(Top) Coronal view shows the pelvic floor at the level of the vagina. The levator ani muscles form the pelvic floor through which the
urethra, vagina, and rectum pass, and are the main support for the pelvic organs. The deep transverse perineal muscle and fascia, along
with the urethral sphincter, form the urogenital diaphragm, which is the main support of the lower vagina. (Bottom) Frontal graphic
shows the iliac vessels. The internal iliac artery divides into an anterior trunk and posterior trunk. The VA can branch off directly from
the anterior trunk of the internal iliac artery or sometimes from the inferior vesical artery or UA. The arterial supply of the vagina
includes the VA and vaginal branch of the descending trunk of UA.
