at the end of each sensory nerve there is a sensor - hot, cold, pressure, vibration, etc.
If the sensors for hot are stimulated (hotter than what's around them (the rest of you),
then they cause the associated nerve to fire ... at the brain that's interpreted as hot.
an action potential moves along the neuron
The neuron in your finger senses the temperature first. It sends a signal to your brain, which then interprets the information and signals your muscles to move your hand away from the heat source.
A thermometer measures temperature. It tells you how hot or cold something is by showing a numerical value on a scale.
The first thing that happens when you touch something hot is the activation of specialized nerve endings called thermoreceptors in your skin. These thermoreceptors detect the change in temperature and send a signal to the brain through the neuron to alert you of the heat and trigger a reflex action like pulling your hand away.
You can tell if something is conducting thermal energy by observing if it becomes warmer to the touch when in contact with a heat source. Materials that are good conductors of thermal energy will quickly transfer heat from the source to the surrounding area. Metals like aluminum and copper are good conductors of thermal energy, while materials like wood and rubber are poor conductors.
Its something todo eith their sze of their index finger.
a thermometer
your finger can tell when an object is hot or clod because when a stimulus (the object) touches your skin, receptors transmit it to the brain and your brain sends a reflex reaction to let go
finger foods are delucious and hot or cold
The temperature of the object will provide this information.
The surest way to tell if your finger is broken is to have an x-ray done by a doctor. They will be able to tell for sure.
bugs, hair, mold, and finger
Temperature tells what degrees it is like how hot or cold something is

By asking her. Tell her something nice first about the way she looks, tell her she is beautiful, not hot though.
an action forms
if you spend more time outside, you will after a while get a feeling for how hot or cold it is outside just by peaking out the window. Good luck.
