primitive reflex
Automatic movement responses present at birth that typically integrate as the nervous system matures.
Full Definition
Primitive reflexes are stereotyped movement patterns controlled by the central nervous system that appear in utero and early infancy. These reflexes, including the Moro, rooting, and asymmetrical tonic neck reflexes, serve protective and survival functions in newborns. Normal development involves the integration or suppression of these reflexes by specific ages to allow for voluntary motor control. Persistence of primitive reflexes beyond expected timeframes may indicate neurological dysfunction or developmental delays.
