PATHOLOGY

Detailed explanation-1: -One of two columns of spongy tissue that runs through the shaft (body) of the penis . The corpus cavernosum forms most of the penis and contains blood vessels that fill with blood to help make an erection.

Detailed explanation-2: -On the dorsal aspect of the corpora cavernosa, the deep dorsal vein and paired dorsal arteries and branches of the dorsal nerves are contained within the deep penile (Buck) fascia.

Detailed explanation-3: -The crural (roots) of the corpora cavernosa attach at the under surface of the ischiopubic rami as two separate structures. Such anatomy prevents the erect penis from sinking into the perineum when faced with an axially-oriented vaginal compressive load during intercourse.
