A female homologue of the male penis , the clitoris develops as does the penis from the genital tubercle of the fetus, and it plays an important role in female sexual response. The body of the clitoris is suspended from the pubic bone by a short ligament and emerges to form a tiny external glans at the top of the vulva. Lying over the glans is a sheath of skin known as the clitoral hood. Extending internally from the glans is the shaft, or body, of the clitoris, a small cylinder about 2 to 3 cm about 0. From the body extend the erectile corpora cavernosa and bulbs.
