Why are neurons called excitable cells?
Question:

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

Solution:

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.
