Draw a neat and labeled diagram of a neuron and answer the following questions :

(a) What are the two main parts of a neuron?

(b) Is this structure unicellular or multicellular?

(c) Which part of the neuron contains nucleus?

(d) Name the two parts of the human body where neurons are found abundantly.

(e) How are neurons significant to us?

Labeled diagram of a neuron is shown below:

(a) Axon and Cyton

(b) Unicellular

(c) Cyton

(d) Brain and Spinal cord

(e) Neurons are significant to us as they are the fundamental building blocks of the nervous system. Neurons carry impulses between sense organs and brain or spinal cord as well as between themselves. They keep us informed about the outside world and bring about control and coordination in our body. They also help in regulating our involuntary activities.
