Development of Normal Fetal Movements

Development of Normal Fetal Movements provides a detailed reasoned map of fetal behavior by describing features and evolution from 10 to 25 weeks gestation. Each behavioral event is described, measured and presented as it occurs in its natural sequence, providing a 'real-time' picture of fetal behavior.

This work sees the light for various reasons. There is a general lack of detailed information about the earliest stages of human motor development. The reasons for this are explained more fully in the Introduction; here we may simply state that, apart from their intrinsic interest, earlier phenomena are fundamental to the comprehension of later phenomena rooted in them, whether pathological or normal. This is especially so in the rapidly - veloping young organism. At birth the neonate is catapulted into a profoundly different physical and social envir- ment requiring extremely diverse functioning: suffice it to mention aerial respiration, no longer being fed through the placenta and the cord, and the full impact of gravity on neonatal movements. The neonate generally adapts smoothly to the transition, as it has been equipped to do so during the 9 months of pregnancy. However, the study of the early stages of fetal motor development should not be exclusively directed towards the und- standing of functioning in the neonate.

Klappentext
This work aims to provide a detailed reasoned map of fetal behavior by describing its features and evolution from 10 to 25 weeks gestation. Each behavioral event is described, measured in seconds and presented as it occurs in its natural sequence, thus providing a 'real-time' picture of fetal behavior. Links between events become clear, and events are connected to the changing anatomy and physiology of the nervous system and of the fetal body in general. Transient behaviour with its underlying structures and possible functions is carefully distinguished from anticipatory functions heralding post-natal life. Furthermore, phenomena of physiologic significance during prenatal life, but which can acquire pathological connotations for the premature infant having to meet the different requirements of the post-natal environment, are also outlined. Finally, various prenatal 'myths' are discussed, in order to give scientific information on issues;that are particularly relevant, given the heatedpro-life versus pro-choice debate.
