THE
SKIN IS A PROTECTIVE LAYER BETWEEN THE BODY AND ITS
EXTERNAL ENVIRONMENT.It works as a sensor to monitor
changes in exterior physical conditions.
Different kinds of situations such as heat,cold,pain,and pressure,provide&nb sp; different types of nerve cells ,in the skin .Thus ,the brain is sent the useful information of the happening outside the body ,and it in turn , command an action to different parts of the body.For example .when happen to hold a flower with a thorn and detect pain ,messages from the arm are sent to the spine .A spine sends this message to brain and brain commands the hand muscles to throw the flower.All this happen in less than one second .Thus ,these nerve cells prevent our body from damage or injury.Our skin feels the pressure and pain , so we feel when our finger is cut by knife.
