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.

spinal cordautotomicspinal cord in the central nervous system controls reflex arc and reflex action.
Reflex. Reflexes ensure that a organism responds to an event in a way most likely to result in survival. For example, when touching a hot surface, most people will immediately jerk their hand away.
Jump reflection is a a reflex action that takes place under the control of spinal cordand not the involvement of CNS. Eg. When we stamp on a nail or on an hot plate we immediately move the leg because of reflex action.

The difference between reflex and voluntary action is that a reflex occurs naturally in response to some sort of stimulus and voluntary action is something that is consciously carried out. An example of a reflex action is gagging and an example of voluntary action is flinching when someone is going to hit you.

Conscious action is a voluntary action that is initiated and controlled by our conscious thoughts and decisions, while reflex action is an involuntary and automatic response to a stimulus that involves a specific neural pathway without requiring conscious thought. Conscious actions are typically intentional and involve higher levels of cognitive processing, whereas reflex actions are rapid and predictable responses designed to protect the body from harm.
A reflex action is an "automatic" and sometimes involuntary action caused by the presence of a stimulus.The action requires no conscious thought and will happen naturally.An example is someone waving ther hand very close to your face, you will naturally blink.This is a reflex action.
The value of a reflex action is to survive. For example, if we place our hands on a hot oven. Our reflex would be to take our hand off and register the pain. OR A perfect example would be the rooting reflex. Which helps a breastfed infant find the mother's nipple. Babies display it only when hungry and touched by another person, not when they touch themselves.
The reflex arc is the nerve pathway that the signal follows. For example, the knee jerk reflex arc has a stimulus going to an interneuron in the spine and a motor neuron completes the arc by causing the knee to jerk. A reflex is just the action itself.

knee jerk aka patellar reflex is an example of a stretch reflex
Conscious action is a voluntary action that is controlled by the brain and involves awareness and decision-making, such as raising your hand. Reflex action is an involuntary action that is controlled by the spinal cord and occurs without conscious thought, such as quickly pulling your hand away from a hot surface.
Reflex action is the instant reaction of our body while hormonial action takes more time to react
