Tendinous arch

At the level of a line extending from the lower part of the symphysis pubis to the spine of the ischium is a thickened whitish band in this upper layer of the diaphragmatic part of the pelvic fascia. It is termed the tendinous arch or white line of the pelvic fascia, and marks the line of attachment of the special fascia (pars endopelvina fasciæ pelvis) which is associated with the pelvic viscera.
