Lab Poster

This is a picture of the poster that we made from our own lab that we made up. Our lab was to see how your heart rate changed playing wii tennis, and playing regular tennis.

Sheep Brain Dissection

This is a picture of the brain that our group dissected. We cut it down the mid-section of the brain like a bread loaf. 

We have been talking about the brain in our class and actually dissecting the brain let us see the parts of the brain that we were talking about such as the white matter and gray matter that you can see in the picture above. When dissecting the brain, we had to first remove the cover off of the brain, and that is the shell like coating that you see on the top of the picture. It was weird at first to see a real brain, and that all the pictures and things that you see of brains, it actually really looks like that. With all the the learning of brains in class it's really nice to get the opportunity to see the real thing, and it helps you to see the anatomy of an actual brain.
When dissecting the brain, we first got all the tools that we needed. We got a tray, rubber mat, scissors, scalpel, and probe. we then figured out in our group which way we were going to cut our brain, and we decided to cut it down the mid section. It came out pretty good and we saw everything really clear! We went around after we were done and looked at everyone else's brains and saw the different cuts that different groups did. It was a fun dissection and I would definitely do something like that again.

Here are a couple pictures of the other brains that the other groups dissected.

Parkinson's Disease

Here is a link to my Parkinson's Disease Presentation.  Parkinson's Disease is a very interesting thing to learn about! I hope you Enjoy it!! :) :)

Leech Neurophysiology Lab

We have been working on a Leech Neurophysiology Lab in class on our computers. Like Our teacher said, it would be nice to actually do this in class, but all the equipment and the things we need would be way too expensive. It was pretty cool to do it on the computer, because even with the virtual one it seemed real. The things we did with all the equipment was what we would have done hands on if we would have had everything that we needed.
Equipment:

• Leech Tank
• Dissection tank
• Scalpel
• pins
• scissors
• forceps
• probe
• 20% ethanol
• Leech tongs
• Dissection Microscope
• Micromanipulator
• Oscilloscope
• A leech
• feather

What we pretty much did in this lab was dissect a leech all the way down to look at it's nervous cells that are responsible for collecting touch information from it's skin to it's brain.
When we first started the lab, it introduced all the supplies that we would be using at first. I then inserted the leech tongs into the beaker, and anesthetize the leech. I then stretched the leech out and pinned both the anterior and posterior sides down. Then i got the scalpel and cut the leech open, got the forceps, and opened the incision. Next step was to grab the probe and remove the guts and connective tissues. I then put it under the microscope, made an incision with the scalpel and removed it with the forceps. I then got the scalpel again and cut a section, and pinned it down to the mat. We then looked at it under the microscope and made another incision in the sinus, then another. ( It looked ind of like an X after we were done making incisions). I then clicked on the micro manipulator, probed a cell, then i injected the cell with dye and looked at it underneath the UV switch.

This is the graph that tells you what your cell is at the end of the lab:
