LIFE INFORMATION 
What happens after conception?

First of all conception occurs when the father's sperm penetrates the mother's egg cell.   Genetic instructions from parents interact to begin a new and unique individual - no bigger than a grain of sugar.

Then the following things happen:

1st. day:  The first cell divides into two, the two into four, and so on.

5-9 days:  The new person burrows into the wall of the womb. At this point the gender can be determined.

14 days:  Mothers's menstrual period is supressed by a hormone produced by her baby.

18 days:  Heart is forming; eyes developing.

20 days:  Foundations of brain, spinal cord and nervous system are laid.

24 days:  Heart begins to beat.

28 days:  Muscles are developing along the future spine.  Arms and legs are budding.

30 days:  Baby has grown 10,000 times to 6-7mm. (1/4 in.) long.  Brain has human proportions.  Blood flows in veins (but stays separate from mother's blood).

35 days:  Pituitary gland in brain is forming.  Mouth, ears and nose are taking shape.

40 days:  Heart's energy output is 20% of adult's.

42 days:  Skeleton is formed.  Brain coordinates movement of muscles and organs.  Reflex responses have begun.

43 days:  Brain waves can be recorded.

45 days:  Spontaneous movements have begun.  Buds of milk teeth have appeared.

7 Weeks:  Lips are sensitive to touch.  Ears may resemble family pattern.

8 Weeks:  Baby is well-proportioned, small-scale baby, 3cm. (1 1/8 in.) sitting up and a gram (1/30 oz.) in weight.  Every organ is present.  Heart beats sturdily.  Stomach produces digestive juices.  Liver makes blood cells.  Kidneys begin to function.  Taste buds are forming.

9 Weeks: Baby will bend fingers around an object placed in the palm.  Thumb sucking occurs.  Fingernails are forming.

10 Weeks:  Body is sensitive to touch.  Baby squints, swallows and frowns.

11 Weeks:  Baby urinates, makes complex facial expressions - even smiles.

12 Weeks:  Vigorous activity shows distinct individuality.  Baby can kick, turn feet, curl and fan toes, make a fist, move thumbs, bend wrists, turn head, open mouth and press lips tightly together.  Breathing is practiced.

13 Weeks:  Face is prettier, facial expressions resembling parents.  Movements are graceful.  Vocal cords are formed (but without air baby cannot cry).  Sex organs are apparent.

4 Months:  Baby can grasp with hands, swim and turn somersaults.

4 - 5 Months:  Mother senses movements.

5 Months:  Sleeping habits appear.  Baby responds to sounds in frequencies too high or low for adults to hear.

6 Months:  Fine hair grows on eyebrows and head.  Eyelash fringe appears.  Weight is about 640g. (1 lb. 6 oz.) and height 23 cm. (9 in.). Babies born at this age have survived.

7 Months:  Eye teeth are present.  Eyelids open and close, eyes look around.  Hands grip strongly.  Mother's voice is recognized.

8 Months:  Weight increases by 1Kg. (over 2 lbs.) and baby's quarters get cramped.

9 Months:  Baby triggers labor and birth occurs, usually 255-275 days after conception.  Of 45 generations of cell divisions before adulthood, 41 have already taken place.
