Effects of drugs on contractions elicited by transmural stimulation of guinea pig ileum


This experiment has three parts. Part 1 requires the user to determine a stimulus voltage which elicits a response which is just sub-maximal. Part 2 uses that stimulus voltage to investigate the effects of various drugs (atropine, clonidine, morphine, naloxone, phentolamine). The user then answers questions on the actions of the drugs. Part 3 requires the user to investigate the effects of naloxone on the action of morphine, and phentolamine on the action of clonidine. Again there are questions testing understanding of  the data.
