Explanation
The Moro reflex, or startle reflex, is an involuntary response to a sudden loss of support or a loud noise that involves spreading and curling the arms and legs.
The Moro reflex involves three distinct components: spreading out the arms (abduction), pulling the arms in (adduction), and crying (usually). The baby may also extend and flex their legs.
The Moro reflex can be used to assess the integrity of the baby’s nervous system, as it reflects the development and function of the brain stem. Absence, asymmetry, or persistence of the Moro reflex may indicate neurological problems.
