Question

Define Brain in more than 200 words.

Answer 1

 the brain isn’t the largest organ of the human body it is the most complex and controlling organ. It is amazing how complicated the brain is. The brain controls every action within and out of your body. The brain has main areas that contain different areas that have specific functions. For instance the basal ganglia holds the lentiform and the caudate. 
The brain isn’t just “THE BRAIN” it is actually a group of many parts. They help to inform the brain on the things going on with the human body. The brain is split in to two main parts, the left and the right hemisphere. The left hemisphere has about the same areas as the right hemisphere.

The corpus callosum is a bundle of nerves that connects the two hemispheres. The area that passes and processes information concerning touch, pain, temperature, and pressure on skin is the thalamus. The limbic system controls your behavior and emotions. It is involved in emotions such as fear, rage, pleasure, and sorrow. In the prefrontal area of the frontal lobe emotional traits are controlled. In the temporal lobe expressed behavior is controlled. The parietal lobe discriminates sensory. The occipital lobe is where visual interpretation takes place. Pons is a crossroad for nerves going up to the cortex, to the cerebellum and then down the spinal cord., The cortex is the outer gray area where thinking takes place. The olfactory cortex receives senses from the nose that it then sorts out. The area that identifies what we see by working out movements, colors, and shapes is the visual cortex. The area that receives taste senses is called gustatory cortex. The area responsible for analyzing data, performing memory functions, learning new information, forming thoughts, and making decisions is the cerebral cortex. The motor cortex is involved in muscle movement. The cerebellum is vital when carrying out complicated, skilled movements. It is much like a mini brain.

Answer 2

The brain is the part of the body which lets animals make sense of things. It gets input from sense organs, and changes behavior in response to this information. In humans, the brain also controls our use of language, and is capable of abstract thought.

The brain is the main control centre of the whole body.The brain is made up of a special type of cells. They are connected with each other and with the nerves in our body. In all animals the delicate brain is protected in some way. In ourselves, and all vertebrates, it is protected by the bones  of the skull.

Functions

The brain does the thinking, learning, and feeling for the body. For humans, it is the source of consciousness. The brain also controls basic autonomic body actions, like breathing, digestion, heartbeat, that happen automatically. These activities, and much else, are governed by unconscious functions of the brain and nervous system. All the information about the world gathered by our senses is sent through nerves into the brain, allowing us to see, hear, smell, taste and feel things. The brain processes this information, and we experience it as pictures, sounds, and so on. The brain also uses nerves to tell the body what to do, for example by telling muscles to move or our heart to beat faster.

This is generally true but some activity is caused by the spinal cord directly, for example, reflex actions do not involve the brain. In lower animals, a good deal is done without their brain being involved.

All vertebrates  have brains and, over time, their brains have evolved to become more complex. Some simple animals, however, like sponges, do not have anything like a brain. Segmented invertibrate  have ganglions in each segment, and a ring of nervous tissue around the alimentary canal at the front. This acts to bring sense data from the front into play with the movement of the body.
