Which description best captures the location of the perineal body relative to the vaginal vestibule and anal canal?

• A. Lateral to both
• B. Anterior to vaginal vestibule and posterior to anal canal
• C. Superior to vaginal vestibule and inferior to anal canal
• D. Posterior to vaginal vestibule and anterior to anal canal

Answer: (D)

The perineal body is the central tendon in the midline of the perineum where several perineal muscles converge. It sits between the vaginal vestibule (in front) and the anal canal (behind), so it is posterior to the vaginal vestibule and anterior to the anal canal. This location also marks the boundary between the urogenital and anal triangles and serves as an attachment point for muscles of both regions.
