Mechanism for CPP by stimulation of the VP. Left figure 3D view of organs and VP which serves as a type of “relay” for end organ afferents from bladder “B,” lower abdominal and pelvic muscles “M,” vagina/vulva “V,” rectum “R.” G = force of gravity which stimulates VP if they are not sufficiently supported by USLs. By permission S Muctar. Right figure 3D view showing pathways of impulses to and from the cortex (small arrows) via the hypogastric (Frankenhauser) plexus (T11-L2). And the effect of USL laxity “L.”
