What are the largest and the smallest parts of the human brain?
The cerebrum is the largest and most developed part of the brain. It, unfolded, has the surface area of four school desks. It makes up 85% of the brain's weight. It's the center of judgment, reasoning, complex learning, abstract thinking, association, interpretation of sensory information, speech, learning and memory, and also controls voluntary actions, like how you think and move. It's made of two halves, the left and right cerebral hemispheres.

What system are involved in getting glucose to your brain?
Certain hormones act upon the liver to release glucogen and it is converted into glucose which then gets circulated into the brain cavity. Asteocytes are attached to this glucose enriched blood and the glucose is then chemically transported to the brain where it is readily required.
So we can survive in the world. So we can invent stuff to make life easier. So we can create a better world.

Essays on it is better to have brains than beauty?
No it is not natural beauty only lasts for a brief period of time and once that is gone people turn to artificial beauty which leads to drugs, plastic surgery and illnesses like anorexia. Brains are far better because then you will be able to marry someone who is smart enough to see the beauty inside, you also wont be dumb enough to do drugs or get plastic surgery or stop eating. That is why brains are far better
for me to have brains will always lead the way. why? in our daily live we encounter many people in our life's and the most caughting attention sometime when we walked streets are those beautiful creatures they can even make us turn on because of their physical appearance but that was we see outside ability when you start talking to some of that you will noticed how pooer the conversation will be because majority of those good looking pips were not that smarter though. that's why it is more better to have brains rather than beauty i agree to the first answer when your beauty fades then all who admired you fades but when you are smart and inteligent you may leave this world a legacy which reminds of you even if your already gone that's the point. hehehe
What two components is blood brain barrier made from?
The blood-brain barrier (BBB) is a diffusion barrier, which impedes influx of most compounds from blood to brain. Three cellular elements of the brain microvasculature compose the BBB-endothelial cells, astrocyte end-feet, and pericytes (PCs). Tight junctions (TJs), present between the cerebral endothelial cells, form a diffusion barrier, which selectively excludes most blood-borne substances from entering the brain. Astrocytic end-feet tightly ensheath the vessel wall and appear to be critical for the induction and maintenance of the TJ barrier, but astrocytes are not believed to have a barrier function in the mammalian brain.

The right hemisphere of the brain is in charge of?
The left and right hemispheres of the brain have different functions.
nothing there the same icelin tolliver wrote this
The left brain controls the right side of your body (i.e. being right handed). Characteristics of left brain are using logic, rationality, mathematical, enjoying puzzles, and is focused on written language.
The right brain focuses more on art. Controlling the left side of the body, being left handed. Generally interested in art, creativity, music, thinking outside of the box, etc. :)
Left-brain dominant thinkers abilities and strengths usually are rational analytical, logical, objective thinkers.
Right-brain dominant thinkers tend to be intuitive random and subjective thinkers. They also tend to be the "artsy" type and more creative than left brain people.
the right cerebral hemisphere coordinates left hand control, mathematical ability, spoken language, written language, scientific skills, and logical thinking. the left cerebral hemisphere coordinates right hand control, artistic awareness, three dimensional perception, intuition, imagination, and musical awareness.
What damage will happen if the temporal lobe is damage?
The midbrain is found on top of a structure called the pons. The pons (bridge) is next to the brain stem. The area is very small and the effects of damage depends on where and how much. The best out come is a mild trauma and the worse is cell death that leads to symptoms such as tremors, physical instability and emotional changes. Some think that mental illness may also be the outcome.
TV has become a perverted way to kill the mind. I use to watch TV alot but then i started to see more and more disturbing things on it. I've actually accumulated fears from TV watching. Of corse its not all TV's fault. I personally have come to hate and despise certain acts of things just from watch TV and getting a veiw of how things work in the world on the screen. TV can be entertaining at times but i would say be careful what you watch. If that answers your question. I dont know if you meant what illnesses can occur but I guess if you were to name my illness it would be a phobia of certain things. A discust I could have lived my whole life without wanting to ever know. Well that is what Television does to me. Sheesh, I shound so dramatic. Sorry. Don't mean to be. TV has different effect on different people. Im just a extra sensitive person, I suppose. My thoughts can also hypocrit me while I write a book. Lol
Is the cerebral cortex responsible for reflexes?
Anything involving nerve function is directly linked with the brain, however, reflexes are not the function of the cerebellum. If I remember my brain biology, if I'm not mistaken the lower brain functions are generally the work of the brain stem, or the "reptile" portion of the brain as it was once called in evolution parlance. It was once believed by the theory of evolution that the brain stem evolved first, and then everything slowly "grew" around it within the mammalial species that led to humans, however modern evolutionary biology holds that it came all at once. It has been proven, at least in evolution circles, that reptiles in fact have a cerebellum and brain stem, at least more primitive species that would lead to mammals.
Reflexes I believe are involved with the peripheral nervous system, and that is the work of the brain stem and the hippocampus, in short the "core" of the brain. Movement is the work of the cerebellum, while voluntary action and higher reasoning is the work of the cerebrum, the larger bulk of the brain. All nerve function is directly linked to the brain in one way or other, however, specifically, I believe the part of the brain you are looking for is the brain stem, the "reptile" portion, if the reflexes you are talking about are those involved being struck in the knee by your doctor. If by "reflexes" you mean "reaction time," that is a function of the cerebellum and the brain stem I believe.
How is the cerebellum involved in the control of movement?

