Explanation: MORO REFLEX is also known as embrace reflex or stale reflex. It is a reflex seen in infants in response to stimuli, e.g. that produced by suddenly striking the surface on which the infant rests. To elicit this reflex the head is momentarily allowed to fall back and then is re suppoed by the examiner's hand. The child symmetrically abducts and extends the arms, flexes the thumbs. This movement is followed by flexion and adduction of upper extremities. Persistence of Moro's reflex beyond 12 weeks indicates neurological damage.
