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 .
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
The superficial perineal pouch is an open compartment, due to the fact that anteriorly, the space communicates freely with the potential space lying between the superficial fascia of the anterior abdominal wall and the anterior abdominal muscles:
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 ...

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 ...
