Moro’s Reflex is not present from which milestone age of development?
**Core Concept:** Moro's Reflex is a primitive startle response seen in infants which involves sudden extension of the arms and legs upon initial awakening from sleep or when startled. It is an important milestone in the development of reflexes.
**Why the Correct Answer is Right:** Moro's Reflex is one of the earliest reflexes that develop in the fetus and is observed in infants during the first few months of life. It is a critical developmental milestone as it helps the infant to quickly orient towards their environment, ensuring their survival and adaptation.
**Why Each Wrong Option is Incorrect:**
A. Moro's Reflex is present in infants up to around 6 months of age, not from 18 months as suggested by Option A.
B. Option B suggests that the reflex is lost during the first few months, which is incorrect as it persists for a longer period.
C. Like Option A, Option C also refers to the incorrect age range for the disappearance of Moro's Reflex.
D. Moro's Reflex is an important developmental milestone and should not be considered absent from any specific age.
**Clinical Pearl / High-Yield Fact:** Moro's Reflex helps infants adapt to their environment and is an essential part of their neurological development. It gradually fades away as other reflexes develop, ultimately giving way to voluntary motor skills. Understanding the timing of this reflex is crucial for assessing an infant's neurological development and identifying potential issues.
