One example of a reflex is when your leg jerks after a doctor hits it with a hammer.
-------------------------------------------
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 called conditioned reflexes. These reflexes occur without you even thinking about them e.g. walking & producing saliva when you smell food.
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.

brain and the spinal cord will reaction
No it is not a reflex action
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.
Conscious thought might intervene to modify a reflex action when the situation requires a more complex or nuanced response than the reflex can provide. For example, if a reflex action is not appropriate for the current context or if a quick decision needs to be made based on multiple factors, conscious thought can override the reflex to ensure a more suitable response.
knee jerk aka patellar reflex is an example of a stretch reflex
This is an example of a reflex action, which is an involuntary and rapid response to a stimulus in order to protect the body from harm. In this case, the child's hand was quickly removed from the hot stove to prevent further injury.
Reflex action is the instant reaction of our body while hormonial action takes more time to react
The verb "trow" means to think or believe. That is a conscious action, not a reflex action.
Reflexes are uncontrollable movements that happen almost instantly in response to a stimuli. A reflex arc, a neuronal circuit that controls reflexes, is where reflex activities takes place.
We can move immediately without thinking or using our brain for example if you touch a hot kettle you immediately pull your hand. In that case, you didn't use your mind in thinking if you will get it or not. you just pull your hand immediately because of the reflex action.
