Question

Quizplus · Accepted Answer

The startle response of arching the back, flinging out the arms and legs, and then relaxing is called the Moro reflex. It usually occurs in response to a sudden noise or movement, and it is present in newborns until around 3-4 months of age. The sucking reflex (A) is when a newborn instinctively starts sucking when a nipple or object is placed in their mouth. The rooting reflex (B) is when a newborn turns their head and opens their mouth in response to a touch on their cheek or mouth area, signaling they are ready to feed. The Babinski reflex (D) is when the sole of a newborn's foot is stroked, and their toes fan out and curl up.
