Which of the following reflexes are present at birth?
**Core Concept**
The question tests the knowledge of neonatal reflexes, which are essential for assessing the neurological development and maturity of newborns. These reflexes are involuntary movements that are present at birth and are crucial for the baby's ability to survive and adapt to the environment.
**Why the Correct Answer is Right**
The correct answer is the **Grasping Reflex**, also known as the palmar grasp reflex. This reflex is present at birth and allows the baby to grasp an object placed in the palm of the hand. The grasping reflex is mediated by the spinal cord and is a result of the contraction of muscles in the hand and forearm. When an object is placed in the palm, the sensory receptors in the skin send signals to the spinal cord, which then triggers the muscles to contract and grasp the object.
**Why Each Wrong Option is Incorrect**
* **Option A:** The **Rooting Reflex** is present at birth and allows the baby to turn the head towards a nipple when the cheek or lips are stroked. However, it is not the correct answer because the question specifically asks for reflexes present at birth, and the rooting reflex is primarily involved in feeding.
* **Option B:** The **Tonic Labyrinthine Reflex (TLR)** is not present at birth and typically appears around 6-12 months of age. It is a reflex that helps the baby maintain balance and posture.
* **Option D:** The **Plantar Reflex**, also known as the Babinski reflex, is present at birth and is elicited by stroking the sole of the foot. However, it is not the correct answer because the question specifically asks for reflexes that are present at birth, and the plantar reflex is primarily involved in assessing neurological development.
**Clinical Pearl / High-Yield Fact**
It's essential to remember that reflexes can be used as a tool to assess the neurological development and maturity of newborns. The presence or absence of certain reflexes can indicate potential neurological issues or developmental delays.
**Correct Answer: C. Grasping Reflex**
