Which of the following structures is NOT part of the true pelvis?

The fundus is the uppermost part of the uterus during pregnancy and is not considered a part of the true pelvis. The true pelvis, often referred to as the "lesser pelvis," includes the inlet, cavity, and outlet, which are anatomical spaces relevant for childbirth.

• The inlet refers to the upper opening of the true pelvis, where the fetal head enters during labor.

• The cavity of the true pelvis is the space within which the fetus descends during delivery.

• The outlet is the lower border of the true pelvis, marking the exit route for the baby during childbirth.

In contrast, the fundus is not associated with pelvic anatomy pertinent to delivery; rather, it pertains to uterine structure and function. Understanding these distinctions is crucial for those studying midwifery and obstetrics, as they relate directly to childbirth mechanics and the anatomical considerations of the birth process.
