Your put your hand on a hot stove,and pull it away. How to your nerves recieve,interprets,the signals of heat?

Ok, Franko got it started-The action potential is propagated along the sensory axons, through the ulnar or other nerve (depending on exactly what part of your hand touched the stove), through the dorsal root ganglia (which is where the cell bodies for the sensory axon live) to the spinal cord.  There, they will release neurotransmitters at synapses with secondary sensory dendrites and cell bodies (which will send a signal on up the spinal cord to the brain) In addition, they will release neurotransmitters at synapses with interneurons, which synapse with motor neurons.  There motorneurons send axons to a number of muscles, such as the bicep.  A signal is generated at the motorneuron, sent down the axon, which then terminates on motor end-plates, which stimulate the muscle to contract, and thus pull the hand away.

You Probably gotten Overcome by heat

heat transfers from warmer objects to cooler objects. your tongue is warmer so the heat flows to the cold object; your tongue loses heat and becomes colder and sticks to the object.

your brain knows it is coming.  it is taking in the sensory information from your hands and the spot you are touching simultaneously, \n\neven when you know where someone else is going to tickle you, you dont know the exact movement of their hands,  (or tongues   ; p    )

That is how your body reacts to hot foods. There is no great explanation, but it is how your body reacts.

well naturally you are going to get heated up....

Thermoreceptors are receptors that are sensitive to temperature change. So, they respond to the heat input by either Heat-Promoting or Heat-Loss Mechanisms. In heat-promoting, the body will either vasoconstrict the blood vessels, increase the metabolic rare, and or cause shivering of the body. For Heat-Loss the body will dilate the blood vessels or cause sweating.

Okay: it's simple. Your blood chills when you suddenly get cold, right? Well, you get cold whenever your body temperature drops. Your body temperature drops during certain emotional activity in your brain. One emotion: fright. There you go! Or, i could answer like a complete jackass by saying a ghost is trying to possess you, but I'm not going to.   :)

Now, this answer depends on what you mean by Heat.  Strictly speaking Heat (symbol 'Q')is the energy transferred from one part of a substance to another, or from one object to another due to a change in temperature.  To give you an example, if you heat a spoon on a flame and then insert it in a glass of water, the latter will warm up since Heat moves from the hot spoon to the cooler water.  Heat is a measure of energy and so its units are Joules (J).  The amount of Heat energy transferred is calculated by the formula Q=mcdT (mass x specific heat capacity x change in temperature)\n\nNow, if you are still studying basic Physics, you might come across definitions of Heat which state that it is the Energy driving the vibrations and movement of molecules.  In further Physics this will be called "Internal Energy", symbol 'U'.  In fact, the internal energy of a body can either be changed by giving or taking Heat (with a temperature difference) and/or by doing Work (that is why if you rub your hands together they warm up, despite being at the same temperature).\n\nTemperature is a measure of the degree of hotness of an object (not a measure of the amount of Heat in it!).  So, if an object has a temperature of 0 degree Celsius, this means that this object is as "hot" as pure melting ice.  In the same manner, a stone at a temperature of 100*C is as "hot" as steam above boiling water, and so on.  So, temperature is really a comparison.  There is an Absolute Temperature Scale devised by Kelvin in 1848, who found out that the lowest possible temperature is -273*C.  At this temperature all molecular movement is thought to stop and therefore there cannot exist a place colder than a place where there is no Internal Energy, and hence no heat!  Therefore this temperature is called Absolute Zero, and a temperature scale starting from this point, 0 K(elvin) (=-273*C), was set up. (e.g. 10*C = 10 + 273 = 283K).

The brain is not involved in a reflex arc. I believe the signal only gets as far as the spinal cord. You pull your hand away from a hot stove before your brain can even register that it is feeling heat.

nerves? or can you be more specific? or thats juz the question?

I'd say hot, try and find something you're both going to be comfortable with and make sure you're not going to be disturbed. If it freaks either of you out, stop and put it down to experience!

They actuate a type of selonid \n1 should be Hot and 1 should be ground

maybe it senses the temp?-just a guess

heat is the measurement of thermal energy

It's not heat that rises, it's hot substances. Heat itself has no mass and does not care where the gravity is pointing. However, the density of substances will vary with temperature. Most substances have a decrease in density as the temperature of that substance rises.\n\nThis is why it appears as if heat rises from a fire or your stove. The heat you feel is actually hot air that rises due to the force caused by bouyancy. This bouyancy is a result of the fact that warm air is less dense than cold air.

The hot stuff in peppers is called capsaician.  It causes "ion channels" in your nerve cells to open.  They aren't special nerve cells; they are the regular heat-sensing nerve cells.  That is the same thing that high temperatures do.  So, your nerve cells think they are experiencing high temperatures and send that message to your brain.  Then, you say, "Ouch! Ouch! Give me some water, quick!"\n\nHowever water does not work because capsaician does not dissolve in water.  It will dissolve in fat or alcohol.  So, when you eat hot food, you should say, "Ouch!  Ouch!  Give me some tequila, quick, hombre!!"\n\nhttp://en.wikipedia.org/wiki/Capsaicin
