Detailed Solution
Download Solution PDFNewborns exhibit several primitive reflexes, which are automatic movements in response to specific stimuli.
Key Points
- If a baby's sole is stroked, and she first spreads her toes and then curls them, she is exhibiting the Babinski reflex. This reflex is a normal response in infants up to 12-24 months of age and indicates proper neurological function.
- When the bottom of the foot is stimulated, the big toe moves upward (dorsiflexion), while the other toes fan out.
- In older children and adults, the presence of this reflex may indicate neurological issues.
Thus, the correct answer is Babinski reflex.
Hint
- Rooting reflex: When a baby's cheek is touched, they turn their head in that direction and open their mouth, preparing for feeding.
- Moro reflex: Also known as the startle reflex, it occurs when a baby suddenly spreads and then brings their arms back in response to a loud sound or sudden movement.
- Grasp reflex: When an object is placed in a baby’s palm, they instinctively close their fingers around it.
