Reflex and Pupil ReflexThe 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.

Urination reflex is non-reflexThis 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.

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.

Is a simple reflex called an unconditioned reflexYes, 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.

Reflex principleThe 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.

What is reflex fiction?Well, reflex fiction is really interesting. It's the kind of fiction that doesn't just tell a story in a straightforward way. Instead, it might make you think about how the story is being told, like the author might break the fourth wall and address the reader directly, or it could have characters who are aware that they are in a story. This can create a really unique reading experience as it blurs the lines between the fictional world and the real world of the reader.

Reflex lens photographyThe works shot with a reflective lens had a unique effect. For example, the wild cypress flowers in Northeast China shot by Nikon Z8 with NiSi 250mm F5.6 ReflexTF lens, as well as the peony flowers under the backlighting shot by this lens, presented a hazy, dreamy and gentle effect; peony flowers and barnyard grass could be covered with dewdrops, and the roadside flowers under the backlighting with the morning sun sprinkled on them were particularly dazzling; The picture of the path in the pear tree garden was taken through this lens with five multiple exposure shots. The picture was soft and transparent, with comfortable retro warm colors. It looked calm, clean, and more like an oil painting atmosphere. These works could display the unique haziness effect of the lens. When the point light source in the background or when there were dewdrops on the grass or ripples on the river under the backlighting, the highlights would form a charming ring-shaped defocused " donut ". The more highlights outside the depth of field, the brighter the donut effect would be. At the same time, it could also show the retro and unrestrained two-line effect. Its tone and color were unique, giving it a sense of oil painting and presenting an artistic two-line touch. The soft, retro oil painting's tones and shades gave off a dreamy effect.
