Nervous System

This category is for questions about the mechanical and chemical process of reactions to internal and external stimuli, ranging from the brain down to the spinal cord, and all nerves, cells and tissues in between.


Thank you for your question. My answer is "No." However, an injury to the cervical spinal nerves or those evenlower, like an injury to the axillary (armpit) nerves or those inthe elbow region can cause the symptoms of a pinched nerve withpain in the wrist. Pain would be located at the nerve injury...
Vicodin has the potential to alter the brain's neurotransmitters.
If the disc is properly positioned then no the peripheral nerveswill not be inhibited in any way. However if the disc is improperlypositioned then it will put pressure on the nerves causing them tobecome impaired.
The internal tendon bulk is thought to contain no nerve fibres, butthe epitenon and paratenon contain nerve endings, while Golgi tendon organs are present at the junction between tendon and muscle.

In fact, a girl's brain does not weight more than a boy's brain. The average Male's brain weighs 1360 grams (3 pounds) The average Female's brain weighs 1250 grams (2.8 pounds) Of course, brain weight does not really mean anything, and is certainly not associated with intelligence. To...
The 3 major divisions of the brain are: C erebrum - fills up most of your skull. It is involved in remembering, problem solving, thinking, and feeling. It also controls movement. Cerebellum - sits at the back of your head, under the cerebrum. It controls coordination and balance. Brain...
The pituitary gland is often called that as it controls all of the other glands but i have never heard it said of the hypothalamus
The nervous system is connected to many systems and organsincluding, the skeletal system and the cardiovascular system. It isimportant to protect your nervous system to have a healthy life.
They don't, the neurotransmitters stay on either side of thesynapse. Neurotransmitters are released when the synaptic vesiclesfuse with the presynaptic neuron's membrane, so as to release theminto the synaptic cleft.
The condition where you need a shunt because of abnormal build upof cerebrospinal fluid on the brain is called hydrocephalus (orcommonly water on the brain).
The brain without it you wouldn't really have beauty you would bementally impared
Go to the vet. . Prognosis depends on the severity of the damage. See here for further info: .
Myelin sheath , comprised of glial cells wrapped around an axon one after another (oligodendrocytes in the CNS, schwann cells in the PNS).
The dura mater is the outermost membrane of the brain and spinal cord. The dura mater is is responsible for keeping in the cerebrospinal fluid.
Hagfish, Lobsters and Crabs. As well as Mantis Shrimp.
Actually it is the same. It depends on person to person so youcan't differentiate between the two. It all depends on the chemoreceptors and the response of the synapses.
Tourettes Syndrom is a condition in the Nervous System
Yes, endorphins are brain chemicals known as neurotransmitters.They transmit electrical signals within the nervous system.
It really all depends on what the brain damage was. Someone mighthave had a stroke, a traumatic brain injury, a tumor, bleeding inthe brain, or many different things.
You have paresis of the muscles. You have rigidity or increasedtone. You have exaggerated reflexes.
Experience creates new networks of neurons in the brain.
Glia. Its a glue that connects one neuron to another.
The cell body is part of the neuron, so it could be consideredthat.
They are called as interconnecting or intermediate neurons.
This video by overviews the top ten spinal cord injury rehabilitation centers in the United States. The website also has much information on brain and spinal cord injuries.
You can protect it by if hurt putting a brace around it. But there are many other ways.
Not really. Both hemispheres contribute to both kinds of processesand experimental evidence provides little support for correlatingthe structural differences between the sides.
The axon of some neurons can be a long, thin structure, wrapped by a myelin sheath to help it convey an impulse quickly over long distances and retain its strength (saltatory conduction).

