The lower pons is a region located in the brainstem, which is responsible for relaying sensory and motor information between the cerebrum and the medulla oblongata. It also plays a vital role in controlling certain functions such as facial expressions, sleep, and consciousness.
old age affects memory because as you grow older you become more weak and feeble, the circulatory system starts to work slower and cant pump enough blood to the brain for it to work better. young age (Like babys) affects memory because they havent had enough neurons to enter their brain yet, also, they don't challenge their brain and are barely learning to do things
What is acute congestion of brain and stomach?
scarlet fever, poor man's disease or doctor phone option's(phone pictures sent for second option)
Researchers would be most likely to make use of fMRI (functional magnetic resonance imaging) to study brain activity while people recall familiar nursery rhymes. Specific brain areas that might be most active during this task include the language processing centers in the left hemisphere of the brain, such as the Broca's area and Wernicke's area.
What is the medical term meaning inherited autoimmune disorder characterized by gluten intolerance?
The medical term is "celiac disease." It is an inherited autoimmune disorder where the immune system reacts to gluten, a protein found in wheat, barley, and rye, causing damage to the lining of the small intestine. This can lead to digestive issues and malabsorption of nutrients.
What is the medical term meaning inflammation of the cerebellum?
The medical term for inflammation of the cerebellum is cerebellitis. It can be caused by various factors such as viral infections, autoimmune diseases, or bacterial infections. Symptoms may include dizziness, loss of coordination, and headaches.
What does the brain teaser deci sion mean?
The phrase "brain teaser decision" is unclear without context. It could refer to a decision-making challenge designed to be mentally stimulating, often in the form of a puzzle or problem. More details would be needed for a precise interpretation.
What connects the third and fourth ventricle f the brain?
The cerebral aqueduct connects the third and fourth ventricles in the brain.
Which animals brain is smaller than its nose?
Not entirelly sure though i do know that an osterichs eye is bigger than its's brain i feel sorry for it :(
When does a baby have normal brain waves?
Generally speaking, the first measurable brain waves can be captured on an electroencephalogram (EEG) around the 12th week of pregnancy.
Prior to that, the central nervous system of an embryo begins to develop in a sequence from "tail" to head. The brain tissue and the creation of a spinal cord are some of the early structures that begin the development process of the nervous system, but it will be longer before they are fully functioning.
In the fifth week after conception the first synapses begin forming in an embryo's spinal cord. Conception is traditionally defined as when the egg and sperm unite to form a new human being, initially called a zygote, however several years ago the American Association of Obstetrics and Gynecology decided to change the definition to a week later when the embryo implants in the uterus. To add to the confusion, obstetricians typically date pregnancy from about 3 weeks earlier at the time of the last menstrual period. Thus, it is very important to know what definitions are being used when studying prenatal (before birth) human development. Synapses are what connections of nerves are called. By the seventh week after the embryo begins development, these early neural connections permit the first movements of an embryo. The woman will not feel these movements but researchers can detect the movement through ultrasound imaging. These first movements do not involve fine motor movement but are trunk movements caused by the muscle and central nervous system development.
Other movements will follow--of the limbs (around eight weeks) and fingers (ten weeks), as well as some reflex movements such as hiccuping, stretching, yawning, sucking, swallowing, grasping, and thumb-sucking. By the end of the first trimester (first 3 months), a fetus's movement repertoire is remarkably rich, even though most pregnant women still feel none of it. Many women sense or feel the first fetal movements in the 5th and 6th months of the pregnancy; some may feel something as early as eighteen weeks of pregnancy.
Terminology:
A zygote is the first step in development of an embryo. The zygote formed from the union of 2 haploid cells (sperm and egg) to form one diploid cell. It is the first stage of the embryo. As the embryo is transported don the Fallopian tube to the uterus, further development occurs. At about one week, the blastocyst (name for that stage of embryonic development) implants in the uterine wall. 8 weeks after fertilization, when all organ systems have formed, the embryo is called a fetus up until birth, and then for the first 28 days after birth the medical term is neonate. These are the proper medical terms, but in English the term "baby" or "child" is used from the day the zygote is formed until a year - or several years - after birth. "Infant" can also be used for the first year after birth.
How big is an average chicken?
== == There are approximately 175 varieties of chickens grouped into 12 classes and approximately 60 breeds. That makes defining the "average chicken" very difficult.
The majority of chickens in North America are raised for either meat or eggs, in market terms, a broiler or fryer is a young meat chicken that can be cooked tender by broiling or frying and usually weighs in between 2 1/2 and 3 1/2 pounds.
