gerimal stage
The germinal starts with conception, where the sperm begins making a journey down the fallopian tube to the uterus where it begins the cell reproduction. Starts with one cell then devlopes into two, then four and so on. After that is done it attaches itself to the wall where it wil begin the embryonic stage. it never properly attaches itself to the wall and so the new life dies before the mother is even aware. This stage goes on for two weeks at the most. this domain is physical -
outer cells
This is when the outer cells will eventually become the plecenta and the inner cells form the embryo. the next step is for the outer cells to implant themselves into the uterus, thats when they rupture tiny vessels. this domain is physical -
Period: to
prenatal development
-
three stages
the cell division continues at a rapid rate and the cells develop into a blastocyst. The blastocyst is made up of three laters:The ectoderm: which will become the skin and nervous system.The endoderm which will become the digestive and respiratory systems. The mesoderm which will become the muscle and skeletal systems. this domian is physical -
embryonic stage
the embryonic stage is where the fetus is becoming a baby and growing at a rapid speed. this goes until the fourth week until the eight week. -
body system
This is where the fetus divides into three layers each will become an important body system. About 22 days after the conception the neural tube forms. this tube will later form into the central nervous system, the spinal cord and the brain. this domain is physical -
physical development
This is where the physical appearance of the fetus begins to form. the head begins to form quickly followed by the eyes, nose, ears, and mouth.The cardiovascular system is where the activity begins as the blood vessel that will become the heart start to pulse.buds that will form the arms and legs will appear. this domain is physical -
fetal stage
by the start of the fetal stage all the basic organs and parts except the sex organs will have been formed at this point. this is just about the body continuing to develope and get stonger. this period goes until the ninth week till birth. -
the fetus
the early body systems and structures continue to develope. the sex organs being to appear. the fetus grows in length and weight, the magority of the physical growth occures in the later stages of the pregnancy, this domain is physical -
fetal growth
this stage is marked by amazing change and growth. during the third month gestation, the sex organs began to differentaite and by the end of the month all the parts of the body will be formed, at this point the baby weighs about three ounces, this domain is physical.. -
heartbeat
During this time the heartbeat grows stronger and other body systems become further developed. The fingernails, hair, eyelashes and toenails form and most noticeably. this domain is physical -
size
By now the fetus has increased dramatically in size, about six times in size. The brain and central nervous system also become responsive during this time. this domain is physical -
mature
The brain starts to mature much faster with the activity that greatly resembles a sleeping newborn. The fetus continues to develop, put on weight, and prepare for life outside of the womb. The lungs begin to expand and contract, preparing the muscles for breathing. this domain is physical -
newborn baby
all the stages of prenatal development are done and now it is time to welcome a baby to this world. even though this pregnancy went good were lucky no problems went on in these stages. this domain is physical and social
