Which structure is a content of the superficial perineal space?

• A. Root of penis
• B. Bulbourethral gland
• C. Bulbospongiosus muscle
• D. Dorsal nerve of penis

Answer: (A)

The superficial perineal space (pouch) in males contains the proximal, anchoring part of the penis—the root. This region includes the bulb and the two crura of the penis, which sit within the superficial fascia and are wrapped by erectile tissue and surrounding muscles as they attach to the perineal body. Because the root is the defining proximal structure that occupies this space, it is the correct choice for a content of the superficial perineal space. Bulbourethral glands lie in the deep perineal pouch, not the superficial one. The dorsal nerve of the penis runs along the dorsum of the penis and is associated with vessels in the deep perineal region rather than the superficial pouch. (The bulbospongiosus muscle is a superficial perineal muscle and is closely associated with the root, but the root itself is the clearest, defining content of the superficial space.)
