puborectalis muscle

pu·bo·rec·ta·lis mus·cle

(pyū'bō-rek-tā'lis mŭs'ĕl)
The medial part of the musculus levator ani (pubococcygeus muscle) that passes from the body of the pubis around the anus to form a muscular sling at the level of the anorectal junction; it contracts to increase the perineal flexure during a peristalsis to maintain fecal continence and relaxes to allow defecation.
Synonym(s): musculus puborectalis [TA] , puborectal muscle.

puborectalis muscle

Pelvic muscle, part of levator ani. Origin: back surface of pubis. Insertion: joins other levator ani muscles forming a bowl shaped diaphragm, encircles anal canal, and attaches to sacrum and coccyx. Nerve: inferior rectal and sacral (S4). Action: supports pelvis, holds anal canal at right angle to rectum.

This examination assessed for anterior movement of the puborectalis, lift of the PFM, complete relaxation of the PFM, and length of hold.
In an effort to develop safer and less invasive passage of the trocar, or needle, through the retropubic region a transobturator tape was introduced24 which passes through the obturator and puborectalis muscles, reproducing the natural suspension fascia of the urethra while preserving the retropubic space.
17) Chronic proctalgia is further characterized into two subtypes, levator ani syndrome and unspecified functional anorectal pain, based on the presence or absence of reported tenderness during posterior traction on the puborectalis musculature.
The MRI findings noted in this study include location and morphology of neorectum, presence of scarring, presence of peritoneal fat herniation, development of puborectalis and external sphincter muscles, associated vertebral and spinal cord anomalies and any other abnormalities.
Anismus, the abnormal contraction of the external anal sphincter and puborectalis muscle during attempted defecation, is another problem that can occur in synergy with constipation in approximately 65% of PD patients, which is more frequently observed during "off" periods [16, 28, 47].
This collection of cysts paralleled and was adjacent to the left puborectalis muscle and breached the left levator ani.
The levator ani is further made up of the pubococcygeus, puborectalis, and iliococcygeus muscles.
This S-shaped acrylic wand is inserted into the vagina and provides direct internal pressure on the pubococcygeus and puborectalis muscles, facilitating trigger point release.
Pain inside the pelvis, especially on the pelvic sidewall (obturator or puborectalis complex) usually is related to mechanical tension.
