Clitoris

The clitoris is the female phallus or sex organ, and consists of the left and right corpus cavernosa  erectile tissues where they are fused along the midline.  The left and right crus of the clitoris are made up of  both the corpus cavernosa erectile tissue and the ischiocavernosus muscle.  The clitoris is the fused left and right corpus cavernosa erectile tissue, but the ischiocavernosus muscle does not extend into the clitoris.
