Neonatal and Infant Dermatology 3rd edition PDF free download – The skin simultaneously contacts a changing environment and provides closure for the body. It is a cellular and molecular interface, which plays a critical functional role in neurobehavior and perception.1 The skin is embryologically continuous with the nervous system via involution and with the amnion via simple lateral extension. Thus, with regard to the fetoplacental unit, the skin is an ‘internal’ organ marking the boundary between the developing nervous system and the fetal membranes surrounding the liquor amnii.
Few organs carry such capacity to convey and evoke emotion. The experiments of Hooker and Humphrey, for example, provide unequivocal video evidence that localized tactile stimulation of the skin of the human embryo as early as 8–9 weeks’ gestation will evoke a reflex response. Thus, even early in development, the skin cannot be considered apart from the developing central nervous system and other fetal organs, nor, as will be demonstrated in this chapter, from the changing dynamics of its aqueous environment and maternal enclosure.
