Nerve signals are part of the communication that is essential for the transmission of actions and reactions. It is positive feedback that increases disruptive influences.
What is positive feedback?Positive feedback is a mechanism that increases or amplifies the series of reaction that is affected and influenced by its own results and processes. The output signal of the series act as an amplifying factor.
The nerve signals act as positive feedback by increasing the channels by a small amount of sodium that leads to an action potential, in the neurons to increase the disruptive influences.
The sodium ion of the nerve signaling causes the positive feedback loop to increase the ions entering the neurons which leads to more potential to be created.
Therefore, nerve signaling is an example of a positive feedback mechanism.
