Brain

For Special Scientest, Denzel its Blue!

What is are the other major subdivisions of the brain? What is are the other major subdivisions of the brain?

The medulla oblongata controls heart rate and respiration.
Controlling essential body functions like heartbeat and breathing.

it contains specialized nephrons

ventricles, cerebellum,cavum ceptum pellucidum, choroid plexus.

The cerebrum is largely responsible for interpreting your sensations (sight, hearing, touch, etc) and moving your muscles. It also is the seat of consciousness and where your personality arises from.

There are many to list, but any drug that works on the Central Nervous System (CNS) will effect the brain. Because there are many drugs that fall into that category, I will list the top few that come to mind....those used to treat major psychiatric disorders such as thought disorders, affective disorders and anxiety disorders. First, the thought disorders, such as schizophrenia, dementia and delirium. Aricept (donepezil) is a cholinesterase inhibitor used to treat Alzheimers disease, and its mode of action is to enhance acetylcholine by blocking the enzymes that break it down. Antipsychotics such as Haldol (haloperidol), Zyprexa (olanzapine), Seroquel (quetiapine), and Risperdal (risperidone) work by decreasing Domamine levels. If you look at affective disorders (depression and bipolar), you will find the SSRI's --Celexa (citalopram), Cymbalta (duloxetine), Prozac (fluoxetine), and Zoloft (sertraline). These work by enhancing neurotransmitter (specifically seratonin). Mood Stablizers such as Lithium, Depakote (valproate) and Tegretol (carbamazepine) all act to slow neuronal transmissions. Finally, the anti-anxiety meds (anxiolytics). Meds such as benzodiazepams -- Xanax (alprozolam), Klonapin (clonazepam), and Ativan (lorazepam) -- work to enhance GABA, which calms people down.

The reptilian brain contains the cerebellum and brain stem. It is present in reptiles and therefore called the reptilian brain. It is the oldest part of the brain and regulates vital functions like breathing, heart rate and flight or fight response.

medulla,cerebellum,and cerebrum by mike k.

The hindbrain includes the cerebellum , the pons and the medulla oblongata , which function collectively to support vital bodily processes.

The medulla is joined to the spinal cord and controls unconscious, yet essential, body functions such as breathing, swallowing, blood circulation and muscle tone. Located above the medulla is the pons which serves as a bridge to connect the brainstem and the cerebellum. The pons receives information from visual areas to control eye and body movements and also plays a role in controlling patterns of sleep and arousal. Information is relayed from the pons to the cerebellum to control the co-ordination of muscular movements and maintain equilibrium.

The brainstem is made up of the pons, medulla and midbrain . The medulla connects the brain to the spinal cord and its motor and sensory tracts allow communication between the brain and the rest of the body.

No a person can not live without a brain. You can not live without a brain because it controls everything. Although, some functions of the body are automatic, and a person can live if the brain stem is intact.

Yes, they both make up the central nervous system. Nerves from the brain stretch right down to the tip of the spinal cord. The connection between the spinal cord and the brain is required for almost all movement/sensation in the body, from the neck down.

The medulla oblongata is most vital part of the brain bcoz it controls the respiratory system . the medulla oblongata regulates involuntary functions, or those that are not under our control such as breathing and heart rate.

The term brain drain refers to the loss of educated people to another country. You can stop by my having jobs that fit their skills and pay them well.

The folds, or sulci, of the cerebrum allows the cerebral cortex to have more surface area and therefore more brain cells, or neurons, that make up the brains mass. Cognitive function seems to be related to the surface area of the cerebrum. Convolutions increase the surface area. Animals with less convoluted cerebra have lower intelligence than those with more. As an example, 'possum brains are nearly smooth.

pain reach our brain by the nerves i think so .

Sleeping and waking depend on activities in the brain stem. Several areas of the brain seem to be involved in dreams and REM sleep, including the hippocamus and cortex. See attached links.

yes, it is said that it creates holes in your brain.

If a person has no brain activity in their brain, then that person may be considered brain dead. Brain dead is a legal indicator of death in some states. without brain activity, a person most likely will be unable to keep their body functioning without some form of life support, their major organs would start to fail.

There has been cases of a babies born with just a brain stem. They need to take medications to survive, such as seizure meds. Nicolas Coke I believe lived to be 2 years old but I am unsure if he is still alive.

Moderate diffuse cerebral volume loss means the brain has shrunk in size. This result is determined by a doctor after an MRI has been performed on the patient.

Speed of light is a lot faster than the electro-biochemical events that our brain runs on.

the right cerebral cortex

The most important one is the brain. A surgeon can do surgery on the brain while the patient is awake.
