Answer

Reflex is involuntary and a sudden response to stimuli. It happens to be an integral component of the famed survival instinct. Most of the common reflexes are a response to all the well trained, accumulated knowledge of caution that we have internalized. It could be anything and ranges from the reflex action of abruptly withdrawing the hand as it comes in contact with an extremely cold or hot object. This action is termed as the reflex action. It has a subtle relation with instinct

Answer

Reflex action = Involuntary action

Explanation:
Reflex action is an automatic and involuntary response to a stimulus. It is a rapid and unconscious action that occurs without conscious thought or decision-making. Reflex actions are mediated by the spinal cord and do not involve the brain. They help in protecting the body from potential harm and maintaining homeostasis.

Characteristics of reflex actions:
1. Involuntary: Reflex actions are not under conscious control. They occur automatically and without any conscious effort or decision-making.

2. Rapid: Reflex actions are quick and occur within a fraction of a second. They help in providing immediate responses to stimuli.

3. Unconscious: Reflex actions occur without any awareness or conscious perception. They do not require the involvement of the brain or conscious thought processes.

4. Protective: Reflex actions help in protecting the body from potential harm. For example, when we touch something hot, the reflex action of pulling our hand away occurs to prevent burns.

5. Stimulus-specific: Reflex actions are specific to the type of stimulus. Different reflexes are triggered by different stimuli. For example, the knee-jerk reflex is elicited by tapping the patellar tendon below the knee.

6. Consistent: Reflex actions are consistent and predictable. They occur in the same way every time a specific stimulus is applied.

Examples of reflex actions:
1. Blinking: When an object comes too close to the eyes, the reflex action of blinking occurs to protect the eyes from potential damage.

2. Sneezing: When irritants such as dust or allergens enter the nasal cavity, the reflex action of sneezing occurs to expel them.

3. Coughing: When the airway is irritated or obstructed, the reflex action of coughing occurs to clear the airway.

4. Withdrawal reflex: When the body comes in contact with a painful stimulus, such as touching a hot object, the reflex action of pulling the body part away occurs to prevent injury.

5. Pupillary reflex: When light is shone into the eyes, the reflex action of constriction of the pupils occurs to regulate the amount of light entering the eyes.

Therefore, reflex action is an example of an involuntary action as it occurs without conscious control or decision-making.

Answer

Reflex action does not pass directly into the brain, but synapse in the spinal cord.

Answer

Reflex action is an involuntary action as in reflex action the action in our body take place without thinking means no thinking take place in reflex.
