Which erectile tissues are covered by tunica albuginea?

• A. Corpus Cavernosa
• B. Corpus Spongiosum
• C. Both Corpus Cavernosa and Corpus Spongiosum
• D. Glans penis

Answer: (C)

Tunica albuginea is the fibrous capsule that surrounds erectile tissue and helps create rigidity during an erection. In the penis, there are two corpora cavernosa and one corpus spongiosum. The tunica albuginea envelops each corpus cavernosum, and it also covers the corpus spongiosum (though the coverage over the sponge is thinner). This encapsulation is what allows the erectile tissues to trap blood and become firm when aroused. The glans penis, on the other hand, is covered by mucosa and skin rather than this fibrous capsule, so it is not wrapped by tunica albuginea. So, both the corpora cavernosa and the corpus spongiosum are covered by tunica albuginea.
