After teaching a group of students about the maternal bony pelvis, which statement by the group indicates that the teaching was successful?
A) The bony pelvis plays a lesser role during labor than soft tissue.
B) The pelvic outlet is associated with the true pelvis.
C) The false pelvis lies below the imaginary linea terminalis.
D) The false pelvis is the passageway through which the fetus travels.
B
Feedback:
The maternal bony pelvis consists of the true and false portions. The true pelvis is made up of three planes—the inlet, the mid pelvis, and the outlet. The bony pelvis is the more important part of the passageway because it is relatively unyielding. The false pelvis lies above the imaginary linea terminalis. The true pelvis is the bony passageway through which the fetus must travel.
