2第二节神经反射作用（2secondnervereflexaction）

1、2 第二节神经反射作用(2 second nerve reflex action)second nerve reflex actionthe massage of the foot reflex area is essentially a physical stimulus applied to certain sensitive points or sensitive zones on the body surface (the pressure acting on the local tissue of the body) according to the theory of nerve

2、reflex, this external stimulus is bound to cause a regular adaptive response to the organism.the pressure exerted on the foot reflex area acts on the surface of the foot, and affects the skin. there are many tactile receptors, nerve pressure receptors, pain receptors, capillaries and capillaries in

3、the spinal cord because the pressure is applied to massage, the connective tissue and deep muscular tissue in the cortex are squeezed, so that the blood vessels and lymphatic vessels are squeezed when the pressure reaches a critical intensity (threshold), tactile and tactile receptors begin to trans

4、mit nerve impulses through the somatic afferent nerve to the nerve center if the compression of the larger, a plurality of sensors of touch, these receptors of nerve impulses to the central nervous system, superimposed into strong nerve impulses: at the same time, because the massage caused strong t

5、enderness, pain receptors to transmit strong central nerve impulses: and because of the blood vessels and lymphatic vessel, feeling for vascular and lymphatic vessels through the visceral afferent nerve to the central transmission of nerve impulses in short, these afferent impulses inthe central poo

6、l, the formation of a strong impulse to the powerful central nerve stimulation were analyzed comprehensively after central nervous system excitement, nervous excitement and impulse to the efferent nerve through effector (related organs) to respond accordingly. this is the process of nerve reflex act

7、ivity we believe that foot massage plays a positive role in the body, which is based on the neural reflex activity foreign medicine foot massage method which is called reflection therapy (reflexology), the sensitive area of the foot and body organs corresponding to the called reflection area (reflex

8、es), it is also based on this reason. we will try to explore the mechanism of foot reflexology by using the neural reflex theory as the basic point of departurefirst, the foot massage produces a strong nerve impulse to the nerve center, while blocking the other pathological impulses into the nerve c

9、enter, the vicious circle of pathology into a virtuous circle, thus eliminating the role of disease health care because of the internal and external causes of the disease, the function of an organ in the human body is not normal or there is a certain pathological state this abnormal or pathological

10、state stimulates the internal receptors, excites them and sends impulses to the nerve center. this pathological impulse produces some pathological foci in the nerve center, causing some pathological reflex and making the effector react passively. this negative reaction is then fed back to the center

11、, forming a vicious circle that worsens the condition of the organism the benign stimulation of massage on the foot reflex area can break the vicious circle, and turn it into a virtuous circle, which is conducive to the rehabilitation of the body. there are several explanations for the mechanism:1,

12、by foot massage produced by nerve impulses, spread to the central nervous system after the formation of a new exciting center, according to the 1aw, in the course of a reflection, some other reflection that is restrained, so that the original pathological excited kitchen was inhibited2, the tenderne

13、ss of foot massage improves the pain threshold of other parts of the body, and also increases the threshold of the pa in receptor originally, the pathological impulse that makes the receptor excited becomes below the critical intensity (subthreshold), while the stimulation below the critical intensi

14、ty can not produce the impulse afferent nerve center3, gate theory: the central nervous system can only handle a limited amount of information at the same time foot massage stimulation, a large amount of information transmitted to the nerve center, so that the nerve center is poor, difficult to deal

15、 with other information at the same time(as the telephone routes are full, the phone doesn，t work)therefore, the gate was closed, and the afferent pathway of pathological impulse was blockedseveral explanations above all but still need it stands to reason，rigorous scientific proof, this is not an in

16、-depth discussion.two, applying massage physical stimulation by reflex activity, start the adjustment mechanism of the body's internal organs, activation function, the release of various treatment factors, thus preventing and curing diseases, maintenance of healththe human body has its own poten

17、tial, and has a wide range of adaptability to changes in the internal environment and external environment the adult heart output, for example, is 5 liters per minute but in strenuous exercise, it can reach more than 25-35 liters per minute the lungs of normal adults have 300 million alveoli, with a

18、 total diffusion area of 70 square meters, but only 40 square meters under normal conditions the area of the human cortex is 2200 square centimeters, and there are 14 billion neurons, and its potential is enormoushuman body has natural defense ability for various pathogenic factors of internal envir

19、onment and external environment after being damaged, it has a certain self repair ability foreign body stimulation of the nasal mucous membrane sneeze into the trachea foreign body will cause coughing, eye blinking, tears stimulation caused by foreign objects, eating rotten things to the nausea and

20、vomiting, sneezing and coughing and blinking, vomiting, are some instinctive defensive reflex when the skin is bleeding, pain caused by reflex will make small blood vessels to reduce the amount of bleeding, bleeding at the same time, will be gathered a large number of white blood cells and platelets

21、, the former is to protect the body from bacteria, the latter is to make the blood quickly to avoid excessive loss of blood coagulation. as long as you' re not infected, the wound can heal itself gradual1y. broken bones, such as plaster bandages, can also grow wel 1. most of the liver is removed

22、, and it can regenerate to the original size in a short timethe human body is so wonderful, it objectively exists a flexible mechanism of self regulation, so that people can adapt to the complex changes of the inner and outer environment for survival and development. effect of foot massage, but this

23、 massage is the use of external stimulation, to activate the regulation mechanism of human body in various organs and tissues, stimulate the body potential, give full play to the body，s own defense capability and self repair ability, in short, to mobilize all positive factors in the human body, to o

24、vercome pathological factors, namely chinese medicine fuzheng evil method say, that's all.for the human body, foot massage is a benign stimulus because it is generally not hurt (unless the position and intensity of inappropriate and no side effects (periosteal), it is believed that the neural re

25、gulation of the body from non steady state in steady state is relatively easy, will break into the steady unsteady state is very difficult therefore, it can only restore the function of abnormal organs to normal, but not to the normal functioning of the body organs become abnorma 1. but foot massage

26、 is also a sort of noxious stimulation. because it can make local tissue compression, displacement, deformation, blocked blood circulation, make people have a strong sense of pain, which can make feel strongly motivated by a nerve impulse, these impulses may cause a series of nonspecific defense rea
