This document discusses fetal positioning within the uterus including lie, presentation, attitude, and position. It notes that the longitudinal lie is most common with the fetus' long axis aligned with the long axis of the uterus. The cephalic presentation, where the head is positioned to descend through the birth canal, is also most frequent. It describes the typical fetal attitude as one with the head flexed, arms and legs flexed in front, and back curved forward to navigate the uterus and pelvis. Moulding or molding of the fetal skull to fit through the birth canal is also mentioned.
