Study Notes
Labor and Fetal Presentation
- Definition of Labor: The process by which the uterus contracts to move the fetus down the birth canal.
Vertex Presentation
- Lie in Vertex Presentation: The fetus's longitudinal axis is in line with the mother's longitudinal axis.
- Attitude Denominator in Vertex Presentation: The fetus's spine is flexed, with the chin tucked to the chest.
Station System
- Range of the Station System: A system measuring the progress of the fetus's head during labor, ranging from -3 to +3, with -3 being the highest point and +3 being the lowest point in the birth canal.
Uterine Contractions
- Uterine Contractions: Periodic, involuntary contractions of the uterus that help move the fetus down the birth canal during labor, considered a natural process to facilitate childbirth.
