    For why we shiver I put, increased temperature reduces activity of acetylcholinesterase, so ACh is not hydrolysed and remains in receptor, so sodium channels remain open causing the continued stimulation of action potentials in post-synaptic membrane leading to muscles. Could be wrong, anyone else put something like that?
    I don't think all the stuff about acetylcholine is relevant. However, you put increased temperature which might be enough to get you a mark. I think the answer is that you shiver to increase body temperature to make your body less hospitable to pathogens.

    This isn't a condition, which is why this wasn't an answer

    It specifically asked for a condition, this is an unknown diagnosis

    I may not be much help here since I fail to remember the order. But I think they were

    a) Which go from the CNS - M

    b) which go connect with others through synapses - B

    c) which go to an effector - M

    If all of that is true about pathogens, then why would the body simultaneously sweat?

    Yes i wrote a note saying that went up the most however it asked for a cause and I can only assume they wanted one that was a clear cause not the undiagnosed! Could be wrong though

    Sounds like a mean paper. TBH this has been a common occurrence for OCR over the last few years. They make unit 4 the hardest in terms of content with all the different processes to remember and then they just question you on crap which people who haven't learnt A level biology could do. I'm hoping with the new syllabus they stop wasting paper space by adding **** questions and actually test you on what you have learnt. Applied questions are fine, they are useful in fact but at least make it relevant to the material learnt.
