GREY’S ANATOMY star Chyler Leigh checks into Hollywood 411 to give Chris Harrison the low down on a painful storyline. Chyler also shed’s some light on the GREY’S/PRIVATE PRACTICE crossover, and her own hospital adventure!

Check out these skeletal models you build on with clay. Hear from students and teachers who use them to study and learn anatomy.

If you are amongst the many people who have taken a challenging class like anatomy or chemistry, you know how hard it is to study correctly. I took these classes as a sophomore in college. Back then it was hard to balance friends, school, and sports all together. It was easy for me to study for every other class except for anatomy. Luckily for me, my other roommates were in the class as well, and all studied a lot. One day we all thought it would be best to put all of your studying habits together to make this class way easier, and here is what we did.

First:

Find a group to study with. It worked out perfectly for my roommates and I because we studied together. We used the study guide to make a foundation of what we needed to learn for each test, this was great because we could then assign each person a part of the study guide to fill out. This made it so we could start learning the information faster, because we all didn’t have to spend hours filling out the study guide on our own.

Two:

Organization is key. This is very important when studying for classes such as chemistry, biology, or anatomy. Now that you have finished your study guide, you know what is on the test, and now can organize it into chapters. Take away the most important notes and try re-writing them. Writing down the notes over and over again will help you remember what you need to know much more accurately then just looking at your notes.

Third:

Understand the pictures. If you are learning about the human body it is almost pointless if you don’t know where the certain functions are taking place. My advice is to understand all the diagrams and pictures before you start to learn about what is going on. Therefore you will visualize what is going on in the actual spot that it is happening in.

Homo sapiens are always evolving even as we speak. You don’t feel it happening but rest assured it is an ongoing process. We all still have an appendix even though we don’t need it to survive. There was a time, however, when it served a purpose to our bodies.

Many thousands of years ago when we were hunters-gatherers we were constantly on the go and eating anything that we could find at the time. This meant that we ate a wide variety of vegetation that we don’t eat today.

Back then the appendix was most likely an organ the size of the stomach and was need for the diets of our ancestors. Over the period of many thousand years, due to lack of use it has decreased in size is of no use at all to us.

We are the only ones that have an appendix and do not have a use for it. On the other side of the coin there are animals like the koala bear that don’t eat meat but still use their appendix.

Koala Bears eat only vegetation and use their appendix to break down the specific chemical makeup of the plants and leaves that they consume. Maybe if humans ate more of a vegetarian diet they might develop a need for an appendix. If this were to be the case it would take our bodies thousands of years to evolve back to being able to use our appendix.

The mere fact that we no longer have a need for our appendix doesn’t mean that it’s just going to vanish from our bodies completely. It is something that we needed in the past and is still with us. It is only one of the things that we still carry around with us and don’t use.

The appendix serves absolutely no purpose for us at all anymore. This is proven by the fact that there are many people leading healthy happy lives that have had their appendix removed.

It is quite possible that one day none of humanity will have an appendix and it will just be something remembered in the history of the evolution of human anatomy.
