Reflex and Pupil Reflex
The adjustment reflex and the pupil's light reflex were two important physiological reflexes. The reflex of accommodation was a series of changes in the eyes in order to see nearby objects, such as the bulging of the lens, the narrowing of the pupils, and the convergence of the eyes. The pupil's light reflex was even more interesting. When light shone on one side of the eye, the illuminated pupil would shrink. This was the pupil's light reflex. It could protect the eyes from strong light and regulate the amount of light entering the eyes. Read more exciting novels for free
What are the physiological characteristics of the pupil's light reflex and near reflex
Pupil light reflex is the normal reaction of the pupil to the strength of light. It has the following physiological characteristics: - When the light was strong, it would cause the pupils to shrink rapidly. It was divided into direct light reflection and indirect light reflection. Direct light reflection was caused by the pupil shrinking when light directly shone on it, while indirect light reflection was caused by the pupil shrinking when light shone on one eye. It also has a bilateriality effect, that is, when one side of the eye is illuminated, in addition to the pupil shrinking of the illuminated eye, the pupil of the other side that is not illuminated will also shrink (mutual induction of light reflection). Some diseases, such as optical Neurisy, Optic Atrophy, chronic uveitis, Optic Canal fracture, etc., can cause the pupil's light reflex to weaken. Near-reflex was a type of pupillary reflex. Its physiological characteristics were that when the eyes looked at a near object, the pupils would shrink, accompanied by the lens becoming protruding and the visual axis of the two eyes converging to the side of the nose. This reflex process was controlled by the accessory nucleus in the oculnar nerve, so that the image could clearly fall on the retina to ensure the accuracy of vision. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Pupil light reflex examination slow
There were many reasons why the pupil was slow in examining the light reflex. One was the side effects of drugs, such as sedatives and antidepresses, which might affect the pupil's response to light, making it less sensitive to light. The other was the nervous system problem. The pupil's response to light was controlled by the nervous system such as the optical nerve and the brain stem. If these nerves had problems, such as optical neurosis, cerebral vasodilasis, or acquired nervous system diseases, it might cause the pupil's response to be less sensitive. Third, there were refraction problems, such as sore corneas and crystallites, which could affect the process of light entering the eye, thus affecting the pupil's response to light. Fourth, there were damage or pathological changes to the pupil or corneas, such as crystallites, rheumatism, or eye trauma. In addition, diabetes could also be one of the causes. When it was discovered that the pupil's light reflex was slow, a comprehensive analysis and diagnosis was needed based on the patient's specific conditions. Usually, a comprehensive assessment of the patient's health status was needed to determine the exact cause and give effective treatment. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
What medicine can make pupil reflex disappear?
Pilocarpine would cause the pupils to lose their light reflex. In addition, some cases of poisoning may also affect pupiliary reflexes. For example, in the case of organic phosphorus pesticide poisoning, chloridizing poisoning, pupil contraction, atropine poisoning, etc., may be accompanied by abnormal pupiliary reflexes, but it is not explicitly mentioned that it will directly lead to the disappearance of pupiliary reflexes. In the case of disappearance of pupil reflex, seek medical advice in time to find out the cause and treat it. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Is the anus reflex a deep reflex?
