Crus of the Clitoris

Description

Seen from the anterior pelvis, the paired crura clitoridis (proximal corpora cavernosa) diverge laterally from the midline body of the clitoris and run posteriorly and laterally along the ischiopubic rami. Each crus anchors to the periosteum of the inferior pubic ramus and ischial ramus, deep to the overlying ischiocavernosus muscle, while the vestibular bulbs lie more medial and inferior along the vaginal vestibule. Superiorly, the pubic symphysis and arcuate pubic ligament relate to the clitoral body, and the uterus, uterine tubes, and ovaries sit more cranial within the lesser pelvis, framed by the os coxae. Color coding differentiates arteries from veins. For teaching female sexual anatomy, the crura are the key to understanding why clitoral erectile tissue extends well beyond the visible glans and why fixation to the ischiopubic rami matters during engorgement. This relationship also underpins operative safety: dissection near the ischiopubic ramus, the anterior vaginal wall, or along the pubic arch risks injury to the dorsal nerve of the clitoris and the internal pudendal vascular branches that supply the corpora cavernosa. A small field. High stakes. Use this illustration in pelvic anatomy and sexual medicine modules, in gynecologic and urogynecologic surgical texts discussing anterior compartment approaches, and in patient education materials addressing clitoral anatomy in the context of dyspareunia, vulvar pain syndromes, or post-traumatic scarring. It also pairs well with cadaver lab guides that distinguish clitoral crura from vestibular bulbs and nearby pelvic vasculature. Anatomical accuracy verified by SciePro's Medical Advisory Board.
