Figure 6. Effects of lesioning the submucosal plexus or myenteric plexus on vasodilatation.
Summary of the percentage of mean peak dilatations evoked by balloon distension (3 distensions, ≈1 Hz) or mucosal stroking (4 strokes, ≈1 Hz) after the myenteric plexus or submucosal plexus was severed using surgical lesioning techniques. Lesions were made approximately equidistant from the stimulating and recording sites (n = 3–7 arterioles for each group).
