Question

Quizplus · Accepted Answer

The described response of arching the back, flailing the arms, and then bringing them together in an embrace is characteristic of the Moro reflex, also known as the startle reflex. This reflex is triggered by sudden changes in movement or noise, such as the crash of thunder. The Babkin reflex involves opening and closing the mouth in response to pressure on the palms, the rooting reflex involves turning the head towards touch on the cheek, and the Babinski reflex involves the fanning out of toes when the sole of the foot is stroked. None of these reflexes are the most appropriate choice for this scenario.
