Effects of massage
massage techniques, acting on the fabric, causing excitation of mechanoreceptors.Mechanoreception includes a number of qualities arising sensations: pressure, touch, vibration and tickling that are associated with the presence of four types of skin receptors.
type I receptors - receptors pressure (force sensors), whose function is to measure the strength of mechanical stimulation of the skin, or the depth of its indentation.These receptors show the duration of pressure exerted.
type II receptors - touch receptors (velocity sensors).Their function is to determine the speed of the mechanical irritation and its change, that is, the characteristics of the mechanical irritation of the time.
type III receptors - receptors acceleration (vibration).Their function - determining the acceleration of skin displacement.
type IV receptors - receptors that provide the appearance of a tickling sensation.They react to the movement of the stimulus on the body, and in this case we are dealing with a psycho-physiologica
In addition to these types of receptors in the skin, there are mechanosensitive free nerve endings.Some of them are thermal receptors, others serve nonitseptorami (pain receptors).
Pacinian corpuscles (Vater-Pacini) are acceleration sensors, they are also called TP receptors.Taurus Mays inequality - speed sensors, also called tactile corpuscles meysnerovymi - located only in areas of the skin without hair (palms, soles, etc...).In the hair-covered skin of speed sensors take the form of the receptors of the hair follicles.Sensors in the intensity of skin devoid of hair are cell complexes or Merkel discs.In the deep layers of the skin (covered with hair and without hair) found other intradermal receptors - Ruffini corpuscles.
to all the above fit mechanoreceptors afferent nerve fibers at a rate of impulse conduction 30-70 m / s.
Skin contact, which is any of the massage techniques, excited receptors virtually all types of massaged area, but mostly stimulated by those that are most appropriate to the type of massage techniques.For example, the application of vibratory massage techniques advantageously excited vibration receptors (acceleration), when stroking -.. Touch receptors (velocity), etc. This fact explains the need to use all of massage techniques, as well as the possibility of multidirectional massage effect on the excitability of the nervous systemdepending on the strength, duration and rate of application of various methods.Mechanical irritation
deforming capsule receptors to cause stretching of the shell, causing a change in its permeability to sodium ions, which in turn leads to lower resting membrane potential and the potential of generating a prescription, which is transmitted on afferent nerve fibers.As a result, the process time and sequential summation of receptor potentials in the nerve fiber action potential occurs, which goes back to the roots of the corresponding segment of the spinal cord.Further, as part of lemniskovogo and spinal-thalamic tract impulses get into the brain in the somatosensory cortex.
