Which of the following correctly describes the Moro reflex in newborns?

BOn a loud noise the baby throws arms outward, arches the back, then brings the arms together
CWhen the palm is pressed by a finger the baby's fingers close around it
DWhen the bottom of the foot is stroked the toes fan out and then curl
Answer & Solution
Correct answer: B. On a loud noise the baby throws arms outward, arches the back, then brings the arms together
1. Table 3.1 lists four reflexes of the newborn with descriptions and timelines.
2. The Moro reflex row reads: on a loud noise the baby throws arms outward.
3. The baby simultaneously arches the back and brings the arms together as if grasping.
4. Distractor 2 describes the Rooting reflex on cheek touch.
5. Distractor 3 describes the Grasp reflex when the palm is pressed.
6. Distractor 4 describes the Babinski reflex on stroking the foot.
7. Hence the loud-noise, outward-arms reflex is the Moro reflex.
