  • 300 bones
  • 70+ reflexes
  • age of viability = somewhere about 6 months pregnant, fetus can survive if born
  • alcohol-related neurodevelopmental disorder (ARND) = alcohol-related developmental disabilities
  • amnion = fluid-filled sac that holds developing fetus
  • anoxia = low oxygen; potential cause of brain damage during delivery
  • Apgar Scale = evaluation of newborns on complexion, pulse, reflexes, activity & respiration
  • blastocyst
  • blastula
  • breech position = non-head-first birth (buttocks or feet)
  • cancer
  • cervix
  • cesarean delivery = surgical delivery of babies through abdominal wall, typically in distress
  • chorion = outermost layer of an embryo, developed by follicle cells of ovary
  • chromosomes
  • cilia
  • cleavage
  • corpus luteum
  • DNA
  • egg
  • ejaculatation
  • embryo = first 8 weeks of prenatal development
  • embryo stage
  • enzymes
  • expected date of delivery
  • expel
  • fallopian tube
  • fallopian tube contractions
  • female sex cells
  • fertilization
  • fertilized egg
  • fetal alcohol spectrum disorder (FASD) = continuum of disorders cause by prenatal alcohol exposure
  • fetal alcohol syndrome (FAS) = prenatal exposure to alcohol, leading cause of mental retardation
  • fetal monitors = monitors fetal heart rate & mother’s uterine contractions
  • fetal stage
  • fetus = from week 8-40 of prenatal development
  • fimbria
  • follicle
  • fraternal twins
  • FSH (folicle stimulating)
  • full term
  • germinal stage
  • hCG (human chorionic gonadotrophin)
  • hormones
  • human placental lactogen (HPL)
  • implantation
  • infant mortality = death of infant under 1 year old
  • inflammation
  • irregular ovulation
  • lanugo = soft fine hair on fetus, normally disappears before birth
  • last menses period (LMP)
  • LH (luteinizing hormone)
  • ligaments
  • menstrual period
  • morula
  • natural childbirth (prepared) = 1930’s movement, noninvasive methods to reduce delivery pain
  • Neonatal Behavioral Assessment Scale (NBAS) = test for infant 3 days to 4 weeks, checklist
  • neural tube = develops into spinal cord and brain
  • non-rapid-eye-movement (NREM) sleep = 3 sleep stages that precede REM
  • ova (plural)
  • ovarian stem cells
  • ovaries
  • ovulation
  • ovum
  • partial fetal alcohol syndrome (p-FAS) = prenatal alcohol exposure: CNS damage & growth deficiency
  • placenta = organ that filters mother’s blood supply for developing fetus
  • preterm infants
  • progesterone
  • rapid-eye-movement (REM) sleep = stage of sleep that includes vivid dreams & sleep paralysis
  • reflex = smallest amount of behavior, sensory neuron goes to spinal cord & triggers motor neuron
  • Rh factor incompatibility = can be a problem in delivery with fetus & mother’s blood come in contact
  • scar tissue & cysts
  • small-for-date infants = below 10th percentile in weight
  • sperm
  • sperm head
  • sperm middle
  • sperm tail
  • states of arousal = levels of consciousness, including sleep
  • sudden infant death syndrome (SIDS) = unexpected death of infant under age 1
  • surfactant
  • teratogen = any substance that interferes with embryo development
  • testicles
  • trimesters = 40 weeks of pregnancy divided into 3 sections
  • trophoblast
  • tubal ectopic pregnancy
  • umbilical cord = connects fetus and placenta
  • unfertilized egg
  • uterine contractions
  • uterus
  • vagina
  • vernix = vernix caseosa, white coating on newborn’s skin, waxy texture
  • viability
  • visual acuity = clearness, focus; newborn have limited vision
  • XX
  • XY
  • zygote
