, it was great. I am so worn out though, ill sleep so soundly tonight!

when I got home chari's friend was up here from utah so a bunch of her friends were all invited to craigos so i tagged along. There ended up being like 4 girls from Stafford VA, and they know oliver/ the johnston family. that was pretty exciting.

School has been good so far, lots of studying but fun. Alyson my buddy from ukraine is coming up this weekend so that should be tons of fun. We're going to go snowmachining on saturday which is going to be a blast. I cant wait!

school

I've only been out here for 3 days and I feel quite at home. Everything is going well, my classes are challengingly interesting and I enjoy all the hard work i've already put into them. I've been mainly focusing on my anat/phys class, i really hope i can keep up so it doesnt kick my butt- theres a lot of studying and memorization required.

My Exp Ed/Adv challenge class is going to be so much fun, we meet in a dance room so we have no chairs, a giant mirror and get to take off our shoes and socks each time. I already know a bunch of the other students from previous rec classes too... AND this one girl named Melissa that i know served her mission in Oaklahoma and totally knows cousin Caitlin! She was like you know sister wise? i said, I am sister wise, and yes that one is my cousin! haha it was great.

Mission prep is fun, the guy has a whole lot of energy and is funny but kind of insane at times, im used to that though ;) the class has way more girls than guys which is really funny AND a lot of them are just in it for an easy grade and not actually planning on serving, its not my business though so i wont complain. I like the class because we get to sing 2 hymns at the beginning of every class 1 is always called to serve but the other gets changed up.

Im not sure how developmental psych is going to be, it seems cool well at least the topic does... but we havent done much yet so i bet itll get better.

I am so excited for snowboarding! sara cabrera and i went to the meeting today and i ran into my old roommates from colonial house, Tosha and Rachel who are both snowboarding and are level 4 so we are taking the class together! cool.

at our apartment we dont have wireless :( and our plug in box thing is missing from our room so thats lame... but its ok too because i study a lot better in the library.

today Emma is moving into Mary Washington, i hope it goes well. I'm rooting for you em! actually im about to call you back on my way down to my place for a quick snack before more studying, LAME.

oh nine!

Well new years was pretty great, Emma and I went down to richmond and got to celebrate with basically all my virginia friends that i never get to see so that was nice. I made my resolutions back in ukraine durring october, posture and patience so i've been working on those for a while. It was nice to see so many people Ive hung out with over the years all together in the same general spot. its weird to think that its 09 alreayd, i mean i was supposed to be graduating college by 10 but according to my plans itll still be at leats 3 more years to get my bs degree but its all good, they will be very effective and benificial years. ive thought it was saturday all day today but soon it actually will be so i wont be thrown off anymore. oh! my friend travis wears suspenders just like me, we were sooo happy to both be wearing them. AND my friend daniel has picked up the harmonica too so we jammed some. I really like them all and am sad i rarely have time to see people since im always gone but im glad i enjoy the time i do get.
i feel i have completely adjusted to life here and that ukraine really is just a memory but now i will be leaving again in a couple days to head back out to school which will take another whole reality switch on me and i have to change to student mode again. it wont take much time at all though, i am generally good at adapting.
