What is a dome-shaped portion superior to the uterine tubes called?

Appeared in: BTSC 3 August 2025

Explanation

The fundus is the correct anatomical term for the rounded, dome-shaped upper part of the uterus.
It is located superior to (above) the line connecting the entry points of the two uterine (fallopian) tubes.
This specific location and shape are key identifiers for the fundus.

Option B: The cervix is the lower, narrow, cylindrical part of the uterus that connects to the vagina, not the upper dome-shaped portion.
Option C: The isthmus is the narrow, constricted segment located between the body of the uterus and the cervix. It is not the superior, dome-shaped part.
Option D: The body (or corpus) is the main, central part of the uterus, but the fundus is the specific term for the uppermost dome-shaped region.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Anatomy of the Uterus as background academic context rather than a clinical decision trigger.
Measuring fundal height is a standard nursing practice during pregnancy to assess fetal growth and gestational age. The measurement is taken from the top of the pubic bone to the top of the fundus.
After childbirth, nurses assess the fundus to ensure it is firm and contracting properly to prevent postpartum hemorrhage. A boggy (soft) fundus requires immediate intervention, such as fundal massage.
What if? If a pregnant patient's fundal height measures significantly smaller than expected for her gestational age, it could indicate issues like intrauterine growth restriction (IUGR), oligohydramnios (low amniotic fluid), or an error in dating the pregnancy, requiring further investigation.

How to Approach the Question

This is a factual recall question testing knowledge of female reproductive anatomy.
First, read the question carefully to identify the key descriptors: 'dome-shaped portion', 'superior', and 'uterine tubes'.
Mentally visualize the structure of the uterus.
Evaluate each option based on the anatomical definition.
The 'fundus' is defined as the dome-shaped top of the uterus, located above the fallopian tubes.
The 'cervix' is the bottom, 'isthmus' is the constriction, and 'body' is the main part. Therefore, 'fundus' is the only option that matches the description.
