When something like a hot object touches your hand, your receptors send impulses down the sensory neurone which then takes the impulses to the relay neurone (co-ordinator) which then sends the impulses to the motor neurone which goes in the opposite direction to an effector organ. This then reflexes your hand away from the hot object.
Reflex actions are involuntary and immediate reactions to a stimulus.
Two examples are:
-------------------------------------------
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.
One example of a reflex is when your leg jerks after a doctor hits it with a hammer.

hit your knee cap, your lower leg swings up with no effort.
An example of reflex action is pulling your hand when the doctor injects it. This is usually a response from the body which happen automatically.
blinking,coughing,sneezing,with trawing of hands when you touch a hot object,burping
blinking
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.

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.
Blinking
No it is not a reflex action
brain and the spinal cord will reaction
Reflex is when something in your body does natuarally (can't stop) and conscious action is when you respond and act towards it. For example: if a bee stung you, you quickly move away
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.

Reflex action
knee jerk aka patellar reflex is an example of a stretch reflex
A reflex action is an action by which your body does subconsciously or naturally whereas a conscious action is an action that you intentionally respond and act towards.
Reflex action is the instant reaction of our body while hormonial action takes more time to react
