20 lines about the brain please, I will mark them as best answer​

Answer 1

Answer:

BRAIN :-

1. The brain is the part of the body which lets animals make sense of things.
2. The brain is the main control centre of the whole body
3. In humans, the brain also controls our use of language, and is capable of abstract thought.
4. The brain is made up of a special type of cells
5. All vertebrates have brains
6. In mammals, the brain is made of three main parts: the cerebrum, the cerebellum and the brainstem
7. The surface of the cerebrum is the cerebral cortex, which all vertebrates have.
8. The volume of the human brain is very large, compared to that of most other animals
9. It is constantly dealing with hundreds of messages from the world around you, and from your body, and telling your body what to do.
10. It gets the messages from your senses - seeing, hearing, tasting, smelling, touching and moving. The messages travel from nerve cells all over the body. They travel along nerve fibres to nerve cells in the brain.
11. Cranial nerves carry messages to and from the ears, eyes, nose, throat, tongue and skin on your face and scalp.
12. Doctors and scientists have found that different parts of the brain are in charge of different things
13. our brain has around 100 billion nerve cells
14. It also has 1,000 billion other cells, which cover the nerve cells and the parts of the nerve cells which form the links between one cell and another, feed them and keep them healthy.
15. The front of the human brain is larger than any other animal's, even the dinosaur's
16. The adult brain weighs about 1.5kg
17. The brain stores all sorts of things in the memory including facts and figures and all the smells, tastes and things you have seen, heard or touched.
18. The left side of your brain is usually better at problem solving, maths and writing.
19. The right side of the brain is creative and helps you to be good at art or music.
20. Your brain can also find things that you have remembered---like how to spell ce-re-bell-um.

Answer 2

• The human brain is the central organ of the human nervous system, and with the spinal cord makes up the central nervous system.
• The brain consists of the cerebrum, the brainstem and the cerebellum.
• It controls most of the activities of the body, processing, integrating, and coordinating the information it receives from the sense organs, and making decisions as to the instructions sent to the rest of the body.
• The brain is contained in, and protected by, the skull bones of the head.
• The cerebrum is the largest part of the human brain.
• It is divided into two cerebral hemispheres.
• The cerebral cortex is an outer layer of grey matter, covering the core of white matter.
• The cortex is split into the neocortex and the much smaller allocortex.
• The neocortex is made up of six neuronal layers, while the allocortex has three or four.
• Each hemisphere is conventionally divided into four lobes – the frontal, temporal, parietal, and occipital lobes.
• The frontal lobe is associated with executive functions including self-control, planning, reasoning, and abstract thought, while the occipital lobe is dedicated to vision.
• Within each lobe, cortical areas are associated with specific functions, such as the sensory, motor and association regions.
• Although the left and right hemispheres are broadly similar in shape and function, some functions are associated with one side, such as language in the left and visual-spatial ability in the right.
• The hemispheres are connected by commissural nerve tracts, the largest being the corpus callosum.
• The cerebrum is connected by the brainstem to the spinal cord.
• The brainstem consists of the midbrain, the pons, and the medulla oblongata.
• The cerebellum is connected to the brainstem by pairs of tracts.
• Within the cerebrum is the ventricular system, consisting of four interconnected ventricles in which cerebrospinal fluid is produced and circulated.
• Underneath the cerebral cortex are several important structures, including the thalamus, the epithalamus, the pineal gland, the hypothalamus, the pituitary gland, and the subthalamus; the limbic structures, including the amygdala and the hippocampus; the claustrum, the various nuclei of the basal ganglia; the basal forebrain structures, and the three circumventricular organs.
• The cells of the brain include neurons and supportive glial cells.
• There are more than 86 billion neurons in the brain, and a more or less equal number of other cells.
• Brain activity is made possible by the interconnections of neurons and their release of neurotransmitters in response to nerve impulses.
• Neurons connect to form neural pathways, neural circuits, and elaborate network systems.
• The whole circuitry is driven by the process of neurotransmission.

Hope this helps you