No, the anus reflex is shallow. It was mainly used for patients suspected to have damage to the spinal tract or cauda equina. It could be examined through specific methods, such as lying flat on the bed, raising the lower limbs straight, and using a cotton swab to cut across the perineal area. Under normal circumstances, the external anus constrictor would contract. It could also be used to prove the existence of innervation of the external anus constrictor structure through light needle or scratch stimulation. The patient could also be placed in the side lying position or the stone cutting position. The doctor would stand on the right side or in front of the patient and gently touch or tap the edge of the anus with a cotton swab. Under normal circumstances, the patient would feel a slight stimulation and have a constrictive reaction of the anus. Reflexes are caused by sacrospinal cord 4 - 5 or anococcygeal nerve damage. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Urination reflex is non-reflex
This statement was wrong. Urination was a complex reflex activity controlled by the central nervous system. The urine reflex was a physiological process that was controlled and participated in by the higher-level nerve center (the cerebral cortexes), but at the same time, it was also controlled and influenced by the lower-level nerve center (the spinal cord urine center). When the amount of urine in the bladder reached a certain level, it would produce a nerve impulse. This impulse would be transmitted to the cerebral hemisphere through the nerves, triggering the urge to urinate and activating the reflex to urinate. This was a complete reflex process. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Is a simple reflex called an unconditioned reflex
Yes, a simple reflex was called an unconditioned reflex. Unconditioned reflexes were the innate fixed nerve connection between external stimulation and organic response. The reflex arc was complete, and under the corresponding stimulation, it could cause a reflex reaction without the need for acquired training. For example, the simple reflex of withdrawing one's hand when it touched something hot was an unconditioned reflex. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Reflex principle
The principle of reflexivity was proposed by Soros. This principle was based on a phenomenon that existed in human affairs: when someone was involved in something, the participant's view of the world was one-sided and distorted (fallibility principle), and these distorted views would in turn affect the things related to the point of view. From the perspective of the connection between the participant's thinking and the situation they participated in, it could be decomposed into a cognitive function and a participation function. In the cognitive function, the participant's cognition depends on the situation; in the participation function, the situation is affected by the participant's cognition. The interaction between the two is called reflexivity, which can be expressed as a pair of recursion functions: y = f(x), x = q(y). In the field of economics, traditional theories often avoided or denied reflexivity, and Soros believed that a fundamental factor in the existence of reflexivity was human cognitive bias. In addition, Kant believed that the application of moral laws in practice was based on the principle of reflexivity. This principle meant that every moral law must become a basic principle, and every rule must conform to the basic principles that any rational person could accept. In the moral theory he constructed, he emphasized human free will and free decision. This principle was widely used in modern philosophy and promoted the development and progress of human thinking.

Is it better to play tennis with a single-reflex or a double-reflex?
There was no absolute difference between a DSLR and a DSLR. They each had different characteristics and needed to be chosen according to individual circumstances. From the perspective of stability, the double-back was more advantageous. It was relatively easy to hit the ball with more power. For novices who were not stable, the double-back was more conducive to maintaining the stability of the racket. This was why most tennis coaches now tended to teach the double-back. However, the flexibility of a double counter would be weakened, and the area that could be controlled would be relatively small. This placed a higher requirement on the ability to adjust one's footwork and predict. The advantage of an DSLR was that its movements were more elegant, agile, and more flexible. It could cover a larger area on the court and was more convenient to hit the ball quickly. Compared to a double-reflex, an DSLR could be faster by half a step. Its attack power was also relatively large, and it could play an advantage in high-speed fields such as grass. However, it was more difficult to learn the single-lens reflex, and it required a higher level of hand feel and upper body strength for the athlete. Moreover, when hitting the ball with a single-lens reflex, the one-arm backhand was not the mainstream play in tennis. For professional players, they tended to choose techniques that were more suitable for their own tactical system, while amateurs played for a variety of purposes. If they simply wanted to play well, the DSLR was a better choice. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Stimulate the throat muscle reflex to form a new reflex arc
The reflex arc consisted of five parts: the receptor, the sensory nerve, the reflex center, the efferent nerve, and the receptor. For the reflex of the throat muscle, when the throat is stimulated, the sensory organs in the throat first receive the stimulation and generate electrical signals (nerve impulses), which are transmitted to the reflex center through the sensory nerves. After the reflex center analyzed the incoming signal, it sent out an efferent command to the efferent nerve to reach the receptor (the muscles of the throat and other structures), thus causing the response of the throat muscles, which constituted a basic reflex arc. If a new reflex arc was to be formed, it often required certain conditions to be applied on the basis of the existing reflex arc. For example, if some kind of stimulation (For example, a specific chemical stimulation, a special mechanical stimulation, etc.) repeatedly with other irrelevant stimulation (such as a certain sound or light) at the same time on the reflex of the throat muscle. After many combinations, it was possible to form a new connection in the cerebral hemisphere or other relevant nerve centers. Therefore, on the basis of the original reflex arc, the original irrelevant stimulation was integrated into the reflex arc. When the irrelevant stimulation appeared alone, it could also trigger a similar reflex of the throat muscle, which formed a new reflex arc. However, the formation and change of reflex arcs were also affected by many factors, such as the development of the nervous system and the overall physiological state of the body. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
