 The parts of the clitoris inside the body include erectile tissue, glands, muscles, blood vessels, and nerves. In both the clitoris and the penis, there are two types of erectile tissue. These are "corpus cavernosum" (cavern-like body) and vestibular bulbs. These tissues fill with blood during sexual arousal. This causes an erection. The clitoral shaft is connected to the glans. It is just underneath the surface of the skin. The shaft is a round spongy erectile tissue. It is very sensitive like the glans. It feels like a hard ridge. The shaft is about long. It moves toward the pubic mound for a short distance, then bends sharply and divides. This forms two thin legs. These legs are also made of spongy tissue. The legs spread out like the wishbone of a chicken.
