B- Delivery of the Shoulders and Body:

The biacromial diameter descends in the opposite oblique diameter of the pelvis. The

anterior shoulder meets the pelvic floor first and rotates forwards one-eighth of a circle

with further descent, the anterior shoulder appears below the symphysis pubis. The

posterior shoulder is delivered first by lateral flexion of the fetal spine then the anterior

shoulder follows. Finally, the trunk is delivered by lateral flexion of the spine around

the symphysis pubis.
