Reflection arc break

The structural basis of reflex activity is called the reflex arc, and includes the receptor, afferent nerve, nerve center, efferent nerve, and effector. In short, the reflex process proceeds as follows: certain stimuli are felt by certain receptors, and the receptors are excited; excitement is transmitted to the center through afferent nerves in the form of nerve impulses; through the analysis and comprehensive activities of the center, the center produces Excitement; central excitement reaches the effector via a certain efferent nerve, causing the effector to perform corresponding activities. If the center is suppressed, the original outgoing impulse of the center weakens or stops. Under experimental conditions, artificial telestimulation can directly cause afferent nerves to act on afferent nerves. However, under natural conditions, reflexive activities generally require a complete reflection arc to be tested. If any link in the reflection arc is interrupted, the reflection is Can't happen.
