The Corpus Spongiosum and Cavernosum are Erectile Tissue in the Penis

Question

The corpus spongiosum and cavernosum are erectile tissue in the penis.

Accepted Answer

The corpus spongiosum and cavernosum are both types of erectile tissue in the penis. The corpus spongiosum surrounds the urethra and helps to maintain its patency during an erection, while the two corpora cavernosa are located on either side of the spongiosum and fill with blood during an erection to create rigidity.
