The Nervous System
041 - Animal Nervous System
Paul Andersen begins this podcast with a discussion of brain lateralization and gives a brief demonstration of tests that were performed on split-brain individuals. He then discusses the major parts of a neuron and explains how action potentials are generated using voltage-gated ion channels. He explains how neurotransmitters transmit messages across a synapse and how these messages can be either inhibitory or excitatory.

Mr. Anderson you are literally the lifeline of my whole bio class. You can explain more in 5 minutes than my teacher can in 5 weeks
Keep in mind: In the PNS, myelin sheaths are made out of Schwann cells. In the CNS, myelin sheaths are made out of oligodendrocytes.
If all teachers and professors taught like you, our world would be completely different. Thank you
You have such a knack for making a complex subject understandable. Salty banana is exactly the type of easy to remember memory prompt which is so useful in an exam. Thank you
I definatly didn't say it was a flower I thought it was the color weel

Me too bro!
you are an excellent teacher, so clear, you make it simple and I can't thank you enough for all your videos, they are helping me gain the understanding I do not get in class. you are a true gift from spirit. rainbow
Salty banana. Great analogy, really helped me understand where the concentration gradients began and changed. Thanks!

Took A&P and gained a rough understanding of the Na+/K pump, action potential, and nerve synapses, but now everything is suddenly clear after watching this video. Thank you so much for this.
That moment when you finally realize what the lines on a heart monitor are

You mean the action potential? It's actually a bit different. The heart trace is a composite from the electrical activities from the various ventricles and valves of the heart. The heart trace looks quite different, but is similar in that it has an excitatory and refactory stage. The different peaks can tell you a lot about the different fuctions of the heart, like long QT. The peaks are named QRST in respective order and a heart with the long QT will take longer to go through the 4 peaks making it less efficient at distributing oxgyen to the body. Someone more qualified may explain this better, but I don't think the action potential is the same as the heart trace.
I am so glad that I found your videos. They have made a huge difference in my gpa for Human Biology! Thank you so much for taking all this time....
You are better than what my science teacher has ever explained in his class. Very specific and useful for science dummies like me! Love you and thank you sooo much!!
My AP Bio teacher assigns these to us for HW and it's honestly so helpful!! You explain everything so simply so I can understand but it gets the lesson through really well!
So informative and simplified! I've been watching your videos since Grade 12 and they've continued to help me through first year university science courses. Thank you so much for your help!
Just wanted to say that i've watched this video probably four times and each time I've been confused about action potentials and the potassium pump - but finally I got it! I feel so proud of myself but also so thankful to you for explaining this process so well. Thank you so much for all the hard work you do!!
I've watched a lot of your videos now and this is the the best one so far IMO. Very well presented.

You are a GENIUS, Mr. Anderson! Thank You!
you just taught me what my teacher couldn't for 2 classes, I swear I almost gave up studying for this test. god bless you!
I'm 68 years old and just discovered this series. What a great way to finally learn some biology--I could listen to you all day! Thanks, you gifted teacher. "Every day's a school day."
I took anatomy and physiology over 5 years ago, and I kinda forgot a little and your videos are serving as a refresher to my dimmed memory. I'm going to pass the Teas Test with ease.
The salty banana is the first time I was able to get the ions correct. Each other explanation is confusing about what flows where-when. Brilliant, as simple as anything but explains it perfectly.
Oh my God I am so grateful for this man. he is the best explaining this subject. I can say i have learnt more with him than with my teacher. She only read ppt at class. Thanks Mr. Anderson, you are the best.
Haha 'salty banana', that's the best analogy ever, cheers!
your voice is so relaxing but not the bad relaxing so i don't fall asleep like i usually do in class

Amazing.. I defiently just told my Physiology professor about your videos and how great & helpful they are. I appreciate all you have taught me this semester. Keep up the GREAT work
My favourite video - it helped me in school, in a biology olympiad and is still helping me in college. Thank you very much!
This guy should be my biology professor!! short lessons that summarize a whole chapter.
You dont know how much your videos help me
I hate this topic but you make it seem so easy. But we have a lot more information regarding this like different types of channels, etc. I wish we just had this much :(
My teacher showed us this video in class a while ago... I live in germany but our school lets us choose between biology class in german or in english, so this is extremely helpful for me, so THANK YOU!
You are awesome. I would never be able to pass A&P without your videos. I got over 100 on my last exam, when the class average was only 80, because of these videos. Thank you so much!!
Good sir, you make biology interesting. Got an A on my test thanks to you :3
Thanks so much for all the videos!!!!!! I couldn't have passed my anatomy and physiology class without them!!!
Dr. Bozeman, you are the GOAT! they way you are able to break down a video in more in depth detail as well as present it so we can understand it is amazing!! Please continue to do what you do because you help me understand Bio!

Based on what I read on pewdiepie (I honestly have no idea why KZread users behave the way they do), I guess sharing his links counts a lot for the algorithm. Try doing that, it will help the GOAT.
The explanation of the split brain thing reminds me of that episode of House with the guy whose left hand hated everyone.

Bailey Edwards The human brain is a interesting machine . Who know to what extend a person can manipulate the human body with the right conditioning and training or access the subconscious mind. I know some people who been training for years in such disciplines and technique's. They can control their heart beat and body temperatures and reset their sense of smell. When people get used to a smell they stop noticing it , They can also boost up the sense of smell and even able to push aside external distraction to more easily focus on sound and this makes them better at detecting lies. When people lie theirs a small shift in sound or variation for some people it is very slight almost unnoticeable for others it more bold and easier to detect. They keep trying to develop new disciplines and techniques to manipulate their own body and minds. I understand they are currently trying to mimic the effect of channeling electrical power through them without killing them. They heard about a man who is able to do it and are trying to mimic the effect. People sense accurate things about people all the time on a instinctual level. I wonder if its genetic or trainable. They do look very much alike.

+Bailey Edwards yeah, I did a research project on alien hand syndrome (inspired by that episode of house), the corpus callosum surgery is actually one of its main causes too.
Wow, thank you so much for this video. I could not, for the life of me, understand what an action potential was and you completely cleared that up for me.
bozemans science and craig savage videos are enuff for me to score top marks thanks alot to both of u..you guys are just amazing..
You've outdone yourself again Mr. Bozeman!!!!
I am loving the way you explain things, Thank you !!!!!!
Thanks for all your work
Bozeman Science, my favorite KZreadr!!!
You are THE BEST professor ever!!
This is so great! Thank you so much for making it
Your voice is so soothing!
Glad I'm not the only bio student coming here with a jumble of confusing notes about action potentials and Na/K pumps, looking for a better explanation. 🥴 You actually make sense. But I'll still need to watch this one a few more times haha
these videos are literally the reason i'm doing well in bio. Thank you so much! So reliable as well !!

Super cool then and now 2021...thanks
TYSM! I'm understanding this for the first time!
Thank you so much. I've been trying to understand neeons and how action potentials work for my bio class. This really helped.
You're awesome! You explain everything better than my professor in half the time!
Thank you so much mr Anderson. I wouldn't be surviving ap bio without these videos
Many thanks for these informative, easy to understand videos, am studying neuroscience at the moment and these straightforward explanations are exquisite. I have I hope (thanks to my neurons) kept most of the info imparted.
your videos are great! seriously helping me get through college right now.
you've been a blessing to us... thank you... thank you...
