What increases the surface area of the brain?
The convolutions in the brain increase surface area. In simpler words, those lines and ridges in the brain are what increases the surface area.
No. Oysters do not have a central nervous system. There are only a few ganglia to control impulses.
What is the medulla oblengata responsible for?
do ur home work by paying attention in class dont search it here
What is the difference between right-brain activities and left-brain activities?
The idea that we have a dominant brain hemisphere has been generally discredited, mostly because it is not even scientifically true. The the thought that left brainers are logical, good with mathematics and language, while right brainers are creative and artistic has no basis in fact but has captured the imagination go the same groups that believe in other pseudoscience babble.
What is the function of medula?
the function of the medulla is that controls breathing, heart function, blood vessel function, digestion, sneezing and swallowing.
Why is there a front and back on a brain?
The back part of the brain processes our raw senses. The back part of the brain takes these raw senses and performs association and analysis.
What are the parts of the nervous system and its function?
The function of the nervous system is to enable us to feel our surroundings. The five senses (sight, touch, hearing, taste and smell) have different sensory neurones in various parts of the body. The most sensitive parts of the body are the fingertips and lips, which have far more sensory neurones per square centimetre than other parts of the body. The nerve impulse travels from the sensory neurone, across a synapse (the gap between the end of one neurone and the dendrites (fingers) of the next) and reaches the next neurone. The signal reaches the coordinator (either the brain or spinal cord) and is then sent to a certain part of the body via a motor neurone, which eventually reaches the muscle and causes a movement. The nervous system is effected by stimulants and depressants, such as alcohol and drugs, which change the speed of reaction times.
Does alcohol give you brain damage?
Small quantities of alcohol are thought to be good for you. However, if you exceed the recommended daily and or weekly amounts, alcohol is harmful to the body. Taken in excess there is evidence that it damages the liver and perhaps the brain.
How does math affect the brain?
It affects the brain by applying knowledge and getting some of the unorganized matter back in function. It affects the brain by applying knowledge and getting some of the unorganized matter back in function.
What are the four sections of the brain?
The general areas of the brain are the cerebrum, cerebellum, the brainstem, and the area of the thalamus and hypothalamus, sometimes called the diencephalon.
*The medulla oblongata, the lower part of the brainstem, may often be listed separately, with the thalamus and hypothalamus grouped with the brainstem, as they are between the cerebrum and the brainstem.
(The four lobes of the cerebral cortex are the frontal, occipital, parietal and temporal.)

Another possible division of the brain is into these parts.
The cerebrum is the largest part of the brain and is associated with higher brain functions like thought and action.
The cerebellum is associated with regulation and coordinates movement, balance and posture.
The limbic system, which is found buried within the cerebrum.
The brainstem, which is responsible for basic vital life functions such as breathing, heartbreat, and blood pressure.
Why do people feel scared or threatened by people who are different?
it could possiby be that that person is just paranoid or that they feel threatened around some one diff. or they are afraid of diffrences.
Depends on the place of shot. # On the stomach it will take a few minutes. The acid from the stomach will eat away at al your internal organs. The longest time ever to live after being shot in the stomach was 23 minutes. # In the heart there is instant death, but your muscles keep working by muscle memory. # Leg, Hand, Arm, Foot. Might now be able to walk or pick up any thing.
The brain stem is about the size of a thumb in diameter and approximately 3 inches (approximately 7.5 cm) long. It structures are the midbrain, pons, and the medulla obongata. The midbrain is mostly composed of tracts of nerve fibers. The midbrain has two bulging fiber tract-cerebral peduncles. It also has four rounded protrusions. The midbrain reflex centers for vision and hearing. The pons are the bulging center part of the brain stem. It is mostly composed of fiber tracts. It includes nuclei involved in the control of breathing. The medulla oblongata is the lowest part of the brain stem, it merges into the spinal cord, includes important fiber tracts, and contains important control centers. Heart rate control, blood pressure regulation, breathing, swallowing and vomiting. Recticular formation, diffus mass of gray matter along the brain stem. Involved in motor control of visceral organs. Reticular activating system plays a role in awake/ sleep cycles and consciousness
Why do men like women that don't like them and don't like the women that likes them?
That's life and there's little we can do about it. Just try to avoid these kinds of situations and you will be happier in life.
It could be that nature made men to be hunters. If something runs, a hunter chases after it. They may enjoy the thrill of the hunt. If they can have certain women at any time, they might not see any fun in that. There is no challenge nor the chance to prove their masculinity? So a mistake that women may make is making themselves too available when outside a relationship, and doing too much for the man within a relationship.
What is the function of the brain stem?
The function is to regulate the flow of information between the brain and the rest of the body.

What is the brain protected by?
The brain is protected by a series of bone, membrane, and fluid. The outermost protection is the cranium, or skull, which protects the brain from blows that could easily damage it. Then there are three membranes called meninges. The first of the three, dura mater, lines the inside of the cranium. The thinner arachnoid membrane lies just beneath this. Finally, there is the pia mater that covers the brain directly. Cerebrospinal fluid(CSF), Liquor cerebrospinalis, is a clear bodily fluid that occupies the subarachnoid space and the ventricular system around and inside the brain. Essentially, the brain "floats" in it. More specifically, the CSF occupies the space between the arachnoid mater (the middle layer of the brain cover, meninges) and the pia mater (the layer of the meninges closest to the brain). It constitutes the content of all intra-cerebral (inside the brain, cerebrum) ventricles, cisterns and sulci (singular sulcus), as well as the central canal of the spinal cord. It acts as a "cushion" or buffer for the cortex, providing a basic mechanical and immunological protection to the brain inside the skull.
It's called Xenoglossy. Professor Ian Stevenson has done some very interesting research over the years to determine whether this and other related phenomenon could be used as evidence for existence of Reincarnation.
Are cooling system problems common on the 97 Suzuki sidekick?
no.
not common at all.
is car too hot , too cool
does top radiator hose get too hot to touch, Normal.
