Which muscles meet at the perineal body?

• A. Superficial and deep transverse perineal muscles, bulbospongiosus, external anal sphincter, pubococcygeus
• B. Bulbospongiosus and ischiocavernosus
• C. Levator ani and coccygeus
• D. Iliococcygeus and puborectalis

Answer: (A)

The perineal body is a central fibromuscular anchor in the midline of the perineum where several pelvic floor muscles converge to form a supportive node for the urogenital and anal openings. The muscles meeting there are the bulbospongiosus, the superficial and deep transverse perineal muscles, the external anal sphincter, and fibers of the pubococcygeus. This convergence helps stabilize the posterior border of the urogenital diaphragm and contributes to continence and pelvic support.

Other muscles in the region don’t all attach to this central point. The ischiocavernosus attaches to the ischiopubic rami and the crus of the penis or clitoris rather than to the perineal body. The iliococcygeus and puborectalis are parts of the levator ani that run along the pelvic walls and around the anorectal junction, not converging at the perineal body.
