Activity 3.1 : Sensing temperature through skin। Class 7। Thermoreceptors। Thermometer। Heat। NCERT।

Sensing temperature through skin. The primary sense organ is skin which contains specialized nerve cells called thermoreceptors. Thermoreceptors don't directly sense temperature; they detect changes in heat flow between the body and its environment. This means they don't give an absolute temperature reading but rather a perception of whether heat is being gained or lost. #temperature #temperaturemeasurement #temperaturesensor #thermoregulation #thermometer #heat #science #scienceactivity #experiment
