Blink reflex is the rapid eye closure exhibited by newborns upon coming of objects near it Similar with adults, this reflex serves a protective function against hurting the eye It can be elicited by shining a strong light (eg flashlight, otoscope light, etc) on the eyes Blink reflex can also be elicited by a sudden movement of an object towards the eye.

Cranial nerves (CN) II and III can be tested by the pupillary reflex, which appears consistently at 32 to 35 weeks gestation A 28week infant will blink to light shone into the eyes, testing CN II and VII Beginning at 34 weeks of gestation, an infant will be able to fix and follow on an object, thus testing CN II, III, IV, and VI. The blink reflex is a reflex which is designed to naturally protect the eyes Most animals with eyes have some form of this reflex, and the reflex is present from the time that an animal first opens its eyes Abnormalities in this reflex can indicate that there is a neurological problem and may increase the risk of incurring eye damage because. Auditory orienting reflex A sudden loud and unpleasant noise May produce the blink reflex Infant may remain still and show increased alertness Quieter sounds usually cause reflex eye and head turning to theside of the sound, as if to locate it Seen first at about 4 months of age Thereafter, head turning towards sound stimuli occurs and.

The blink reflex, the electrical version of the corneal reflex, represents a polysynaptic reflex Electrical stimulation of the supraorbital branch of the trigeminal nerve on one side results in a reflexive activation of the facial nucleus, causing contraction of the orbicularis oculi muscle bilaterally.

This is due to the lack of maturity of the infants neurological system This is a normal reflex and may disappear as early as 6 months and as late as 2 years Functional significance A Babinski reflex in an older child or adult is atypical and is a sign of a problem in the brain or spinal cord. •Stimulated when an object is placed into the baby’s palm •A normally developing neonate responds by grasping the object •This reflex emerges 11 wks in utero, and is inhibited 23 months after birth •A persistent palmar grasp reflex may cause issues such as swallowing problems and delayed speech (Grupen). These reflexes are somewhat automatic and not in his control To give an example if one strokes a newborn's hand or foot on either the top or back then whole arm or leg withdraws slightly and then the feet or hands flex and turn They turn as a mechanism to grasp your finger.

Primitive reflexes are reflex actions originating in the central nervous system that are exhibited by normal infants, but not neurologically intact adults, in response to particular stimuliThese reflexes are suppressed by the development of the frontal lobes as a child transitions normally into child development These primitive reflexes are also called infantile, infant or newborn reflexes.
