Finally, in adults, the head represents approximately 12% of the body length. The cephalocaudal trend is also the trend of infants learning to use their upper limbs before their lower limbs. The proximodistal trend, on the other hand, is the prenatal growth from 5 months to birth when the fetus grows from the inside of the body outwards.
There is a genetic cephalocaudal (head-to-foot) trend in both prenatal and postnatal development. [ 2 ] As a baby grows, they learn to sit up, stand, walk, and run; these capacities develop in a specific order with the growth of the nervous system, even though the rate of development may vary from child to child.
Psychological sex differences are thought by some to reflect the interaction of genes, hormones, and social learning on brain development throughout the lifespan. A 2021 meta-synthesis led by Lise Eliot found that sex accounted for 1% of the brain's structure or laterality, finding large group-level differences only in total brain volume. [ 1 ]
Sex assignment (also known as gender assignment [1] [2]) is the discernment of an infant's sex, typically made at birth based on an examination of the baby's external genitalia by a healthcare provider such as a midwife, nurse, or physician. [3] In the vast majority of cases (99.95%), sex is assigned unambiguously at birth.
Like physical growth, motor development shows predictable patterns of cephalocaudal (head to foot) and proximodistal (torso to extremities) development, with movements at the head and in the more central areas coming under control before those of the lower part of the body or the hands and feet.
