- Reflex action is the response of the central nervous system to a stimulus. Nerve impulses pass through the central nervous system, but are not recorded consciously.
- Standing, walking, jumping-virtually all movements, including movements of internal organs (such as those related to digestion), are triggered by reflex actions. The so-called "knee jump reflex" is the unconscious lifting of the calf when the tendon under the knee is hit. This is an example of a non-conscious, reflective action with a living thing. This reflex action can be excited at any time, and it is practically impossible to stop. Perceptual reflections and unconditioned reflections are easier to control. They may disappear when not needed. For example, when we see delicious food, the mouth is drooling. This is a conditional reflex caused by visual stimuli. Horses can move sideways because the rider applies pressure with their legs, or the horse canter because the rider increases the pressure on the saddle. These can be considered conditioned reflexes.
- Dressage includes a lot of training on specific conditioned reflexes. A lot of conditioned reflex
- As far back as the time of Galen, there has been a modern description of the so-called pupil reflection. Descartes proposed the idea of reflection in the 17th century, but it was not until 1736 that Astrik first proposed the word "reflection". He divided the reflection into sensory nerves. 3, the lower part of the central nervous system and the three parts of the movement, pointing out the difference between free movement and reflex action. In the 19th century, Johannes Müller introduced the concept of reflexes into the physiological system, thinking that reflex actions also pass through the brain, but do nothing in the brain. The in-depth study of reflex action is very meaningful for exploring the physiological mechanism on which psychological activities occur. [1]
