Question

question 6

which of the following happens when an object is placed in an infants hand?

moro reflex
palmar grasp
babinski reflex
pincer grasp

Explanation:

Identify the stimulus and response

The question asks what happens when an object is placed in an infant's hand. This describes a tactile stimulus to the palm of the hand, which triggers an involuntary, automatic curling of the fingers to grip the object.

Analyze the options

• Moro reflex: This is the startle reflex in response to a sudden loss of support or a loud noise, where the infant flings out their arms and then pulls them back in.
• Palmar grasp: This is an involuntary reflex where placing an object or finger in an infant's palm causes them to automatically grasp it.
• Babinski reflex: This occurs when the sole of the foot is firmly stroked, causing the big toe to bend back toward the top of the foot and the other toes to fan out.
• Pincer grasp: This is a voluntary motor milestone (typically developing around 9–12 months) where the infant uses the index finger and thumb to pick up small objects, rather than an automatic reflex triggered by placing an object in their hand.

Determine the correct match

The automatic reflex triggered by placing an object in an infant's hand is the Palmar grasp (also known as the palmar grasp reflex).

Answer:

• (A) Moro reflex
• (B) Palmar grasp (Correct answer)
• (C) Babinski reflex
• (D) Pincer grasp
