Which structure is contained in the deep perineal space?

• A. Membranous part of the urethra
• B. Root of penis
• C. Bulbospongiosus muscle
• D. Part of vagina

Answer: (A)

The deep perineal space (pouch) contains structures that pass through the urogenital diaphragm and are nestled around the urethra. The membranous part of the urethra travels through this space as it transitions from the prostatic urethra to the penile urethra, and it is surrounded by the external urethral sphincter within this compartment. This makes it the structure you’d expect to find in the deep pouch. The root of the penis and the bulbospongiosus muscle reside in the superficial perineal pouch, not the deep one, and the vagina is not a constituent of the deep perineal space.
