They occur at the postsynaptic dendrite in response to presynaptic neuron firing and release of neurotransmitter, or may occur in skeletal, smooth, or cardiac muscle in response to nerve input. The magnitude of a graded potential is determined by the strength of the stimulus.

WebIn addition to letting you consciously process the threat, your nervous system triggers involuntary responses, like an increase in heart rate and blood flow to your muscles, intended to help you cope with danger. All of these processes depend on the interconnected cells that make up your nervous system. WebThis is called the all or none law. Let’s say that we are electrically stimulating a muscle fiber. We begin with a low amount of stimulation that does not reach the threshold to produce a … WebApr 5, 2024 · It is important to note that the action potential is an all-or-nothing process and that signals are not partially transmitted.
