corpus cavernosum penis
Quick Summary
The corpus cavernosum is one of three cylindrical masses of erectile tissue within the penis. These tissues are bound together by fibrous material. The two corpora cavernosa run along the sides of the penis, while the corpus spongiosum lies beneath them, surrounding the urethra and forming the glans penis.
During an erection, blood flows into the spongy spaces within these tissues, causing them to enlarge and harden. This process is triggered by physical or psychological stimulation. The arteries supplying blood to the penis dilate, increasing blood flow, while the veins that drain blood from the penis are compressed, temporarily trapping blood and maintaining the erection. The corpus spongiosum, which contains the urethra, does not become as rigid as the corpora cavernosa to allow for semen release.12
