THORAX ABDOMEN AND PELVIS

Detailed explanation-1: -The corpus cavernosum is the erectile tissue of your penis, along with the corpus spongiosum. The corpus spongiosum has also been called the corpus cavernosum urethrae. The corpus spongiosum surrounds the urethra. There is a corpus cavernosum on either side of your ureter.

Detailed explanation-2: -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-3: -The tunica albuginea forms a thick fibrous coat to the spongy tissue of the corpora cavernosa and corpus spongiosum. It consists of two layers, the outer longitudinal and the inner circular. The tunica albuginea becomes thicker centrally where it forms a groove to accommodate the corpus spongiosum.

Detailed explanation-4: -The membranous urethra is enveloped by cavernous tissue and the urethralis muscle. The penile urethra extends from the ischial arch to the tip of the penis. This part of the urethra is also known as the cavernous urethra because the majority of it is encased by erectile tissues of the penis.
