parachute reflex

(redirected from Anterior Propping Reaction)

star·tle re·flex

a primitive reflex response observed in the normal newborn but typically suppressed by 3-4 months of age. Any sudden stimulus (for example, a loud noise, a blow to the supporting surface, or being dropped 5-10 cm through space) causes flexion of the hip and knee joints with fanning of the fingers followed by fist clenching and extension of the upper limbs followed by flexion. Synonym(s): Moro reflex, parachute reflex, startle reaction
