Skin receptors

 

Your skin and deeper tissues contain millions of sensory receptors. 
 
Most of your touch receptors sit close to your skin's surface. 
 

Light touch  

 

Meissner's corpuscles are 
enclosed in a capsule of 
connective tissue 

 

 They react to light touch and are 
located in the skin of your palms, 
soles, lips, eyelids, external 
genitals and nipples  

 

these areas of your body are 
particularly sensitive. 

Heavy pressure 

 

Paccinian corpuscules sense 
pressure and vibration changes 
deep in your skin. 

 

Every square centimeter of your 
skin contains around 14 pressure  
receptors 

Pain 

 

 

skin receptors register pain 

 

pain receptors are the most 
numerous 

 

each square centimeter of your 
skin contains around 200 pain 
receptors 

 

Temperature 

 

skin receptors register warmth and cold

 

 

each square centimeter of your skin contains 6 receptors for cold and 1 receptor for warmth

 

 

Cold receptors

 start to perceive cold sensations when the surface of the skin drops below 95 º F. They 

are most stimulated when the surface of the skin is at 77 º F and are no longer stimulated when the 
surface of the skin drops below 41 º F. This is why your feet or hands start to go numb when they are 
submerged in icy water for a long period of time. 

 

Hot receptors

 start to perceive hot sensations when the surface of the skin rises above 86 º F and are 

most stimulated at 113 º F.  Beyond 113 º F, pain receptors take over to avoid damage being done to the 
skin and underlying tissues. 

 

thermoreceptors are found all over the body, but cold receptors are found in greater density than heat 
receptors – most of the time of our environment is colder than our body temperature  

 

The highest concentration of thermoreceptors can be found in the face and ears so your nose and ears 
always get colder faster than the rest of your body on a chilly winter day
