Diathermy- uses high frequency electromagnetic current to induce heat to deeper tissues used in surgery or physical therapy.
Thermoesthesia- is the ability of our body to distinguish between difference in temperature, when we touch two objects of different temperatures.
Thermogenesis- it is a mechanism by which our body produce heat , usually in response to cold climates.
Hypothermia- it is a condition in which our core body temperature drops below 35 degree celcius, usually occurs during exposure to cold climates.
Hyperthermia- it's is the opposite of hypothermia. In this condition, body temperature is more than normal due to prolonged exposure to hot climate and because of failed thermoregulation.
* Themoregulation is controlled by centres in hypothalamus in exposure to cold and hot climates.
* Thermogenesis occurs mainly because of shivering which is involuntary.
* Thermoesthesia is sensed by hot and cold receptors present in our skin and the impulses are carried to sensory cortex of brain through sensory pathways.
I hope this solves your query. In case you need anymore clarifications, leave a comment and I will get back to you.
