Document Summary
Postural reflexes important for: providing automatic movement that is practice for future voluntary movements. Elicited by applying pressure to infant"s palm and they would grasp it. Elicited by touching lips and infant would produce an oral sucking action. Important for survival because it enables baby to ingest by involuntary means, taking nutrients essential for survival. Elicited by stroking check, baby turns head towards that direction. Elicited by fake dropping baby and baby would brace for fall by extending arms and legs.
