Why are neurons called excitable cells?


Why are neurons called excitable cells? Mention special features of the membrane of the neuron?


Neurons are called excitable cells because they have an electrical potential difference

1. During the resting stage of the neuron, it has a sodium-potassium ion pump (i.e., Na+- K+ ion pump).

2. A change in the potential difference spread changes in the entire neuron

3. Stimulus in normally obtained in a place known as trigger zone in which sodium ions (i.e., Na+ ions) are abundantly present.
