The region of the perineum can be considered a distinct area from pelvic cavity, with the two regions separated by the pelvic diaphragm. The perianal area (peri-and anal) is a subset of the perineum. The following areas are thus classified as parts of the perineal region: perineal pouches: superficial and deep (see above for details)
The urogenital triangle is the area bound by a triangle with one ... Muscles Superficial transverse perineal muscle ... The posterior aspect of the rectum exposed by ...
The function of the muscle is fixation of the perineal body (central tendon of perineum), support of the pelvic floor, expulsion of semen in males and last drops of urine in both sexes. [2] The deep transverse perineal muscle lies in the same plane as the urethral sphincter and formerly the two muscles were described together as the constrictor ...
Levator ani syndrome is a condition characterized by burning pain or tenesmus of the rectal or perineal area, [1] caused by spasm of the levator ani muscle. [2] [3] [4] The genesis of the syndrome is unknown; however, inflammation of the arcus tendon is a possible cause of levator ani syndrome. [5]
The middle fibers are inserted into the side of the rectum, blending with the fibers of the sphincter muscles; lastly in the male, the anterior fibers descend upon the side of the prostate to unite beneath it with the muscle of the opposite side, joining with the fibers of the external anal sphincter and transverse perineal muscles, at the ...
The anal triangle can be defined either by its vertices or its sides. Vertices. one vertex at the coccyx bone; the two ischial tuberosities of the pelvic bone; Sides. perineal membrane (posterior border of perineal membrane forms anterior border of anal triangle) the two sacrotuberous ligaments
Anal bleaching is a process in which the anus and perineum is lightened. Perineum sunning is a process in which the anus is sun tanned by deliberate exposure to sunlight, resulting in a darkening of the area. [21] A true anal piercing is rare because it may interfere with the function of the anus and cause infections. Surface piercings of the ...
In females, there is no union, nor a tendinous perineal raphe; the parts are disjoint primarily and arise from the same central tendinous point of the perineum, which is the tendon that is formed at the point where the bulbospongiosus muscle, superficial transverse perineal muscle, and external anal sphincter muscle converge to form this major ...
