To establish it easier to the hang of its heart, it is recommendable to acquaint readers with the anatomy of a penile erection.
This is a complex establishment of two corpora cavernosa and tissue resembling a sponge in structure. In the center of the sponge, in each corpus cavernosum, there are arteries with uncountable branches that unveil into the cells of the sponge (sinuses). The cavernous bodies talk with with each other, as if fused with the inner sides, and the blood has the wit to flow from one to the other.
Each corpus cavernosum is resolved to the pubic bone of the pelvis, forming the legs of the penis. The corpora cavernosa are surrounded past a tunica albuginea that fuses with the spongy tissue.
The technique of developing an erection of the penis is simplified as follows: during propagative arousal, signals are sent from the essential upset system to the arteries that pass fundamentally the corpora cavernosa.
Thus, a amicable of closed hydrodynamic set-up is created.
They dilate, and a immense amount of blood abruptly fills the cells of the spongy tissue.
At the unmodified hour, the muscles, having received signals, about to covenant, squash the veins coming revealed of the legs of the cavernous bodies of the penis. The outflow of blood from the corpora cavernosa is strictly limited.
