The Biophysical Modeling of the Human Tegument

Sensory organs are parts of our body, which collect and transmit information to the central nervous system about the outside world, and about the internal condition of our body. The body collects information by millions of microscopic structures, the so-called receptor cells. These can be found in almost all parts of the body, skin, muscle, joints, internal organs, in the walls of blood-vessels and in specialized organs such as the eye or the inner ear. There are numerous types of receptor cells in the skin. Some of them register mechanical stress or pressure, others the position and displacement of sensory hairs. Different stimulation cause different sensations, such as pain, tickling, hard or light pressure, heat or cold. The nerve fibres connected to the receptor transform stimuli above threshold into sequence of actions potentials. We modelling the action potential in the mathematical equation. Although our current knowledge regarding the mechanisms of pain development is incomplete, a number of pain-related phenomena have been discovered, which bear importance from both pathobiophysical and clinical aspects. Skin is an important receptive field, due to the numerous and various terminations of the cutaneous analyser which informs the nervous centres on the proprieties and phenomena that the body gets in contact with.
