Station
The level of the presenting part relative to maternal pubic symphysis on abdominal palpation or to the ischial spines on vaginal examination
Lie
The long axis of the foetus in relation to the long axis of the uterus (e.g. longitudinal, oblique, transverse)
Position
The relationship between a given bony landmark of the presenting part (‘denominator’) to the left or right of the mother’s anterior/posterior/transverse pelvis
Presentation
The portion of the foetal body that is foremost within the pelvic brim or in closest proximity to it.
If the presenting part is the foetal head, it is a cephalic presentation.
If the presenting part is the butt, it is a breech presentation.
If the foetal lie is transverse then the shoulder is the presenting part.
Asynclitism
The posture in which one parietal bone is at a lower level than the other due to lateral inclination of the head (side-to-side tilt of the head)
Caput
Oedema of the foetal scalp caused by pressure of its head by the cervix, obstructing venous return
