Question

Quizplus · Accepted Answer

Anna is demonstrating the Moro reflex, also known as the startle reflex. This reflex is triggered when a baby is startled by a sudden movement or noise, causing them to throw their arms out and then bring them back together as if hugging themselves. It is a normal reflex seen in newborns and typically disappears by around 3-6 months of age. The other reflexes listed (Babinski, palmer grasp, rooting) are not associated with the scenario described.
