44
Germinal: Age
Fertilisation-Implantation
45
Embryonic: Age
3-8 weeks
46
Foetal: Age
9-38
47
Week 1: Overview
- Fertilisation occurs when a sperm cell combines with an egg cell to form a zygote - Thirty hours after fertilisation, the process of cell division begins and will continue for life - After three days, the zygote consists of 16 cells - The zygote travels down the fallopian tube and into the uterus
48
Week 2: Overview
- Around a week after fertilisation, the ball of cells (blastocyst) begins to implant into the endometrium. The implantation process takes about a week to complete - The formation of the placenta begins
49
Week 3: Overview
- Implantation is complete, the developing baby is referred to as an embryo - Cells continue to divide rapidly and start taking on specialised roles as the organs begin to develop
50
Week 4: Overview
- The tissues that will become the brain and spine (the neural tube) start to develop - Around 3 millimetres in length, the embryo secretes hormones to maintain the endometrium and to prevent the mother from having a menstrual period
51
Week 5: Overview
- Buds appear on each side of the embryo that will become the limbs, the heart begins to beat - Brain cells are being generated at a rate of 100 per minute
52
Week 6: Overview
- The spinal cord looks like a tail and the head is large in relation to the rest of the body - The embryo is approximately 1.3 centimetres long
53
Week 7: Overview
- Blood cells are being made in the liver - Facial features such as the eyes and mouth are forming - Tiny muscles have formed, which allow the embryo to move
54
Week 8: Overview
- The embryo is around 2.5 centimetres in length - Fingers and toes are starting to form - The brain is now active
55
Week 9-38: Overview
- The developing baby is now known as a foetus - All the body’s organs are formed but not all are functioning at this point - The foetus is around 7 centimetres in length in week 11 - Teeth are beginning to form in the gums - Eyelids are fused over the eye
56
Week 14-18: Overview
- The foetus is around 14 centimetres in length in week 14 - The tongue develops taste buds - Ears are fully functioning and the foetus can hear muffled sounds from the outside world - The sex of the foetus can be distinguished via an ultrasound
57
Week 19-23: Overview
- The foetus is around 33 centimetres in length in week 22 - The foetus will swallow regularly but takes in only amniotic fluid - The eyelids separate into upper and lower lids and the foetus can open and shut its eyes
58
Week 24-28: Overview
- The foetus is around 37 centimetres long and weighs approximately 1 kilogram - The fingers and toes grow nails - The foetus’s body has grown and it is now more in proportion with the size of the head but will take until childhood to completely catch up - In preparation for breathing, production of surfactant begins
59
Week 29-33: Overview
* The foetus spends most of its time asleep. * Eyebrows and eyelashes grow * Fat is laid down under the skin to assist with adjusting to life outside the uterus * The foetus moves in a strong and coordinated way
60
Week 34-38: Overview
- The foetus assumes the ‘head down' position in preparation for birth - The lungs develop at a rapid rate during this time - The foetus is around 50 centimetres in length
61
Risk Factors: Definition
increases the likelihood of developing disease of injury
62
Risk Factors: Example
- poverty - alcohol consumption - drug use - tobacco use - maternal age - stress - undernutrition - low oxygen levels at birth, can’t maintain body temp, infection, SIDS
63
Protective Factors: Definition
enhances the likelihood of a positive health and wellbeing outcome and lessen the likelihood of negative health and well-being outcomes from exposure to risk
64
Protective Factors: Example
- parenting information - appropriate weight gain - antenatal care - monitor and promote the mother's health - emotional support - nutritious diet - immunisation
65
Maternal Diet: Avoid
soft-serve ice cream, unpasteurised foods, pre-cooked or prepared cold foods, raw seafood
66
Folate (folic acid): definition
B-group vitamin required for the formation of red blood cells, which transport oxygen around the body
67
Folate (folic acid): Deprivations
- Neural tube defects: failure of the neural tube (which develops into the central nervous system) to close during the development of the embryo, resulting in conditions such as spina bifida - Spina Bifida; walking difficulties, sexual dysfunction, urinary/faecal incontinence, deformations of the spine (scoliosis)
68
Iodine: Definition
make thyroid hormones thyroxine and triiodothyronine
69
Iodine: Deprivations
- Reduced brain cell branching: fewer connections and lower IQ
70
Iron: Definition
component of hemoglobin (transfers oxygen from the lungs to tissues)
71
Smoking: Causes
low birthweight, miscarriage, ectopic pregnancy, prematurity, birth defects, lung function abnormalities and respiratory conditions, perinatal mortality
72
Alcohol: Causes
- Foetal Alcohol Spectrum: seen in the facial features of affected children - H&W: increased risk of premature birth, undernourishment, reduction in amount of oxygen, stillbirth - PD: low birthweight, smaller head circumference, small eyes, flattened face, heart defects
73

77

78
Developmental Milestones: 2 Months
