Oh I'm partial to the odd Beta-agonist; gotta keep the body ready and willing!
Alcohol is indeed a delightful past-time.
beta-agonist, is that the same as a beat blocker?

No, a beta blocker is a beta-antagonist. It slows the heart down. Beta agonist mimics noradrenaline with increased effect and increases the heart rate.

I don't think they do, I was referring to Beta-agonists which have the opposite pharmacology to the blockers. Although you can become dependent on beta-blockers such as Propanolol.

Move away from the alcohol! At least til after the exams! If you're anything like me you've left it all til the last minute and are now frantically trying to catch up via the "Crash Course" books. However, my exams were last week and went horribly so all I can say is REVISE! You'll feel so much better after the week-from-hell is over.

THE 2 WEEKS FROM HELL YOU MEAN! and your exams are over, how annoying! Are you done for this year then? Yesterday I was in the library using crash course cardiology from 10am till 10pm.

Oh, I thought you said a beta blocker WAS a beta antagonist. Perhaps you missed out the crucial "not" there! I knew you could become dependent on them, but there seems to be no other solution <sigh>

a beta blocker is a beta antagonist. Maybe we should draw the line with that one.

Yes, correct, basically anything with -olol at the end.

I have a 'catchy' way to remember my adrenoceptors.

Alpha 1 contracts vascular smooth muscle

Alpha 2 does something with contraction as well

Beta 1 increases heart rate and contractability

Beta 2 relaxes blood vessels in skeletal muscle and relaxes bronchiole smooth muscle.

God, it's so catchy it's almost a song.

Not started systems yet (we do way too much cellular and biochemical science here :mad: ).

I only know how to interpret a 12-lead ECG and that's about it.
