Puborectalis Muscle, Superior View

Description

Centered within the pelvic outlet, the puborectalis forms a paired, U shaped sling that curves posteriorly around the anorectal junction, with its right and left limbs arising from the posterior aspect of the pubic body near the pubic symphysis. From this superior perspective, the muscle sits as the most medial component of the levator ani, closely related laterally to pubococcygeus and iliococcygeus, and positioned anterior to the coccygeus muscle and ischial spines. The bony ring of the male pelvis frames the field, including the iliac bones laterally and the pubic arch anteriorly. Orientation is clear. Puborectalis matters because it is the dynamic component of the anorectal angle. By drawing the anorectal junction anteriorly, it supports continence; with relaxation during defecation, the sling lengthens and the angle straightens, a mechanism evaluated on defecography and dynamic pelvic MRI. Injury or denervation of the levator ani, including puborectalis, is discussed in male pelvic floor dysfunction and fecal incontinence, and it becomes a landmark in operations that work in the intersphincteric plane or low anterior resection where preservation of pelvic floor integrity affects postoperative function. Use this illustration in pelvic anatomy teaching for medical and PA curricula, in colorectal surgery or gastroenterology texts explaining the anorectal angle, and in continence clinic patient education materials that need a clean superior map of the levator ani sling. It also fits urology and pelvic floor physiotherapy references when describing male pelvic floor muscle training targets beyond the external anal sphincter.
