Detailed explanation-1: -Sweating is not a reflex action. It is primarily a means of temperature regulation. But, salivation on seeing food, hand withdrawal because of the needle and blinking of the eyes due to bright light are all examples of reflex actions.
Detailed explanation-2: -For example, if you put your hand on a hot stove, a reflex causes you to immediately remove your hand before a “Hey, this is hot!” message even gets to your brain. Other protective reflexes are blinking when something flies toward your eyes or raising your arm if a ball is thrown your way.
Detailed explanation-3: -Blinking reflex: blinking the eyes when they are touched or when a sudden bright light appears. Cough reflex: coughing when the airway is stimulated. Gag reflex: gagging when the throat or back of the mouth is stimulated. Sneeze reflex: sneezing when the nasal passages are irritated.
Detailed explanation-4: -Coughing, yawning and blinking of eyes are examples of reflex actions.
