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 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 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 ...
Older texts have asserted the existence of a urogenital diaphragm, also called the triangular ligament, which was described as a layer of the pelvis that separates the deep perineal sac from the upper pelvis, lying between the inferior fascia of the urogenital diaphragm (perineal membrane) and superior fascia of the urogenital diaphragm.
Age, pregnancy, family history, and hormonal status all contribute to the development of pelvic organ prolapse. The vagina is suspended by attachments to the perineum, pelvic side wall and sacrum via attachments that include collagen, elastin, and smooth muscle. Surgery can be performed to repair pelvic floor muscles.

He was the first physician to describe the transverse perineal ligament, sometimes referred to as "Krause's ligament". He also described the accessory tear glands of the eye. These glands are found under the eyelids where the lower and upper conjunctiva meet, and are sometimes known as " Krause's glands ".
