Physiologic differences between infants, children and adults. I. Central Nervous System. Myelination of nerve fibers incomplete in newborn, muscle tone and reflexes are different (rooting/suckling reflex etc.), cerebral cortex less developed. Pain threshold of young children is lower than that of older children or adults because of more nerve endings/cm2 and immature inhibitory pathways. Infant skull much less rigid than adult; can estimate ICP by palpation of fontanelle. Autoregulation of CBF impaired in the sick newborn.
