Neurophysiology Lab

Today during anatomy we did a virtual lab where we dissected a leech! We got a leech and soaked it in a salt solution to take care of the exracellular space, then we began to dissect it. We cut it down the midline, and then removed its guts and connective tissue; leaving th nerve cells visible. With the nerve cells visible we were able to find a ganglion cell. We then used a micromanioulator and three different stimuli (feather, probe, and forceps) to stimulate the ganglion cell and record its responses to stimuli. After testing the cell we injected it in different areas with dye and put it under a UV light to see the cell body and other cell parts after stimulated. With this we were able o see that different types of  cells react differently to different types of stimuli. The feather, probe and forceps created different levels of stimulation within the different cell and since each celll had different functions, all the cells produced different responses to the stimuli.

Friday questions

This week I learned most of the origin and insertion of muscles as well as the function of lots of muscles
I completed the "book" and finished my anatomy test! What a relief.
This week my goals are to completely catch up on everything in anatomy and start on our new unit!

Fridays!

This week I've learned several things, the most pertinent being how muscles function with energy use.
This week I completed more packets in the "book" and also completed 2 quizzes on the muscles!
My goals for next week are to complete all packets and homework around Wednesday; giving me plenty of time to study!

Friday questions!

This week I have completed some packets, hopefully starting to make a debt in the "book".
I have learned several things this week, many for the video watched in class. I learned that the body can withstand a ton a pressure without breaking the bone!
My goals throughout this week are to continue working on the packets and study for our upcoming quizzes!

Weekly 3 questions

1. This week I completed the anatomy and physiology of the skeletal system, which will be a major help to our next section.

2.Throughout this week I have learned many interesting fun facts! Two happen to stick out the most; Did you know that during surgery you can get unplugged from the oxygen machine and you can live up to 5 MINUTES! I know it was a shocker to me too. On a more serious note I also learned that muscles are made up of one long cell with many nucleus's, and you are born with the amount of muscles cells you will have throughout your entire life.

3. My goals for this upcoming week are to start the anatomy packets and take all of the flipped notes. 

Human Consciousness

Finding a book to read and like may be simple for many, but happens to be a great challenge for others. Unfortunately fitting into the "challenges" category, finding a book seemed like it was going to be a struggle. However, it was not we got a list of books and a brief description of each book. One book really seemed to pop out. The book being A Brief Tour of Human Consciousness. Knowing my fascination with brains and how and why we do certain things, this book was a perfect match. Everything read so far in this book has been interesting, possible disturbing, but the most intriguing thing is, how the brain can generate illusions as well as delusions. Essentially we can trick ourselves it to thinking or believing practically anything. Disturbing or fascinating as that maybe, it is the truth on how our brain works, and that is why this book is the perfect choice.

TED talk: Cell v.s. Silk

Silk and cells can both be categorized as versatile objects. With each, there are many different jobs they can do. Cells make up everything in your body, while silk is used for clothing, films, dvr, or even to make things have a 3-D appearance. However, like cells there are are many diffrent types of silk, but all silk is simply made up of water and protein. Silks can literally be used for almost anything given there ability to adapt and change.Silk is biodegradable and biocompatable meaning it either regenerates itself or adapts or breaks down. Cells however are categorized by size, shape, and function. Each cell has their own function that they do, they also each have a specific form. With that the body is able to function and maintain its equillibrium. This video ties in with our cell differentiation and themes of anatomy and physiology because it shows how a simple silk thread can become much more by simply changing its complextion. By changing the complextion we change the form and function of the silk thread. Form, function and change are the definitions of anantomy and physiology. This ties into cell differentiation because the silk a once less specialized cell develops into a distinct form and function.
