Expert Solution

Step 1

Neurons are the structural and functional unit of nervous system that is responsible for nerve impulse generation and transmission throughout the body. The differential ion concentration across the plasma membrane of neurons is responsible for the generation of this nerve impulses. Presence of specific iron channels play a critical role in this process.
