Figure 3.

Basal tone resulted in a significant increase in the unloaded thickness at the proximal (black) and distal (grey) regions with the distal region being thicker than the proximal (a). The volume of the vagina was larger for the distal region than for the proximal, with (open) and without (filled) basal tone (b). Basal tone induced a significant decrease in outer diameter in the proximal region (c). The proximal region presented a larger outer diameter than the distal, with and without basal tone. There was a decrease in physiological length with basal tone for the proximal and distal regions (d). Data are reported as mean ± s.e.m. Statistical significance is denoted by state *p < 0.05 and **p < 0.01, as well as location ^†p < 0.05 and ^††p < 0.01.
