Answer 2

Answer:

A few examples of reflex action are: When light acts as a stimulus, the pupil of the eye changes in size. Sudden  withdrawal of hand or leg when pricked by a pin. Coughing or sneezing, because of irritants in the nasal passages.

The sequence of events occuring during sneezing are:

 

1. Nerve endings located in the nasal passage identifies the irritant entered in the nose.

2. Receptor sends the information or nerve impulse to the sneezing centre located in the brain stem.

3. Brain stem sends instructions to the lungs or diaphragm for response.

4. Diaphragm moves abruptly and the chest muscles contract in response to the instructions received.

5. Air blows out from nose and mouth rapidly.

6. Sneezing occurs in response to the irritant to a blow or someone stamping the leg.