What is the function of the reticular activating system?
Part of the mid-brain, it sends impulses to the cerebral cortex to keep it conscious and alert. It is also important for sleep and arousal.
What are the divisions of the brain?
The human brain has three major parts. These parts are the cerebrum, the cerebellum, and the brain stem. Each part has smaller parts.
The brain is the convoluted organ within your cranium (skull). It is the major part of the central nervous system, controlling the functions of the body. It is also the seat of cognitive intelligence. The human brain consists of four major parts: cerebrum, cerebellum, brain stem, and diencephalon.
(the dienchephalon may also be grouped within the brain stem)
What would happen if you didn't have an brain?
Since it controls vital functions such as breathing, swallowing, digestion, eye movement and heartbeat, there can be no life without it. But the rest of the brain is obviously capable of some remarkable feats, with one part able to compensate for deficiencies in another.
You do have a brain everyone does if you don't than you will not live.
first of all it's "Why don't I have a brain?" and scienctificly everyone has a brain even though at times, it might seem they don't.
What phobia is the fear of things on the left side of the body?
Levophobia and Sinistrophobia are names of phobias relating to the fear of objects on the left side of the body or the fear of being left-handed
What part of the brain involves in creativity?
This question really doesn't have a specific answer. Various parts of the brain are responsible for different creative methods. There is a false belief that the different sides of the brain have 2 different functions. While the brain is somewhat lateralized, there is not necessarily a creative 'part'.
Just after puberty, this time is when the brain is 'metaphorically' rushing around trying to sort everything out before you get too old. After this has happened the brain has a hard time trying to learn anything new, as you may know. the brain is constantly developing from birth, this is why babies are able to pick up new languages and abilities so easily compared to everyone else.
Why is damage to the brain permanent?
Damage to these areas can affect thought processing, sensation and/or motor control of the body and so is obviously serious. The reason is is usually permanent is that the neurones do not really get replaces. For the most part, brain and spinal cord nerves do not regenerate. There is new evidence that suggests that they do, but the evidence and consistency of results are not well understood at this point.
The other reason that they seem to be permanent injuries is because one of the nucj=knmaes for the brain and spinal cord is the vital nervous system.
What are the basic differences between the human brain and the animal brain?
Animal brains vary in size, and cannot "think" like human brains can. With the different habits and knowledge, they can not process many human objects. People say that animals' brains are tiny,but some are even smarter than humans!
