Where are the erectile locations in the relation to the urethra?

The erectile tissues associated with the penis, primarily the corpora cavernosa and the corpus spongiOSum, are located surrounding the urethra. The corpora cavernosa are situated on either side of the urethra, while the corpus spongiOSum, which contains the urethra, runs along the underside of the penis. This arrangement allows for the expansion and engorgement of these tissues during erection, facilitating sexual function.
