Early PhysicalDevelopment

Prenatal Development conception baby 1 single cell 100 trillion cells

EGG + SPERM = ZYGOTEDivides into about 100 cells within a week and then cells begin to differentiate

Terms used to describe the developing human:

• Zygote = fertilized egg• Embryo = 2-8 weeks (difficult to distinguish

human from other mammals at this time)

• Fetus = 9 weeks to birth• Neonate = newborn• Infant = from the first

few days until walking

TeratogensHarmful things such as chemicals or diseases that can reach the developing embryo or fetus and cause damage resulting in birth defects or mental retardation.

Effect of Nicotine on a fetus- increased risk of abnormal fetal heartbeat, premature birth, related complications and miscarriage.

Effects of Alcohol on a fetus- Mothers who drink heavily during pregnancy may have children born with Fetal Alcohol Syndrome (FAS)• Physical and cognitive abnormalities• Brain damage• Facial misproportions:• Small upturned nose, small jaw, small eyes

"Teratogens and Their Effect on the Developing Brain"

Infancy• Physical growth rate is faster than any other

postnatal period.• Maturation = physical growth and

development of the body and especially the nervous system.

• Rate varies, but order is virtually universal!

IMPORTANT: Maturation often creates a condition of readiness for learning.

WHAT DOES THAT MEAN? (and why does it matter?)

The Newborn• Reflexes- an automatic,

unlearned response– Sucking– Swallowing– Grasping

Temperament- emotional excitability

Easy DifficultSlow to warm-up

Newborn Reflexes• Reflexes that are seen in the newborn indicate

that the nervous system is up and running.– Rooting reflex = looking for food– Grasping reflex = hanging on– Sucking reflex = receiving nourishment– Moro reflex = startle reflex
