Importance of neonatal reflexes

HEY!!!!!
THIS IS THE ANSWER YOU WERE LOOKING FOR ........
INFANT / NEONATAL REFLEXES :
A reflex is a muscle reaction that happens automatically in response to stimulation. Certain sensations or movements produce specific muscle responses.
Considerations
The presence and strength of a reflex is an important sign of nervous system development and function.
Many infant reflexes disappear as the child grows older, although some remain through adulthood. A reflex that is still present after the age when it would normally disappear can be a sign of brain or nervous system damage.
Infant reflexes are responses that are normal in infants, but abnormal in other age groups. These include:
Moro reflex
Sucking reflex (sucks when area around mouth is touched)
Startle reflex (pulling arms and legs in after hearing loud noise)
Step reflex (stepping motions when sole of foot touches hard surface)
Other infant reflexes include:
TONIC NECK REFLEX
This reflex occurs when the head of a child who is relaxed and lying face up is moved to the side. The arm on the side where the head is facing reaches away from the body with the hand partly open. The arm on the side away from the face is flexed and the fist is clenched tightly. Turning the baby's face in the other direction reverses the position. The tonic neck position is often described as the fencer's position because it looks like a fencer's stance.
TRUNCAL INCURVATION OR GALANT REFLEX
This reflex occurs when the side of the infant's spine is stroked or tapped while the infant lies on the stomach. The infant will twitch their hips toward the touch in a dancing movement.
GRASP REFLEX
This reflex occurs if you place a finger on the infant's open palm. The hand will close around the finger. Trying to remove the finger causes the grip to tighten. Newborn infants have strong grasps and can almost be lifted up if both hands are grasping your fingers.
ROOTING REFLEX
This reflex occurs when the baby's cheek is stroked. The infant will turn toward the side that was stroked and begin to make sucking motions.
PARACHUTE REFLEX
This reflex occurs in slightly older infants when the child is held upright and the baby's body is rotated quickly to face forward (as in falling). The baby will extend his arms forward as if to break a fall, even though this reflex appears long before the baby walks.
Examples of reflexes that last into adulthood are:
Blinking reflex: blinking the eyes when they are touched or when a sudden bright light appears
Cough reflex: coughing when the airway is stimulated
Gag reflex: gagging when the throat or back of the mouth is stimulated
Sneeze reflex: sneezing when the nasal passages are irritated
Yawn reflex: yawning when the body needs more oxygen
