1. A neuron is a nerve cell that is the basic building block of the nervous system. Neurons are similar to other cells in the human body in a number of ways, but there is one key difference between neurons and other cells. Neurons are specialized to transmit information throughout the body.

These highly specialized nerve cells are responsible for communicating information in both chemical and electrical forms. There are also several different types of neurons responsible for different tasks in the human body.

Sensory neurons carry information from the sensory receptor cells throughout the body to the brain. Motor neurons transmit information from the brain to the muscles of the body. Interneurons are responsible for communicating information between different neurons in the body.

 

2. The nervous system consists of the brain, spinal cord, sensory organs, and all of the nerves that connect these organs with the rest of the body. Together, these organs are responsible for the control of the body and communication among its parts. The brain and spinal cord form the control center known as the central nervous system, where information is evaluated and decisions made. The sensory nerves and sense organs of the peripheral nervous system (PNS) monitor conditions inside and outside of the body and send this information to the CNS. Efferent nerves in the PNS carry signals from the control center to the muscles, glands, and organs to regulate their functions.

The Brain

The brain (cerebrum) is the enlarged and highly developed mass of nervous tissue that forms the upper end of the central nervous system. The average adult human brain weighs about 1400 g and is continuous below with the spinal cord. The spinal cord is the portion of the central nervous system enclosed in the vertebral column, consisting of nerve cells and bundles of nerves connecting all parts of the body with the brain. It contains a core of grey matter and is enveloped in three layers of membrane (the meninges) and extends from the medulla oblongata in the skull to the level of the second lumbar vertebra.

The brain is a complicated organ which consists of grey matter or nerve cells on the surface, and white matter or nerve fibers in the center. It contains many important nerve centers which make it not only the largest but the most important part of the brain.

The functions of the brain. The role of nervous system in our body is often compared to that of a centralized computer which controls the functioning of an entire system. The nervous system plays an important role in the smooth functioning of the different parts of our body. It is basically a complex network of cells with specialized functions. These cells communicate with each other by means of electrochemical waves. The neurons are the important components of the nervous system.

Central nervous system is the seat of all sensation due to the bringing in of the stimuli from the tissues by afferent fibers to the sensory centers of the brain. These stimuli pass through three or more afferent neurons before they reach the sensory centers of the cerebrum. Central nervous system controls all movements of voluntary muscles – muscles of the head, limbs and trunk. Movement is due to nerve stimulus. Movement is classified as voluntary and reflex one. The brain is the special seat of all the special senses – sight, hearing, smell, touch, and taste. The brain is the seat of all the higher mental powers – reasoning, will power, consciousness, memory, emotions, etc. The brain also controls the vital functions of the respiration and circulation, the controlling centers being located in the medulla.
