Anatomical Structure and Location of the Crus of the Clitoris

Description

Centered within a partially sectioned bony pelvis, the uterus sits superior to the vaginal canal, with the uterine tubes extending laterally toward the ovaries and their suspensory attachments. Anterior and inferior in the urogenital region, the clitoral body continues proximally into paired crura (crura clitoridis), the posteriorly directed limbs of the corpora cavernosa that diverge laterally to anchor along the ischiopubic rami. Deep to the labia in the superficial perineal pouch, each crus lies medial to the inferior pubic ramus, converging toward the midline as it approaches the clitoral shaft. Blue ligamentous elements likely include the broad ligament (mesometrium, mesosalpinx) and ovarian ligament, framing the adnexa against the pelvic sidewall. Focusing on the crus matters because it is the fixed, deep erectile component of the clitoris and a key landmark for both sexual function and operative planning. During procedures such as Bartholin gland surgery, perineal repair after obstetric laceration, or vulvar oncologic resections, dissection near the ischiopubic ramus risks injury to the crura and adjacent dorsal neurovascular structures, with postoperative dyspareunia or altered arousal as real consequences. This view also helps clarify why blunt trauma to the perineum or aggressive instrumentation can produce deep hematoma tracking along the attached corpora cavernosa. Use this artwork to teach pelvic floor and perineal anatomy in gross anatomy, urogynecology, or sexual medicine modules, where learners often confuse the visible glans with the much larger internal erectile bodies. It also fits well in atlases and patient education materials that need an accurate, non-sensational representation of clitoral crura in relation to the uterus, vagina, and supporting ligaments.
