The corpus spongiosum of the penis is surrounded by a tunica albuginea that is not as dense as that surrounding the corpora cavernosa. The urethra and its associated glands of Littre are visible in the center of the image. 100x

- Urethra >
The male urethra in the penis, the penile urethra, is typically lined by a pseudostratified epithelium; however, several different epithelial types occur throughout the length of the urethra.
- Glands of Littre >
Mucus-secreting glands of Littre empty into the urethra throughout its length. These glands produce the first portion of the ejaculate and aid in lubrication during intercourse.
- Cavernous spaces >
Cavernous spaces are visible in the corpus spongiosum. Some of these spaces are filled with blood and are, therefore, easy to identify at this magnification; more spaces are present but are more difficult to differentiate because they lacked blood at the time the tissue was removed.
