The trabeculae of corpus spongiosum of penis are the numerous fibrous and elastic bands dividing the corpus spongiosum penis into irregular compartments, giving the entire structure a spongy appearance.
The trabeculae of corpus spongiosum of penis are more delicate, nearly uniform in size, and the meshes between them smaller than in the corpora cavernosa penis: their long diameters, for the most part, corresponding with that of the penis.
The aforementioned compartments fill with blood during a penile erection.
