Human Growth Pattern
non linear
Year 0-2
infant phase
11-Feb
childhood phase
18-Nov
adolescent phase
18-32
adult phase
32+
aging phase
Growth begins at
conception
Carnegie Stages of Human Development
Based on both internal and external development and not on age or size. By comparing common stages between organisms you can compare the development time between species.
deviations of growth patterns
major developmental issues
canalized
growth remains on a tightly programmed course
Weeks 3-8 (embryonic period)
cephalic-caudal
SRY gene
sex determining region of the Y chromosome
8/9 weeks (fetal period)
major growth in size
premature birth
more than 3 weeks early
premature survival unlikely
<23 weeks
Early gestation stress
cardiovascular disease, general poor health
mid gestation stress
kidney disease associated with diabetes, lung disease
late gestation stress
insulin resistance (diabetes)
Infancy
0-2
Childhood
2-puberty
Adolecence
begins with puberty
Sexual dimorphism in growth
male and female growth rates,
by age 6
95% of the brain is formed
colostrum
first form of breast milk
Adipose Tissue
15th week gestation
white AT
result of storing excess calories
Brown AT
metabolically active
Adiposity
being severely overweight
thrifty phenotype hypothesis
In utero stress impacts the way DNA is read
