Qs regarding the urrent study design: Immune response & the nervous system

[Merlyn]

Hello! My teacher flew passed this topic and she skipped a lot of information that I thought was quite... important.
So some questions to confirm what I need to know:

- How detailed do we need to know about the action potential?
- Do we need to know about Class 1 and Class 2 MHC markers?
- Do we need to know about the Complement system?
- Do we need to know about any other T lymphocite cell other than Tc and Th cells?
- Do we need to know about the different types of antibodies?

Thank you! ^^

1. Yes.
2. Yes - but knowing which cells have which MHC markers and their main function is more than enough
3. I don't remember talking about the Complement system much last year, but I guess just knowing what Complement Proteins do would be sufficient
4. There are T-regulatory cells but you don't really need to know about it
5. You don't really need to know about the different classes of antibodies, but you should know about the role of IgE antibodies in an allergic response

ahhhh. Okay. I guess I'll just do some self research then.
So how detailed do I need to know about the action potential?
Resting potential, depolarisation, threshold potential, repolarisation, refractory period detail? Haha

[Shenz0r]

Not too much detail - if you learnt the resting potential -> depolarisation -> hyperpolarisation -> back to resting potential, that would be actually more than enough. It is unlikely that they'll ask you to describe the whole process.

I'm thinking more like this, for VCE Bio:

Need to know that action potentials travel down the length of the axon
Action potentials are regenerative (so they cause other areas to become depolarised - kinda like a Mexican wave)
Action potentials are all-or-nothing events
Action potentials can only be triggered above a certain threshold
Action potentials are a very fast and direct way of transmitting nervous impulses
The speed of an action potential can be increased by myelination of the axon

You need to be aware of the resting potential, how stimulations of a stimulus will raise the potential to the threshold. Once that is reached, an action potential is generated (an all-or-nothing process), you then have to return to the resting potential (refractory period) before another action potential can be generated. You need to know about how the neuron at rest is polarised, it is depolarised during the generation of an action potential, and how it is repolarised during the refractory period.

Sorry I can't help with the rest because I haven't yet started Immunity: Defence against disease!
