The dome shaped widest portion of the uterus is called what?

• A. Fundus
• B. Cornua
• C. Isthmus
• D. Body

Answer: (A)

The dome-shaped widest part is the fundus. It sits at the top of the uterus and forms a rounded, convex upper portion that is wider than the rest of the organ. The openings of the fallopian tubes are located near the fundus, which helps define its position as the superior boundary of the uterine cavity. By contrast, the body is the main central portion below the fundus, the isthmus is the narrow segment toward the cervix, and the cornua are the horn-like regions where the tubes connect. Because the top of the uterus bulges outward into a dome, the fundus is the dome-shaped, widest part. In ultrasound practice, this landmark is also used when assessing uterine and pregnancy-related measurements.
