Pharmacology of the internal anal sphincter and abnormalities in faecal incontinence

Abstract

Studies of anorectal physiology and in-vivo experiments on the innervation of the anorectum have provided considerable information about anorectal function. Additional information regarding the receptors and nerves involved in the control of the internal anal sphincter function has been obtained from in-vitro studies of isolated muscle strips of the internal anal sphincter.
