What is a single footing breech?
Butt down with one leg exposed

Long axis of fetus is parallel to long axis of mother
What is a transverse fetal lie?
Long axis of fetus is perpendicular
What is an oblique fetal lie?
Fetal lie is at an angle between transverse and longitudinal lie
What is fetal attitude?
, Relationship of fetal head to its spine
What is complete flexion?
