In the following experiments, you will study some of the physiological and pharmacological properties of visceral smooth muscle taken from the rabbit ileum. (The ileum is the last part of the small intestine). You will vary the Ca 2+ concentration, and the temperature and oxygen content of the medium surrounding the muscle. In addition, you will investigate the effects of acetylcholine, atropine, and norepinephrine on the muscle tissue.
You will observe the recordings before and after the various treatments and look for and measure changes in the rhythmicity and in the tonus of the smooth muscle contractions. The Biopac Student Lab PRO will be used to record the contractions.
After preparing the smooth muscle for testing, the student will record (and compare to baseline) the effects of the following conditions:
