The deep transverse perineal muscle (transversus perinei profundus) lies in the perineum, a part of the pelvic floor. It arises from the inferior rami of the ischium and runs to the median plane , where it interlaces in a tendinous raphe with the other deep transverse perineal muscle of the opposite side.
The muscles surrounded by the deep perineal fascia are the bulbospongiosus, ischiocavernosus, and superficial transverse perineal. The fascia is attached laterally to the ischiopubic rami and fused anteriorly with the suspensory ligament of the penis or clitoris.
Descending perineum syndrome (also known as levator plate sagging) [1] refers to a condition where the perineum "balloons" several centimeters below the bony outlet of the pelvis during strain, although this descent may happen without straining. [2]
For women, there is a 20.5% risk for having a surgical intervention related to stress urinary incontinence. The literature suggests that white women are at increased risk for stress urinary incontinence. [12] Though pelvic floor dysfunction is thought to more commonly affect women, 16% of men have been identified with pelvic floor dysfunction. [13]
Contains superficial perineal muscles: transversus perinei superficialis, bulbospongiosus, ischiocavernosus: Inferior fascia of urogenital diaphragm, or perineal membrane: A membranous layer of the deep fascia: Deep perineal pouch: Contains the deep perineal muscles: transversus perinei profundus, sphincter urethrae membranaceae
superficial transverse perinei; The perineum attaches across the gap between the inferior pubic rami bilaterally and the perineal body. This grouping of muscles constricts to close the urogenital openings. The perineum supports and functions as a sphincter at the opening of the vagina. Other structures exist below the perineum that support the ...
The perineal membrane has two distinct portions that span the opening of the anterior pelvic outlet. [2]The ventral (anterior) portion is associated with the compressor urethra and urethrovaginal sphincter muscles (previously called deep transverse perineal muscles), and is continuous with the insertion of the arcus tendineus fascia pelvis. [3]
Deep transverse perineal muscles; External sphincter muscle of male urethra; External sphincter muscle of female urethra; Compressor urethrae muscle in the female is sometimes included [3] Urethrovaginal sphincter in the female is sometimes included [3] other Membranous urethra in the male; proximal portion of urethra in the female ...