Adenosine receptors stick through the neuron membrane, so that partof them are on the inside and part is on the outside of the cell.Now, when adenosine, a natural chemical in the body, attaches tothe adenosine receptor it shifts the shape of the receptor, thisshift reaches all the way to the part on...
There are certain types of advertising, first is print media includes, newspaper, magazine, yellow pages, direct mail. Another way of advertising is electronic media including every means of advertising apply with electronics including internet, tv, radio, telegraph. Now ur question that...
There is a hole in the middle of each vertebrae called a foramen. So the spinal cord passes through the vertibral foramen.
You have heard it said that we only use 10% of our brain. That isuntrue, we use 100%.
The medulla oblongata is a portion of the hindbrain that controlsautonomic functions such as breathing, digestion, heart and bloodvessel function, swallowing and sneezing.
Probably but not necessarily. You could survive this trauma with any of a wide spectrum of brain damage, and any of an accompanying range of severe mental and physical impairments.
No. Snot is phlegm.
The central nervous system to be specific, but its definitely part of your body.
The pons is a portion of the brain located above the medullaoblongata and the midbrain. It is a message station between severalareas of the brain.
yall suppose to know the answer yeah i ain't gonna tell yall.....dhat
One is west nile virus, caused by mosquitoes. There are more than a dozen viruses that can cause encephalitis, spread by either human-to human contact or by animal bites. Encephalitis may occur with several common viral infections of childhood. Viruses and viral diseases that may cause encephalitis...
Insufficient levels of dopamine can cause problems with sleep, moodand movement. For example, lack of dopamine causes the muscularproblems seen in people with Parkinson's disease.
The brain stem is necessary to control all involuntary functions inthe human body. Signals are sent up and down the brain stem thattell your heart to beat and your lungs to breathe.
Hyperpolarization means that the membrane potential becames more negative than the resting potential. This means that it is more difficult for an action potential to be triggered at the postsynaptic membrane. This occurs at inhibitory synapses. Hyperpolarization can be achieved by increasing the...
The brain works in many ways. One way it works is because we sleep, in which "charges our batteries" and another is learning, watching and seeing things. the brain also works by sending electrical impulses , for example when we see things it is because light hits our retina in the back of the eye...
Answer . Reflexsive behavior in infants is not too unlike instinct in an animal. Reflxsive behavior could include grasping, sucking, and leg flailing (walking) THese are the servival skills every healthy baby is born with. Grasping, in order keep from falling, stay close to the mom..., sucking...
To acquire an actual study sample, you would probably have to settle for an animal brain, and even those are restricted due to animal rights considerations. Chickens, frogs, lizards, and other simpler animals present no such restrictions, and the cost is mainly due to the chemical preservatives used...
Well, the evolution of a complex nervous system makes it possible for "various animal species" to have advanced perception abilities like sight, smell, hearing, touch, and taste.
The spinal cord stretches from the brain stem to the base of thespinal column. Its job is to convey messages to and from the bodyto the brain.
Impulses that travel along myelinated neurons are the fastest.
.. is a very diffuse topic.

Brains are accually grey, not pink, despite what most people think
A stroke or brain aneurysm canresult in sudden blockage of blood flow the brain, which can resultin disability or death. Other conditions, such as central nervoussystem vasculitis can also cause similar symptoms. .
yes the vertebrates have a brain because humans are vertebrates and we have brans
the somatic nervous system is also known as the voluntary nervous system it is a part of the peripheral nervous system
Information entering the central nervous system from the externalenvironment is called external stimuli. External stimuli arefactors which are detected by the body and communicated to thecentral nervous system such as temperature and scents.
The brain and spinal cord are considered the Central Nervous System. All other nerves that connect to them are part of the Peripheral Nervous System .
Well, your brain is divided into 2 parts. The left side is for language and logic- such as math, reading, history, spanish, you get the point. The Right side is for creativity such as art, and music. Why it's divided into 2 parts, I am not sure. maybe so you can think about more at once because each...
The parietal lobe is a part of the cerebrum. It is responsible for accepting the sensations from the body and in holding and using objects. Also for interpreting the relationship of space and our bodies (like for grasping an object or picking one up or using tools like forks to pick up food and get...
yes hairspray does kill brain sells
Yes, it can change it in many ways. Especially things that are easily affected such as the pitch of your voice. Have you ever blown up a balloon and then squeezed the end between your thumb and first ringer with both hands and pulled tight, letting the air out slowly to hear a strange sound? Well...
While the activation aspects of PTSD (rage, anger, irritability,somatic re-activations) have alot to do with a hyperarousal of thesympathetic nervous system that runs through the right side of thebrain, PTSD from a brainwave side of things has more to do withdisharmony and imbalance between the left...
The average (median) reaction time is 215 milliseconds.
