Baby Ian and His Reflexes

What is Baby Ian demonstrating when he is held horizontally on his back and makes an "embracing" motion?

A. Startle reaction
B. Moro Reflex
C. Routine activities
D. Unplanned movements

Answer:

B. Moro Reflex

When Baby Ian is held horizontally on his back and demonstrates an "embracing" motion by arching his back, extending his legs, throwing his arms outward, and then bringing them in toward his body, he is actually showing the Moro Reflex. This reflex is commonly known as a startle reaction.

The Moro reflex is typical in newborns and is often triggered by a sudden loud noise or movement that startles the baby. When this happens, the infant will instinctively stretch out their arms and legs, followed by a cry, and then bring their limbs back in towards their body.

It is important to note that reflexes like the Moro Reflex are involuntary and are used by medical professionals to assess the proper functioning of the brain and nervous system in infants. While some movements are part of routine activities, others, like the Moro Reflex, are reactive responses to external stimuli.
