Neuronal Control of Gastrointestinal Smooth Muscle: Worksheet

...

TO THE RELEVANT TABLES AND FIGURES (i.e. your experimental results), explain how you have determined if Drug A or Drug B are noradrenaline or acetylcholine. In your response you must refer to the normal actions of these drugs on smooth muscle function in the gut.

4) Discuss how your experimental protocols have enabled you to determine if you are stimulating sympathetic or parasympathetic nerves. YOU MUST REFER TO THE RELEVANT FIGURES AND TABLES (i.e. your experimental results) in order to support your conclusions. . In your response you must refer to the normal actions of these drugs on smooth muscle function in the gut (including their effects on smooth muscle receptors). If your data analysis does not show any clear results - explain how you might alter your experimental protocols for future experiments.

5) Why do you think that nearly all of the preparations in the practical class show a predominantly sympathetically-mediated motility response? (please note, there are a wide range of responses to this question).

CONCLUSION (NO MORE THAN 100 WORDS)

Provide a brief conclusion of what you consider this practical demonstrated about the control of intestinal contractions by the autonomic nervous system.
