an action potential moves along the neuron
Heat flow determines how hot or cold something feels when you touch it.
Thermal conductivity most determines how hot or cold something feels when you touch it. The nerve endings in your skin determine what is hot and cold when you touch it.
an action forms
Thermal conductivity most determines how hot or cold something feels when you touch it. The nerve endings in your skin determine what is hot and cold when you touch it.
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.
It is natural for the brain to respond of touch something too hot to handle by pulling the fingers away from it.
The Papillary is the upper layer of the dermis that has ridges and valleys causing finger prints. It has receptors which communicate with the central nervous system, these include touch, pressure, hot, cold and pain receptors.
Your nerves will send a message to your brain and your brain quickly sends a message back telling you to stop touching the hot or cold object,and that's your answer.
the body turn hot
This is an example of heat transfer through conduction. When you touch something hot, the heat from the object is transferred to your skin through direct contact, causing a burn.
A thermos would measure the net molecular motion, which is translated into heat. How hot something is. How cold something is is all relative to our sense of touch.
