GENERAL HISTOLOGY

Detailed explanation-1: -The corpus spongiosum surrounds the urethra (the tube through which urine and sperm pass from the body). It contains blood vessels that fill with blood to help make an erection and keep the urethra open during the erection.

Detailed explanation-2: -The paired corpora cavernosa contain erectile tissue and are each surrounded by the tunica albuginea, a dense fibrous sheath of connective tissue with relatively few elastic fibers. The corpora cavernosa communicate freely through an incomplete midline septum.

Detailed explanation-3: -In male anatomy, the corpus spongiosum of penis is a mass of erectile tissue that lies along the underside of the penis and is located below the pair of corpus cavernosa, which contain 90 percent of the blood volume during a normal erection.

Detailed explanation-4: -The corpus spongiosum is the mass of spongy tissue surrounding the male urethra within the penis. It is also called the corpus cavernosum urethrae in older texts.

Detailed explanation-5: -The corpora cavernosa are paired spongy cylinders that lie on the superior aspect of the penis. They are enveloped by the tunica albuginea.
