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.
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 ...
Perineal tears mainly occur in women as a result of vaginal childbirth, which strains the perineum. It is the most common form of obstetric injury. [1] Tears vary widely in severity. The majority are superficial and may require no treatment, but severe tears can cause significant bleeding, long-term pain or dysfunction.
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 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.

Female pelvic muscles Male pelvic muscles. The pelvic floor or pelvic diaphragm is an anatomical location in the human body, [1] which has an important role in urinary and anal continence, sexual function and support of the pelvic organs. [2]
