Conception (0 weeks)
Fertilization of the egg by the sperm occurs, forming a single cell called a zygote. -
Period: to
Conception Factors
Factors for Maximum Development: Adequate nutrition, including folic acid, which supports neural tube development. -
Period: to
First Trimester
Weeks 1-12 of pregnancy
-Baby conceived
-Pregnancy test positive
-Heartbeat detectable by ultrasound -
Germinal Stage (0-2 weeks)
Rapid cell division takes place, and the zygote develops into a blastocyst. Implantation into the uterine wall occurs around the end of this stage.
- Fertilization occurs, forming a zygote.
- Rapid cell division takes place.
- The zygote implants itself into the uterine wall. -
Period: to
Gereminal Factors
Factors for maximum development: A healthy and supportive environment for the embryo. -
Period: to
Brain Development And Factors
- Begins during the embryonic stage and continues throughout pregnancy.
- Formation of neurons, synapses, and the central nervous system.
- Factors for maximum development: Adequate nutrition, including omega-3 fatty acids, folic acid, and iron, as well as a stimulating environment with positive interactions and experiences.
-
Embryonic Stage (3-8 weeks)
Major organ systems begin to develop.
- The heart starts beating.
- Limbs, facial features, and internal organs start forming.
- The neural tube develops, which eventually becomes the brain and spinal cord. -
Period: to
Embryotic Factors
Factors for maximum development: Proper nutrition, adequate prenatal care, and avoidance of harmful substances like alcohol and drugs. -
Period: to
Fetal Factors
Factors for maximum development: Good maternal health, regular prenatal check-ups, a balanced diet, stimulation through sound and touch, and a safe and stress-free environment. -
Fetal Stage (9 weeks to birth)
Rapid growth and development continue. The fetus develops fully formed organs and systems. Brain development accelerates, and the fetus begins to exhibit reflexes and movements.
- Rapid growth and refinement of body structures.
- Brain development continues throughout this stage.
- By the end of the first trimester, all major organs are formed.
- The fetus begins to move, hear, and respond to external stimuli. -
Period: to
Second Trimester
Weeks 13-27 of pregnancy
-Miscarriage risk decreases
-Baby begins making noticeable
movements, can hear sounds,
and gender can be found out.
-Premature baby may survive -
Period: to
Third Trimester
Weeks 28-40 of pregnancy
-Baby can breathe -
Birth
Delivery: Baby is born, usually between 37-42 weeks of gestation
