Question

Quizplus · Accepted Answer

The described response of arched back, flailed arms, and then bringing them together in an embrace is characteristic of the Moro reflex, which is triggered by sudden changes in sensory input, such as a loud noise. The Babkin reflex is elicited by stroking the palms of the hands, the rooting reflex involves turning the head and opening the mouth in response to 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 match the described response.
