Reflexes are is an involuntary [ say :in-val-lun-ter-tee] or automatic, action that your body does in response to something - without you even thinking about it.
Reflexes are simply you body automatically doing something without the train of thought put into the exercise.
A reflex action is an automatic instinctive unlearned reaction to a stimulus. It does not involve cognitive processes.
The typical example would be that if you were to place your hand onto something hot, you body would withdraw you hand automatically before you realized what you had done (it would still hurt but you hand would be off the heat)
A reflex action is an instantaneous movement in response to a stimulus.
its a red glow that's reflected from Fundus of eyes, when light is cast on retina, like in retinoscopy
Reflex tests are simple physical tests of nervous system function.
A reflex action, differently known as a reflex, is an involuntary and nearly instantaneous movement in response to a stimulus
the eye ears all play apart of the equilibrium system which helps us keep our balance.
reacting when someone flashes his or her hand to your face that includes blinking-------------------------------------------------------A reflex action is a sudden reaction to a stimuli (a change in the environment) & often acts to protect you.Some are controlled by the brain (cranial reflexes) such as when you blink as dust lands in your eye, or your pupil gets smaller as light is shone in your eye.Some reflexes are controlled by the spinal cord (spinal reflexes) such as when you touch a hot object or stand on a pin.Some reflexes can have learnt responses so they are calledconditioned reflexes. These reflexes occur without you even thinking about them e.g. walking & producing saliva when you smell food.
Normal reflexes
The Human Reflex Physiology Review Sheet states that "Conversely, other reflexes require the involvement of the brain, since many different inputs must be evaluated before the appropriate reflex is determined. Superficial cord reflexes and pupillary responses to light are in this category" (p. 342).
Reflexes aren't actually controlled by the brain. When you blink in surprise or kick at the doctor's office, sensory nerves brought the signal to your spinal cord (encased in your vertebrae), which sent the message to act back. Reflexes are spinal.
The structure responsible for conducting impulses between brain parts and controlling some eye reflexes is the midbrain. It plays a crucial role in coordinating basic movements and visual and auditory processing.
Bcz of reflexes sometimes nerves of our eyes exprience reflexes which leads to fast process of our body including our eyes process is directly done by our brain.
The area of the brainstem concerned with eye tracking reflexes involved in reading is the superior colliculus. It plays a crucial role in controlling rapid eye movements, called saccades, which are important for shifting attention between words or lines while reading. Damage to the superior colliculus can lead to difficulties in reading fluency and eye movement coordination.
Reflexes are automatic, involuntary responses or impulses. Most reflexes do not involve the brain, however, more complex reflexes have to involve the brain in order to process the reflexes. An example of this would be blinking the eye. This is a complex reflex and it must involve the brain. Also, you must take in the place the reason why reflexes do not involve the brain: because it could cause serious damage to the body. Complex reflexes will not cause serious damage if it uses to brain to produce the impulse.

"Reflexes 2" or "reflexes +2" indicates normal reflexes.

Normal reflexes
The ciliospinal reflex and the pupillary light reflex are classified as autonomic reflexes.
Babies are born with reflexes. These reflexes, such as rooting and sucking, make it so the baby can survive.
