Quiz: Test Your Knowledge About Neuron As Structural And Functional Unit Of Neural System

Let’s start the quiz

A neuron is a microscopic structure and basic structural and functional unit of the nervous system. It is also known as a neurone nerve cell. It carries electrical impulses which transform the information from body to brain and brain to body. The three major parts of a neurone are cell body dendrites and Axon. The cell body contains cytoplasm with certain granular bodies called Nissl's granules and typical cell organelles. Let's take this quiz and check your knowledge, how much you know about the neuron as and functional unit of neural system?
