puborectalis (muscle)

(redirected from Braune muscle)

pu·bo·rec·ta·lis (mus·cle)

the medial part of the pubococcygeus muscle (levator ani) that passes from the body of the pubis around the posterior aspect of the anus to form a muscular sling at the level of the anorectal junction; it contracts to increase the anorectal (perineal) flexure during a peristalsis to maintain fecal continence and relaxes to allow defecation.
