What are the properties of 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.

What are two example of reflex actions and their importance?

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.


What respond to a stimulus that does not involve the brain?

It is called a reflex and does not involve the brain, but instead, the spinal cord. So, in effect, the spinal cord can also 'think' and process information, though not quite the level of complexity as the brain, especially the cerebral cortex. But, that is a good thing. If I touch a hot stove, my spinal cord will send out a signal to pull my hand off well before my 'brain' feels the heat. There is a lot of survival value to reflex arcs that are essential to survival that do not include the brain.
