Hint: Human nervous system is a very complex system. It is a part of the body that organizes its behavior and transfers signals to the body organs. In vertebrates, it contains two main types of the nervous system that are central nervous system (CNS) and peripheral nervous system (PNS).

The anatomy of neurons consists of:
(I) Cell body
(II) Dendrites
(III) Axon
(IV) Myelin sheath cells
(V) Nodes of Ranvier
(VI) Axon terminal bundle

We know that our whole body involves a huge amount of neurons or nerve cells and every part of the body is connected with these nerves and plays a vital role in the body's functioning. Nerve cells are also called neurons which are very important components or active components of our nervous system. They can communicate with each other as well as to other cells by electrical and chemical signals (nerve impulses). These signals in turn allow the effector organs to respond towards the appropriate stimuli. Neurons/nerve cells are the individual specific cell structure that is firstly involved in the process of information transmission. Neurons/nerve cells are found in the brain, spinal cord, and peripheral nervous system, it is a structural and functional unit of the nervous system.

Here it is described the three major functions of human nerve cells:
- Nerve cells are present in our brain, spinal cord, and peripheral nerves. Nerve cells transmit the information to the brain from different organs and vice versa. It has full control over all body functioning.
- Neurons are the basic unit of the nervous system. It has been carrying nerve signals from the brain to different organs and transmits the messages to the overall body.
- It is dedicated to carrying messages or information while the endocrine system delivers chemical integration by secreting hormones.

Note: Our nervous system is two types of the central and peripheral nervous system. Neurons or nerve cells are the active components of the nervous system. It majorly works as a signal molecule and transfers information from the brain to the other effector organs.
