Body of penis

The corpora cavernosa are intimately bound to one another with a dorsally fenestrated septum, which becomes a complete one before the penile crura.

The body is surrounded by a bi-layered model of tunica albuginea in which a distal ligament buttresses the glans penis and plays an integral role to the penile fibroskeleton, and the structure is called "os analog", a term coined by Geng Long Hsu in the Encyclopedia of Reproduction.

[3] This indispensable structure is a continuation of the body of the human penis, differing from other mammalian penises, in that it has no baculum (or erectile bone) and instead relies exclusively on engorgement with blood to reach its erect state.

[8] A shallow groove, which marks their junction on the upper surface lodges the deep dorsal vein of the penis, which is flanked by a pair of cavernosal veins of the penis,[3] while a deeper and wider groove between them on the surface below contains the corpus spongiosum.
