Chewing Lab!!!! NUM NUM NUM!!!!

Hypothesis:

Logan and I hypothesized that when we both consumed or ate the same foods our mV per second maybe different not by much but still noticeably different. We assumed this because our height and bodies are total opposites. So with that we figured that my rate of this chewing lab would be greater then hers. More mass would equal higher rate of chewing compared to the other.

Materials:
-Logger Pro
-Electrode -Tabs
-Different Foods

Experiment:
In our experiment we first placed the electrode tabs on the upper and lower parts of one of our jaws and also one tab on the inside of our wrist. We hood the clips to the tabs that read into the computer program and then began testing our experiment. We began by simply recording the resting period with clenching of the jaw. From there we moved on testing different kinds of foods for about 30 to 45 seconds. Each food had a different rate and amount of time it took to chew thus proving that our jaw works harder with some foods and easier with others.

Results:
So after all the recording and chewing we had our results. And we seen that to a point we did prove our hypothesis right as for the fact that every food that Logan and I ate her rate was lower then my own. So therefor proving our hypothesis correct that overall some people chew harder or faster then others.

Bones... What are they called???

Bones, Bones, Bones!!!

In non-displaced fractures the bone ends after the fracture occurs still retain their normal position in the way they originated from.
Example:

However in displaced fractures the bone ends tend to be out of their normal position or alignment.
Example:

One of the most common fractures is a compound (open) fracture, where the break is clearly visible as it penetrates through the skin.
Example:

In a simple fracture (closed) the break is still apparent, but it does not penetrate through the skin
Example:

Complete fractures are when the bone is broken all the way through the bone
Example:

Incomplete fractures do not go all the way through the bone, almost as if it splinters the bone
Example:

Linear fractures are breaks that are parrallel to the longer axis of the bone
Example:

Whereas a transverse fracture breaks perpendicular to the bone's long axis
Example:

Bone BREAKS!!!

Self Analysis

Hello!!! Welcome to my Anatomy Self Analysis!!!!!! =)
     It's incredible how fast the first quarter has passed by and I have learned so much regarding histology, tissues, homeostasis, the organization of the body, and much more. After sitting through slides and slides of notes, I think that it has really paid off when it comes to my understanding of all the various topics we have discussed. In the beginning I struggled to post blogs about the concepts I was understanding, however now I have become a PRO! I finally understand when and how to post my learning's in order to show you what a great teacher you are and what a great learner I am! The feedback that you provide us with is one attribute that I really do enjoy because it gives me a better understanding on what I should work on or fix. I've found that although I struggled with homeostasis a lot, I now have a good concept of what it is all about. I now am able to tell when something is showing a positive or negative feedback, and I can easily discuss how homeostasis works and some of the side-effects it causes, such as sweating and shivering.
Although I have become pretty familiar with many of the topics we have discussed, one thing I still struggle with are the different types of tissues. I have recently made flashcards regarding the different types of epithelial tissues. I hope to keep referring back to them in order to achieve a better understanding of them. Tissues compose much of the human body, and I can only imagine how many more times they will show up again throughout the year. So all I can really do is keep studying and working hard to memorize the majority of these tissues, and I plan to have a great understanding of just about everything I possible can, in order to earn that A that I have been striving for!

WISH MY LUCK!!! =)
 

"The Body Shop" A Review By Kandace!!!

Link
The article "The Body Shop," discusses the processes that scientists are now going through to grow or make replacement body parts for the human body. About 15 years ago Joseph Vacanti and Bob Langer created a new process of growing human tissues in a lab. With the contributions of Vacanti's brother and other researchers, throughout the country, they all hope to be able to make replacement organs for the many people in this world that need them.
     Skin is the largest organ in the human body, and it is no surprise that skin is the first "neo-organ" to be approved by the United States Food and Drug Administration. Many burn victims and patients with skin sores or ulcers have skin that it nearly dead and is unable to function properly to protect their body. That is where this new skin plays a major roll. This skin is able to aid both, burn victims and skin sores or ulcers. It is a hope among many that within the next couple of years, scientists will be able to produce, lab-grown cartilage and bone. Although we have the technology to do these experiments "neo-organs," are not the simplest things to grow or create.
     In order to grow tissues properly in a lab, scientist have had to literally mimic the physical environment in which cells grow naturally. Vacanti and Langer together created a scaffold on which cells can be planted or seeded. The scaffold they produced consists of biodegradable materials that are long stringy strands that attach together. The purpose of this scaffolding is to properly provide cells with a better access to waste removal and nutrients. Also these scaffoldings can be molded into many different shapes and sizes which can produce a custom grown tissue.
     Overall this was actually a very interesting subject to learn about, and I would have never thought that we would have the ability to grow human tissues in a lab. Let alone be engineering tissue that will ultimately help thousands of people throughout our world, whether it be a small or large impact this is truly an advancement in human technology!!!
    
     This picture took me by surprise because it just happens to be a real human ear growing on the back of a lab mouse. After reading this entry I was shocked on how the mouses body was able to handle the human tissue without its immune system failing to support it. However after reading further I found that this particular mouse was bred to lack an immune system so that throughout this process it would not reject the human tissue.
