The clitoris is an erectile organ located where the labia minora meet anteriorly. The clitoris consists of a root and a small, cylindrical body, which are composed of two crura, two corpora cavernosa, and the glans clitoris. The crura attach to the inferior pubic rami and perineal membrane, deep to the labia. The body of the clitoris is covered by the prepuce. Together, the body and glans clitoris are approximately 2 cm in length and <1 cm in diameter.

In contrast to the penis, the clitoris is not functionally related to the urethra or to urination. It functions solely as an organ of sexual arousal. The clitoris is highly sensitive and enlarges on tactile stimulation. The glans clitoris is the most highly innervated part of the clitoris and is densely supplied with sensory endings.
