  1. Physical Development By. Constance Bates

  2. The Germinal Stage • Conception through two weeks • cell divisions occurring • fertilized egg embedding in the wall of the uterus • Amnion, placenta, and umbilical cord beginning to form

  3. The Embryonic Stage • 2 weeks through 8 weeks • The heart, liver, digestive system, brain, and lungs develop • tissue segments in a spinal column form • future arms and legs begin appearing • ears and eyes begin to form

  4. The Fetal Stage • 9 weeks • facial features form • limbs, hands, feet, fingers, and toes are developing • 12 weeks • 3 inches long and weigh about 1 ounce • muscles begin forming • teeth and vocal cords are developing • eyelids and nails start appearing

  5. The Fetal Stage • 16 weeks • the fetus is about 6 to 8 inches long and weigh about 5 to 6 ounces • cottony growth appears • heart beats can be heard by using a stethoscope • eyebrows and eyelashes begin growing • 20 weeks • the fetus is about 10 to 12 inches long and weigh about one pound • sweat glands form • head hair appears

  6. The Fetal Stage • vernixcaseosa covers the body • the skin begins to develop • 24 weeks • the fetus is about 14 inches long and weigh about 2 pounds • the eyes are mature • taste buds are developed • 28-40 weeks • growing rapidly • the lanugo disappears • fatty tissue forms • body organs mature

  7. Emotional Development • During pregnancy the mother and sometimes the father begins talking to the baby. The baby then begins to recognize voices and sounds. • Babies also begin to respond to voices, music and sounds by moving and kicking around. • If the mother has a less stressful emotion the baby will be a lot calmer and a lot happier. • Whatever the mother feels, the baby feels

  8. Cognitive Development • The brain begins to develop by the third week • By the fourth week, the brain develops into three sections; forebrain, middle brain and hind brain • By the sixth week the neural tube that connects the brain and spinal cord closes • By the tenth week the brain development is very rapid and is forming 250,000 neurons per minute. • By the nineteenth week the baby is able to make muscle movements. The forebrain develops into left and right cerebral hemispheres of the brain. • By the twenty second week the brain is understanding sensory perceptions and the fetus becomes capable of distinguishing between different sounds.

  9. Cognitive Development • By the twenty fourth week the brain starts regulating all body functions, and activating the auditory and visual systems. • By the twenty sixth week the brain enhances auditory and visual sensors. • By the twenty seventh week the baby may be able to dream. • By the twenty eighth week the brain is monitoring the breathing and regulating body temperature. • During the twenty ninth and fortieth week the brain will increase and grow extremely fast.
