Locating cervix and uterus in female reproductive diagram

Steps:

• Recall cervix as narrow neck of uterus connecting to vagina, positioned inferiorly.
• Identify uterus as pear-shaped muscular organ superior to cervix.
• Scan labels: 4 marks lower narrow structure (cervix); 3 marks broader upper organ (uterus).
• Match to options: D assigns cervix to 4, uterus to 3.

Why D is correct:

• Cervix is defined as inferior uterine portion; label 4 aligns below uterine body at 3 per anatomical position.

Why the others are wrong:

• A mislabels upper structures (1,2) as cervix/uterus, likely ovaries or tubes.
• B swaps labels 1 and 2, inverting superior-inferior anatomy.
• C reverses 3 and 4, assigning broader uterus label to cervix.

Final answer: D
