damn, did I get it wrong somewhere?

(I should have mentioned i'm an idiot before posting)
Well actually I was only doing that because you wrote stuff I already had. But now I realise you were talking out of context too haha. The reason calcium slows the action potential won't be that.

:p:

How's second year? The really tough pre-clinical year aye.

Ditto. I'm ashamed that I supposedly have two years more medical knowledge than him and yet understood about three words of that entire conversation :getmecoat:
You want to be an orthopod, no? Like it matters how much you know about ACh/muscarinic receptors/etc... :p:

Saturday night in to conserve cash so I can afford to go home at some point.


I didn't even drink or smoke after our hall formal last week. Took some doing, but I feel really proud of myself.

I'm glad someone appreciates the sig! It's mostly going well, our formatives are on monday and to prevent another epic fail I'm trying to revise. It's going really slowly and I have two modules to complete tomorrow along with sociology and the rest of PDS. Bad times. Looking forward to intermodular week though, in a way I get double the fun as I get one next week and my second year buddies will be celebrating theirs the week after so I'm going to join the festivities on both weeks. Not particularly pertaining to a healthy liver/bank balance/academic workload but gaaah, when did I ever have a healthy any of those things?


How's it going for you? How's second year shizz?
Ah best of luck with that It'll be great after they're over! have you got a spotter? I'm not sure if they've just taken them out of mocks completely or if they just don't have any in second year =\

ah sociology.. that old beast :P I saw scambler on tcr the other day, haven't seen him at all this year I don't think! but double celebrations sounds like a good deal and hey, why do you think the liver regenerates? :P

ah right :P - I was just writing in reponse to Woody's response to your awesome explanation.. I thought he was asking how ACh can both trigger action potentials and exert negative inotropy (ie serve two different functions) and I just thought I'd emphasise the whole receptor theory thing... but reading back I don't think that was the right interpretation of his comment anyway, and I was talking about something completely different

Second year is a mixed bag - Neuro is really interesting and Endo is pretty easy, but there's just so many lectures! Have been working through the MEQ past papers preparing for the mocks, seems the best bet atm! How's fourth year? Do you spend much time at UCH?

Dunno how much it's changed but past papers = godsend.
Endo is amazing - so well taught. And CALs to cover everything.

Haven't spent any time at UCH at all. My clinics placements in 3rd year were the Whit and the Free.

Do you have all the past papers?

Its talking about skeletal muscle mate. If you think very carefully - cardiac muscle is self stimulating :p: Autogenicity and all that.

The second bit I'd have to quickly look up as I don't remember of the top of my head.

(Original post by Tech)
Neurotransmitters functions are largely dictated by the receptor - It all depends on the exact cell, system or whatever you're talking about. It (ACh) triggers action potentials in the NMJ because the receptors are nicotinic. It hyperpolarizes the cardiac (nodal) cells because the receptors are muscarinic (M2).

hope that clears it up a bit! and off the top of my head, I think it's calcium that binds to troponin, which pulls tropomyosin off actin (allowing the myosin to work its magic)

but you'd want to check that before writing it in an exam
Thank you both kindly, I was actually going to ask why ACh stimulated APs in skeletal muscle but not cardiac muscle (though the answer seems painfully obvious now) so both your posts complemented very nicely! Thanks very much for helping.

I'm revising Psych and actually finding it really interesting. I've read more of my psych textbook in 2 days than I have of any other textbook in the last three years. I blame my psych tutor who told me to consider it as a career :hmmm:
that's impressive! i find psych interesting too but i cant see myslef as a psychiatrist. i will go nuts too. im already getting paranoid about being paranoid, having an eating disroder or a borderline personality disorder just after 3 weeks of psych PBL cases!!!

The CALs make a really nice change! shame you haven't spent any time at UCH, I've been at the whit and free for preclinics, was hoping in a couple of years I'd get to be at UCH although, if I get the BSc I want I think I might be spending some time there :cool:

I've got all the pps thanks (at least I think!), and some nice psychology summary files to boot.. just need to actually do some work now :P I think the main change for our year is they're taking anatomy out of the MEQs.. everything else seems similar though.

You might do! It's completely random which two sites you get... unless you put in some exceptional circumstances or something.
What BSc you going for?
