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 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.

The cardinal ligament (also transverse cervical ligament, lateral cervical ligament, [1] or Mackenrodt's ligament [2] [1]) is a major ligament of the uterus formed as a thickening of connective tissue of the base of the broad ligament of the uterus. It extends laterally (on either side) from the cervix and vaginal fornix to attach onto the ...
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 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.
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 perineal artery (superficial perineal artery) arises from the internal pudendal artery, and turns upward, crossing either over or under the superficial transverse perineal muscle, and runs forward, parallel to the pubic arch, in the interspace between the bulbospongiosus and ischiocavernosus muscles, both of which it supplies, and finally divides into several posterior scrotal branches ...
Scarpa's fascia ends inferior to the inguinal ligament fusing with the fascia lata of the thigh. In the midline, just superior to the penis, Scarpa's fascia contributes to formation of the fundiform ligament of the penis. As Scarpa's fascia continues posteriorly onto the perineum, it is called Colles' fascia. [3]
