Buck’s Fascia

ANATOMY Buck’s fascia

In the penis, the erectile bodies are surrounded by Buck’s fascia, dartos fascia, and skin.

Buck’s fascia is the tough, elastic layer immediately adjacent to the tunica albuginea.

On the superior aspect of the corpora cavernosa, the deep dorsal vein, paired dorsal arteries, and multiple branches of the dorsal nerves are contained within the envelope of Buck’s fascia.

In the midline groove on the underside of the corpora cavernosa, Buck’s fascia splits to surround the corpus spongiosum.

Consolidation of the fascial layers, lateral to the corpus spongiosum, attaches it to the tunica albuginea of the corpora cavernosa.

Attached distally to the undersurface of the glans penis at the corona, Buck’s fascia extends into the perineum, enclosing each crus of the corpora cavernosa and the bulb of the corpus spongiosum and firmly fixing these structures to the pubis, ischium, and inferior fascia of the perineal membrane (urogenital diaphragm)
