What does medicine mean?
summary
What does medicine mean? Let's get to know from the doctor's explanation. It is undeniable that defecation is a normal and indispensable physiological activity, and the meaning of defecation is to sound the horn of defecation. As the saying goes: defecate impassability, worry, defecate a pass all relaxed. What does medicine mean? I'd like to share my views with you.
What does medicine mean?
First of all, defecation means that after the intestinal contents move to the rectum, they are produced by mechanical stimulation of the defecation receptors here. The contents of intestines are usually stool, but for friends with frequent bowel movements, we should be wary of false bowel movements. False defecation means that factors other than defecation (including neural factors) stimulate defecation receptors to produce defecation reflex or transanal discharge, which is not dominated by defecation.
Secondly: proctitis disease, rectal mucosa prolapse, rectal or adjacent tissue tumor, spinal neuropathy can produce false stool, mental factors can participate in any of the above diseases, do evil. Next, I will lead you to look for clues of disease and prevent it.
Finally: after the formation of feces, due to colonic peristalsis, all parts of the colon contract and push the feces to the distal colon. This peristalsis usually starts from the liver flexure, 2-3 times a day, and advances to the left colon at the speed of 1-2 cm per minute, and then to the sigmoid colon for storage. However, after eating or getting up in the morning, the total peristalsis of the colon is caused by gastrocolic reflex or postural reflex, which can be pushed at a speed of 10 cm per hour. If there is feces in the sigmoid colon, the feces can enter the rectum. When enough feces are accumulated (about 300 g), a certain pressure on the intestinal wall will cause defecation reflex.
matters needing attention
As the defecation reflex is controlled by the cerebral cortex, consciousness can control defecation. Anus to maintain a certain tension, so that the anus closed, prevent feces, liquid, gas leakage, this effect is called defecation control effect. Defecation control is a complex reflex activity, which is completed by sensation, reflex and muscle activity. If environmental conditions do not permit, when there is a feeling of defecation and it is unable to defecate, the downward impulse of the high-level center of defecation suppresses the low-level center of defecation, enhances the contraction of sphincter, closes the anus like a control gate, and causes the sigmoid colon to relax reflexively. The feces in the rectum immediately return to the sigmoid colon, so that the defecation will disappear temporarily. But if you often or for a long time inhibit defecation, can make rectum to fecal stimulation of the third sex reduce or disappear, feces stay in the large intestine too long, water is absorbed too much and make it dry, can produce constipation. Therefore, you can't control defecation at will. It's better to have defecation.
