Deep Space Nine (1993â1999) Star Trek: Deep Space Nine is also sometimes called DS9. It is set in the late 24th century, at the end of The Next Generation's time line and the start of Voyager's. It is not like TOS and TNG because it is set on a space station and is not about exploring.
The corpus spongiosum is the mass of spongy tissue surrounding the male urethra within the penis. Also called the corpus cavernous urethrae in older texts.
The penis contains two chambers, the corpora cavernosa, which run the length of the organ. These chambers are filled with spongy tissue and surrounded by a membrane called the tunica albuginea. The spongy tissue contains smooth muscles, fibrous tissues, spaces, veins, and arteries.
