Question at position 8 The urinary bladder is in the _________ region.left iliachypogastricright iliacepigastricumbilical

BlackTom AI · Accepted Answer

The urinary bladder lies in the hypogastric (pubic or suprapubic) region — the central lower part of the anterior abdominal/pelvic wall.

1. Relevant knowledge points and concepts
- The nine-region abdominal scheme divides the abdomen into: right and left hypochondriac, epigastric, right and left lumbar (or lateral/flank), umbilical, right and left iliac (inguinal), and hypogastric (pubic) regions.
- The urinary bladder is an organ of the pelvic cavity, located posterior to the pubic symphysis and inferior to the anterior abdominal wall. When moderately empty it is entirely pelvic; when distended it can project into the hypogastric region.

2. Step-by-step reasoning
- Identify the bladder’s anatomical seat: central and low in the anterior pelvis, just behind the pubic bone.
- Locate that position on the nine-region map: centrally below the umbilical region and between the left and right iliac (inguinal) regions — this is the hypogastric (pubic) region.

3. Intermediate steps (spatial relations shown)
- Superior to the bladder: umbilical region.
- Lateral to the bladder: left and right iliac (inguinal) regions.
- Anterior to the bladder: pubic symphysis and abdominal wall.
- Therefore its regional label = hypogastric.

4. Why the correct answer is correct
- The hypogastric region literally denotes the area inferior to the stomach/umbilicus and central over the pubic area, matching the bladder’s midline, low pelvic position. Clinical and anatomical texts routinely describe the bladder as occupying the hypogastric (suprapubic) region.

5. Why other options are incorrect
- Left iliac/right iliac: lateral lower regions (contain sigmoid colon, appendix/cecum) — bladder is midline, not lateral.
- Epigastric: upper central region (above stomach area) — too superior.
- Umbilical: central around the navel — bladder lies inferior to this.

6. Conclusion
The bladder’s anatomical position corresponds to the hypogastric (pubic) region. This matches the provided answer: hypogastric.
