Final answer:
Babinski, grasping, and sucking signs are examples of primitive reflexes in newborn babies. These reflexes are involuntary movements or responses that help babies survive in their early months.
Step-by-step explanation:
Babinski, grasping, and sucking signs are examples of primitive reflexes. These reflexes are involuntary movements or responses that are present in newborn babies. The Babinski sign is elicited by stroking the sole of the foot, causing the toes to extend and fan out, which is a normal response in infants. The grasping reflex is when a baby instinctively grasps onto an object placed in their palm. The sucking reflex is the automatic, unlearned, sucking motions that infants do with their mouths when anything touches their cheek.
