: Obstetrical international anal sphincter (EAS) personnel casualty and resulting dysfunction are leading risk of exposure factors for brute fecal excretion (FI). Limited cognition of the EAS structure-function relationship hinders treatment optimization. We directly plumbed functionally pertinent integral parameters of human EAS and tested whether vaginal delivery alters the EAS structure-function relationship.: Major predictors of in vivo EAS office were compared between specimens procured from vaginally nulliparous (VN, n = 5) and vaginally parous (VP, n = 7) dead body donors: operational segment length (L), which dictates force-length relationship; biological science cross-sectional area (PCSA), which determines isometrical force-generating capacity; fiber temporal property (L), obligated for hooligan digression and contracted velocity; and roughneck stiffness.
