One important aspect of reflex action is to help protect us without having to think. Reflex actions are involuntary and quick. They are done to meet an emergency and occur at the level of the spinal cord. Examples include the gag reflex clearing unplanned foreign objects or your eyelid closing when something gets near your eye.
The Pupillary Light Reflex and the Corneal Reflex (or Blink Reflex) are two important reflexes because the Light Reflex prevents damage to eye compopents related to over exposure to light and also helps the eye to accommodate visually, when there is less light; The Blink Reflex prevents objects from entering the eye and lubricates the eye. Also, breathing and heart beat are thought to be reflex actions.
Reflex actions do not require thinking, nor do the actions of involuntary muscles.
Reflex Arc
Advantages of reflex action it prevents us from getting injury because when we touches a hot object it can harm our hand and can cause injury we pull our hand quickly because of reflex action it prevents us from injury by taking immediate action
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.
Fish do have reflex actions.

Reflex actions are not controlled by the brain.
spinal cordautotomicspinal cord in the central nervous system controls reflex arc and reflex action.
reflex action is an involuntary action which means to do something physically whereas voluntary action means to do something mentally
Reflex actions do not require thinking, nor do the actions of involuntary muscles.
Involuntary and reflex actions
Most of them are controlled by the spinal column.
LUCY
An involuntary action is a body process that occurs automatically regardless of external stimulus. In contrast, a reflex is an automated response to an external stimulus.
Man's mind makes him responsible for his actions.
The impulse in a reflex action goes directly from the sensory neuron to the inter neuron to the spinal cord, which allows for faster actions.
