The clitoral crura are two erectile tissue structures which form a V-shape that meets at the clitoral body. They generally point towards the thighs, but when a woman is aroused, the crura, like all of the clitoris’ erectile tissue, becomes engorged with blood and stretches back towards the spine.
The crura are located next to the vestibular bulbs and attached to the pubic arch. The crura also run behind the labia for about four inches, along the urethra, the urethral sponge, and the vagina.
The ischiocavernosus muscle is also part of the clitoral crura. This muscle helps flex the anus and tense the vagina during the female orgasm. It is also one of the muscles worked during Kegel exercises.
