In neuroscience, depolarization is an "all or nothing" response; what does that mean?
The neuron's intracellular charge must get more negative to meet a certain
threshhold in order to depolarize. If the neuron does not hit that threshold, then the
neuron will not fire

The neuron will either accept all signals, or none of the signals received. If the
neuron is ready to receive signals, then it automatically depolarizes and sends the
signals to the next neuron.

The neuron's intracellular charge must get more positive to meet a certain
threshhold in order to depolarize. If the neuron does not hit that threshold, then the
neuron will not fire

The neuron decides how much of the electochemical signals to send to the next
neuron; all or nothing

The correct answer is - The neuron's intracellular charge must get more positive to meet a certain  thresh hold in order to depolarize. If the neuron does not hit that threshold, then the  neuron will not fire

Explanation:

In neuroscience, the depolarization of neurons shows the all or none law which is also called as all or nothing response. It states that all action potentials have the same size and the potential or strength of a nerve cell does not depend on the stimulus strength as all are the same size.

If a stimulus reaches a particular threshold cell or fiber will fire so either it will fire or not cross the threshold this is all or nothing response or law and depolarization is an example of it.

Once you begin swallowing, the process becomes automatic. Your brain signals the muscles of the esophagus and peristalsis begins. Lower esophageal sphincter. When food reaches the end of your esophagus, a ringlike muscle—called the lower esophageal sphincter —relaxes and lets food pass into your stomach.
