    • Embryo: Developmental stage of zygote from implantation to 5-8 weeks.
    • Fetus: Unborn child from the 8th week until term.
    • Term: Pregnancy duration when birth is expected, 37-42 weeks considered normal.
    • Abortion: Termination of pregnancy before 24 weeks; can be spontaneous or induced.
    • Stillbirth: Fetus born without life signs at or after 24 weeks.

    Key Pregnancy Terms

    • Gravida: Number of pregnancies a woman has had.
    • Para/Parity: Number of births after 24 weeks.
      • Nullipara: Never given birth.
      • Primipara: Delivered one child.
      • Multipara: Delivered more than one child.
      • Grand multipara: Delivered five or more children.
    • Trimester: One-third periods of pregnancy (1st: conception to 13w6d, 2nd: 14w to 27w6d, 3rd: 28w to delivery).
    • Gestational Age: Time of pregnancy measured from the last menstrual period.
    • Estimated Date of Confinement (EDC): Expected delivery date, averaging 280 days or 40 weeks.

    Anatomy of Uterus and Fetal Skull

    • The fetal skull comprises frontal, parietal, occipital, and temporal bones.
    • Sutures: Unossified membranes allowing flexibility during delivery.
      • Include frontal, coronal, sagittal, and lambdoid sutures.
    • Fontanelles: Non-ossified areas of the skull; anterior closes at 18 months, posterior at 6 weeks.
    • Clinical significance includes guiding vaginal exams and skull shape during labor.

    Umbilical Cord Characteristics

    • Connects the placenta to the fetus, approximately 50 cm long and 2 cm in diameter.
    • Contains two umbilical arteries (deoxygenated blood) and one umbilical vein (oxygenated blood).
    • Functions to transport nutrients and oxygen to the fetus and remove waste products for maternal excretion.
    • Common abnormalities include true knot and jelly cord.

    Placenta Exchange System

    • Consists of chorionic villi facilitating gas and nutrient exchange.
    • Fetal blood circulates through umbilical cord, interacting with maternal blood via diffusion and active transport.
