The human penis is an external male intromittent organ that additionally serves as the urinal duct. The main parts are the root radix ; the body corpus ; and the epithelium of the penis including the shaft skin and the foreskin prepuce covering the glans penis. The body of the penis is made up of three columns of tissue : two corpora cavernosa on the dorsal side and corpus spongiosum between them on the ventral side.
The penis is composed of three cylinders encased in a sheath called the bucks fascia. These three cylinders are the corpus spongiosum and two corpora cavernosa known as the corpus cavernosum of penis. The corpus cavernosum contains spongy erectile tissue.
