eating lab

This lab was excellent. In a procedure, Leeann had Seth and I attach some muscel reactive  adhesive sticky things (I honestly do not remember what they are called). These little stickies were attached to two points on our jaw and another to a different point on our body (both Seth and I opted for a pulse point). Seth went first and ate a different variety of foods and drank a large gatorade. With the data Seth gave us, it seems like he does not use a lot of energy to chew anything. He averaged around a .788 energy even used to eat his items.

I on the other hand seemed to use a a extream amount of energy for little things. an average of .865. I did have a jaw ache though so that may have factored into it. Out of the both of us, we both averaged a .827. We learned that it varies on the individual on how much jaw power you need to eat. We also learned that peanut butter makes me act like a dog with peanut butter stuck to the top of its mouth. Apparently it was amusing.

Bones bones---and bone breaks --\--

Well I should know a lot about bones. I think my family holds the record of the most broken bones in a life time.

My father has managed to crack his skull, break his ankles, and have a compound fracture all in 25 shorts years of his early life. Just those years! I have managed to disable every single bone in my body, break my fingers and half of my toes. My mom has busted her own ankle. My brother has also broken his nose. Now tell me that is not a record?!

Most of our fractures were hairline.
such as this. It was barley noticeable in the X-rays and not much could be done. It was excruciating pain.
Now the next fracture is what I had with my big and pinky toe on my left foot.
yet I have also had a stress fracture on my foot as well. I had jumped at the same time as a soccer player and my toes collided with his cleats. It was enough stress to bend my toe back and create and compound fracture.

Now with my pinky...it was a complete fracture. When I mean complete, I mean like the bone snapped and now my poor pinky is crooked. The thinner bone snapped , and was moved to the side. I never went to the doctors to fix it. I was after all in the middle of a great freshman season of basketball and I was sure I can finish the season with some tape and gauze protecting my hand. It made it worse really.

just like this. The bone continued to repair itself and the calcium build up has left my pinky crooked and a slight calcium deposit giving my joint a rough rounded appearance.
Now my dad's injuries were more...extensive and slightly funny at his own expense. (sorry dad!)

This is probably the most common injury both me and my father have sustained.
you guessed it. Skull fracture. See both me and my father have sustained blunt force trauma to the head multiple times. IE basketball accident, football accident, just falling on cememnt. Everything to manage a head injury, we have probably done it.

Examples of reciving said skull fractures through blunt force trauma....
case number one: This shall be my story. It was during a basketball season my freshman year. Simple request from my coach ("Get me the *bleep* ball Wolf! <---- that was my given name in the season)  and I was chasing down a 200 lbs. girl from Karval. Long story short: I caught her, my own teammate used me and her as a stop wall i crack my head on the only patch of cement in the gym with ove 300lbs on me.

case 2: now imagine that with my dad. Full football gear without helment messing around with friends. Yea not so pretty.

Now on to the fun part.

Compound fractures. Thank goodness but unforunatley my father has. It was at his elbow joint. His elbow broke falling out of a cherry tree. Originally he and his sister thought it was a stick that was sticking out of his arm but it actually turned out to be a long bone. He would not have survived if his grandmother had not inserted her finger into the gaping wound and cut off the blood flow from his artery.

just at the elbow.

Now on to actual bones. It might explain more about fractures if I do this right.

THere is several different shapes of bones.
long, short, flat, and irregular.

Indside the bone is where a lot of the body magic happens.
We have compact bone which has no poruous lok about it at all. It is solid bone. Spongey bone is not yet mature bone that has tiny holes in it making it look like sponge. This is a classic example of the long bone in our bodies.

integumentary system

The integumentary system in our bodies is...wait for it.....our skin!

Yes the skin on your body is the integumentary system. It protects our bodies from the outside world. The air, the bugs in the world, and even the sun.

The epidermis is the top layer. It is completely dead skin. The skin is like a onion. It has many layers. Each layer rises and the dead skin is the top layer that is rubbed off. Interesting/ disturbing fact that I learned was you would have to wash your bed sheets everyday to get rid of the skin flakes that are rubbed off in your sleep.

Now the major layer in your integumentary system is the dermis. It holds major functions such as the the sweat glands and nerve endings. Also within this layer, are the capillaries. Another interesting fact is, when you lay in the sun (if fair skin you can see it the best) and you feel your skin heat up, it is your skin releasing the heat. The capillaries have expanded, making your skin seem red and is releasing the heat that is stored in your skin. It is acting as a refrigerator.

Now onto the fun part of this post. Skin diseases ....

Not all of them are dangerous but there are some that are life threatening. Such as... the bubonic plague (more commonly known as the black plague).
Which is caused by these little buggers
 Which ride on these guys
Who stow away on boats and the flea jumps to people. Thus transferring the bacterial infection which caused painful swelling of the lymph nodes in your system and making them burst open from the overload of puss and blood. There are three types of the "plague". Not all of them have the swelling though so be careful.

