Neural Exam - Newborn reflexes - Moro
(startle reflex) Clinical term describing a primitive reflex, an involuntary response (reflex) that is present at birth and that normally disappears after 3 or 4 months. The reflex has 4 parts: startle; abduction of the upper limbs (spreading out arms); adduction of the upper limbs (unspreading the arms); crying (usually, but may be absent). Preterm birth infants (28 to 33 weeks) have an incomplete form of this reflex and postnatal persistence (beyond 4 or 5 months) occurs in infants with severe neurological defects.
