[Kinesiologic and neurologic basis of asymmetry]

Ciclical motory trajectories with crossed scheme, tend to develop according to helicoidal schemes, and their morphologies are determined by such configurations which constitute a functional necessity of the organism. Anatomical structures, even if they have hereditary matrices which are created by the philogenetic adjustment mould themselves ontogenetically on the ground of functional experiences. They adapt themselves to operative situations which are peculiar to each subject. The asymmetrical growths fit in such a context.
