When the bladder is distended, its lateral caudal margins are bordered by which structure?

When the bladder is distended, its lateral caudal margins are bordered by which structure?

• A. Acetabula
• B. Ischial spine
• C. Pubic symphysis
• D. Pelvic brim

Answer: (A)

When the bladder fills, it rises and its lower edges come to rest on the pelvic floor and the inner walls of the pelvic bones. The lateral borders of these inferior margins are against the hip sockets, the acetabula, on each side. The pubic symphysis lies at the front, the pelvic brim marks the upper boundary, and the ischial spine is more posteriorly located, not forming the lateral border of the inferior margins. So the acetabula are the structures that border the bladder’s lateral caudal margins when it’s distended.
