Pregnancy glossary A - Anencephaly to Amniotic sac

Anencephaly

This disorder is a neural tube defect and involves incomplete development of the brain, spinal cord, and/or their protective coverings. The neural tube is a narrow sheath that folds and closes between the 3rd and 4th weeks of pregnancy to form the brain, skull, and scalp. Infants with this disorder are born without both a forebrain (the front part of the brain) and a cerebrum (the thinking and coordinating area of the brain). The remaining brain tissue is often left exposed - not covered by bone or skin.

APGAR score

The APGAR score is a measurement of a newborn's response to the birth experience and its new life outside the womb.

The scoring is from 1-10, with 10 being very high.

The ratings are based on the following factors:

  • Appearance (color)
  • Pulse
  • Grimace (reflex)
  • Activity and Respiration

Abruptio placenta

This is the term given to the premature separation of a normally implanted placenta from the uterus and can be quite severe. Symptoms of placental abruption include bleeding, cramping, and abdominal/uterine tenderness.

This is the name given to the absence of your menstrual period - one of the first signs of pregnancy. After the birth of your baby you will experience amenorrhea from somewhere between 6 weeks and three months - usually longer if you are breastfeeding.
