Inside, two cylinder-shaped chambers called the Corpora Cavernosa run the length of through, runs along the underside of them, in the spongy tissue of the Corpus Spongiosum. Two main arteries (one in each of the Corpora Cavernosa) and several veins move blood in and out. Nerves relay messages to and from other parts of the body.