Tissue engineering review

Tissue Engineering

Summary:


The new development of bio genetic growing of tissue cells is now upon us. With the help of genetically altered rats, NASA, and the fore fathers of cell/tissue growth (Dr. Joseph Vacanti and Bob Langer). Tissue engineering is the basis for helping people who are needing to replace a organ or other features such as cardiac tissue, veins, cartilage, and skin. Thus it makes it easier for people who have a difficult time receiving help for a transplant. Way easier. The transplant actually works as well, even though it can be grown from a live specimen or even in NASA no-space container.


Weird example:
Photo  of heart valve





See! It's one of the genetically altered rats that is growing a ear for a person.... please don't shudder like I did.








Opinion:


*shudder fit*


Ok that is out of the way. See this is a new advancement from the past ( this all started in 1987). Now people don't have to be on the airing list for long anymore and people can also be treated for life threading illnesses like bone marrow transplants and cartilage transplants.

Histology

Histology: The study of the form of structures seen under the microscope. Also called microscopic anatomy, as opposed to gross anatomy which involves structures that can be observed with the naked eye. Traditionally, both gross anatomy and histology (microscopic anatomy) have been studied in the first year of medical school in the U.S. The word "anatomy" comes from the Greek ana- meaning up or through + tome meaning a cutting. Anatomy was once a "cutting up" because the structure of the body was originally learned through dissecting it, cutting it up. The word "histology" came from the Greek "histo-" meaning tissue + "logos", treatise. Histology was a treatise about the tissues of the body and the cells thereof.
Histology

I have studied cranial, epithelial,skeletal, and bone slides. Each were very different. In the lab we did, we were tought how to use a microscope and studied the afore mentioned slides under a 10x focus and then a 40x focus. we were told to draw and identify each slide. We did this and I shall post a good quality picture soon.

Epithelial:
  This is just one example of epithelial tissue. It can also com in squamous, columnar, and pseudo-.

Cranial: is well from your head. It can also come in cuboidal, squamous, columnar, and pseudo-. There are no real good pictures I could find. Sorry.

Bone:
Here are two really good pictures (one of which I stared at under a microscope which was extreamley amazing). This is bone tissue. You can tell it is by the circular pattern in the second picture.

 This will also fall under the skeletal tissue catagory.

Anyways. I was also doing a lab with Cassy, and Jena. We learned how to use the microscope exceedingly well. Focusing was a cinch for us and we all took turns drawing what we saw. Unfortunately Jenna threw our drawings away because they could not be transferred to the computer well. This was a interesting lab, we had to guess at what we saw. Almost like a test to ourselves. And we had fun for this lab which made it worthwhile. Though we could not spell or pronounce any names we learned each slide slowly and it was worthwhile. I would like to thank Mr. Ludwig for that.

please forgive the spelling mistakes spell check broke on me

anatomy rap rap

No this is not a rap. Sorry I had started this out as being daring but then I decided to play it safe.


Superior and inferior

Anterior and posterior
 Medial, lateral, and intermediate 

 Proximal and distal
Superficial and deep 


Superior and Inferior


Superior = Cranial so you are talking about your upper body. Superior because this is where the most important functions of your body are.


Inferior =caudal, so you are talking about your lower body away from your brain. Not many extremely important functions are done in the inferior portion of your body.


Anterior and posterior


Anterior= the front of your body.  (ventral) A good example is your breastbone that is anterior to the spinal cord.


Prosterior= Behind your body. (Dorsal) The exact opposite of anterior.


Medial, lateral, and intermediate 


Medial= as the name suggest, medial means toward the middle, such as your heart. It is near the middle of in-between your arms.


Lateral= I actually didn't know what this one meant. This one means away from your midline. Such as you stretch out your arms and that is a lateral position from your heart.


Intermediate= I always thought this was in-between the middle and the outside. Which sums up this position term. It is a in-between  place of a lateral and medial position.




 Proximal and distal


Proximal= is closer to the origin of the body part you start at. 


Distal= is farther from the origin of the body part as which you start.


Superficial and deep 


I know both of these well.


Superficial= shallow. you can see it on the surface. A superficial cut is a paper cut. Hardly bleeds and you can see the damage on top of your epidermal layer.




Deep= deep is well...deep. You can't see the whole cut as it goes into many layers of your epidermis and you can't always contain the bleeding and such. 



Will add more

Homeostasis

I could act like I am high and mighty know it all bout homeostasis but alas I am not. Negative feed back I can get from my own body. It is a constant thing we investigate in cross country. In fact we check before and after every run. Our heartbeat/heart rate. Now if I could show you a little video I Would but I don't have one. Darn! Anyways, here is an example.

Day something something. Activity: el diablo (coughcoachcough)
Total: 20 some odd kids, 1 extremely sick, 5 injured and 14 healthy

Heart rate for the team average 90 beats per minute at the beginning, without the adrenaline rush. 120 for the sick kid.

At the end of the run the team average a 150/160 per minute beat. 180 for the sick kid. Now you can honestly agree that the sick kid was having negative feed back working in her body to get it back to normal. It didn't happen. Said girl went out of school, for nearly five days. Have you guessed? That sick kid was me.

homeostasis in any body is all the chemicals and functions in said body, weather it be healthy or not, working together to create a common balance. In other words, if you feel good that means you are in a state of homeostasis. If you don't feel good, like the sick girl (me), then your body is working to put itself back into homeostasis.
