What reflex is demonstrated when an infant appears to stand when held upright?

• A. Positive reflex
• B. Moro reflex
• C. Stepping reflex
• D. Palmar grasp

Answer: (A)

The reflex demonstrated when an infant appears to stand when held upright is known as the stepping reflex. This is an innate response observed in newborns, typically when the infant's feet come into contact with a flat surface. As the baby is held in an upright position, they may begin to make rhythmic stepping motions, which mimic the action of walking. This reflex usually appears within the first few weeks of life and may last until the infant is around 2 months old. It is a sign of healthy neuromuscular development and indicates that the baby's brain and muscles are engaged in basic motor functions. The positive reflex option does not accurately describe any specific reflex associated with infant behavior. The Moro reflex, which is distinct from the stepping reflex, involves an involuntary response where an infant throws their arms out and then pulls them back in when startled. Finally, the palmar grasp reflex involves the infant's ability to tightly grasp an object placed in their palm but does not relate to standing or walking movements.