A roaster is a young meat-type chicken that can be cooked tender by roasting and usually weighing 4 pounds or more.
A stewing chicken, hen, or fowl is a mature female chicken, often the by-product of egg production, are about 5 pounds plus.
This question does have an answer, though I won't give unless you come back stumped. You walk into a bank. You give the teller a check for $63.00. She will give you back 8 bills, what are they? Note. There are NO one Dollar bills in the change she will give you, and no change as dimes nickels quarters. The 8 bills she will give you will be higher than a $1.00 bill.
I know the answer to this you can use a $5.00 bill, a $2.00 dollar bill, and 100 pennies becasue you only said tht you couldn't use dimes, nickels, or quarters. And plz write bck to tell me if im write, or not, or close. THNX
What are the positives of having two brains?
Some good things about having two brains:
- You can concentrate on doing 2 things at the same time.
- You can donate 1 for someone in need.
- If one of the brains gets damaged, you still have another one.
- You could be twice as smart, depending on whether you can get the brains to work together.
- Each brain could work with one ear, so you could concentrate on two conversations at the same time. (And talk to both of them too. Wow that would be a total mess. imagine each person talking to more than 1 person at the same moment!)
- You could sleep with one and let the other finish your homework at the same time.
- You could have great conversations with yourself.
- Someone would always understand your perspective.
What can a brain do a computer can not do?
Through years people have compared the brain to different inventions. In the past, the brain has been said to be like a water clock and a telephone. These days, the favorite invention that the brain is compared to is a computer. Some people use this comparison to say that the computer is better than the brain; some people say that the comparison shows that the brain is better than the computer. Perhaps, it is best to say that the brain is better at doing some jobs and the computer is better at doing other jobs.
Both use electrical signals to send messages the computer uses wires to carry messages and the Brain uses motor neurons. Both can do math and other logical tasks. The computer is faster at doing logical things and computations. However, the brain is better at interpreting the outside world and coming up with new ideas. Both need energy, the brain needs nutrients like oxygen and sugar for power; the computer needs electricity to keep working. Both can be damaged It is easier to fix a computer but there are no new or used parts for the brain Both a computer and a brain can get "sick" - a computer can get a virus and there are many diseases that affect the brain. The brain has built-in backup systems in some cases. If one pathway in the brain is damaged, there is often another pathway that will take over this function of the damaged pathway.
What is the difference between a microprocessor and human brain?
Both a human brain and a CPU perform computations.
A CPU is basically a serial device (a Von Neumann machine). Its computation steps are discrete. Its operations are chosen from a small set. It does some things, like arithmetic, extremely well. It never gets tired. It uses lots of energy. It interfaces with external devices (memory, ALU, Input and Output).
A human brain is a parallel interconnected device. Its computation steps are continuous. It has a large set of operations. It does some things, like face recognition, extremely well. It often gets tired. It is much more efficient energetically than a CPU. It interfaces with external devices (eyes, ears, nose, mouth, skin).
This is not even scratching the surface - Go read, say, "Goedel, Escher, Bach" in order to get a feel for how large this question is.
Is it safe to bungee jump after brain surgery?
Its fine!! As long as you dont have sex before bungee jumping!
Why are women braver then men?
women tend to rely more on emotions. For decision making, while men think logically.
The brain controls the human body.
I don't know if the answer above is supposed to be sarcastic, or just someone who doesn't know and wanted to add something anyway. That is an incredibly useless answer.
In part, the brain controls movement of all body parts, temperature, heart beat, interprets feeling and pain, breathing, when you sleep it regulates breathing and controls the heart, and does much more, but since I'm not a doctor, that is about all I know.
Does the brain control hunger?
The hypothalamus influences food intake, weight regulation, fluid intake and balance, thirst, body heat, and the sleepcycle.
Is reflex action and reflex arcs are same?
Reflexes are uncontrollable movements that happen almost instantly in response to a stimuli. A reflex arc, a neuronal circuit that controls reflexes, is where reflex activities takes place.
What is the cerebellums function?
The cerebellum is the motor movements center of the brain, governing posture, coordination, balance, speech, etc.
Why is the brain convoluted in appearance?
It's wrinkled convoluted appearance is due to a growth spurt during the fourth and fifth months of embryonic development, when the gray matter of the cortex is expanding greatly as it's cells grow in size. The supporting white matter, meanwhile, grows less rapidly; As a result the brain takes on the dense folds and fissures characteristic of an object with great surface area crowded into a small space.
