Current Events > I have to internalize the answers to 8 neurophysiology q's by monday night

(+) Yeah! (+)

Can't be assed to do it though

They're fairly lengthy answers >_<

Really? Do you know neurophysiology?

1. How is the resting potential of a neuron maintained? Include the mechanism of action of the sodium potassium ATPase and other channels.
2. What is the function of microtubules in a neuron?
3. Describe and explain the experiments of Hodgkin, Huxley and Katz to elucidate the mechanisms and molecular basis of the action potential.
4. Explain why neurons with axons of a larger diameter conduct a nervous impulse faster than neurons with a smaller diameter axon. Include the time and length constraints and explain and describe each.
5. What influences the passive properties of a neuron and how will they affect the transmission of a nervous impulse?
7. How is a cation channel selective for a particular ion (e.g. potassium or sodium)?
8. What is the effect of the equilibrium potential of an ion on its conductance through a channel in the neuronal membrane?

Resting potential is maintained via a series of potassium/sodium/chloride channels. Just watch a youtube video, its very easy. I would suggest drawing a giant neuron and drawing out where the channels are and what triggers them and there the electrolytes are.

Microtubules transport shit along the axon. Again, draw a neuron and draw these.

No idea what those experiments are.

I would have to brush up on my physiology to tell you why larger diameter = faster.

I dont feel like answer the rest of em.

Just basically draw it all out and itll make sense.

Thanks for the help. But I have all the answers already I just have to find a way to cram them in my head so I can write down a sufficiently detailed answer in the blue book in class by monday night =/

Translation: Wikipedia didn't go into enough detail.

Anything neuro and anything physiology can be easily retained if it makes logical sense to you. Personally I had to draw everything out in physio and in neuro, and go over it slowly to figure out logically how everything works. After that, it sticks with you for years and makes sense so you can answer complicated questions and retain large amounts of information. If ur straight memorizing it, you wont retain as much.

gl im out.

Thanks bud

Perhaps it would have helped if you attended the class ;P

Lmao how'd you know I didn't?

Honestly it wouldn't have helped. My professor is all over the place and can't sustain a thought. I had her another semester and attended all her classes that time and it didn't help one bit, had to use extra sources.

If ur serious about doing well in ur class, I can recommend you a killer book. Get "Physiology" by Costanzo. Its a great textbook, its not too wordy, not too long, you can read chapters relatively quickly, it explains everything clearly, detail, and in simple words so its easily understandable. She breaks down tough concepts and makes them very easy to understand.

With that book, I aced physiology and physio lab in undergrad, and I actually used that book for medical physiology in medical school and I again aced it.

I'll see if I can get a hold of it

You posted about it at some point.

Sucks that you have a shitty professor, neurophysiology can be really interesting. Though, with a grad level course, it's to be expected that a lot of the learning is done independently.
