Nervous System

an integrated whole, composed of diverse, interacting, specialized structures and subfunctions. [SEMATECH] 2 : an integrated structure of components and subsystems capable of performing, in aggregate, one or more specific functions.

Adenosine receptors stick through the neuron membrane, so that part of them are on the inside and part is on the outside of the cell. Now, when adenosine, a natural chemical in the body, attaches to the adenosine receptor it shifts the shape of the receptor, this shift reaches all the way to the part on the inside of the cell, and causes the receptor to release attached molecules called G-proteins. These g-proteins now float around the inside of the cell and have all sorts of effects, in this case, to inhibit the neuron. Caffeine also binds to the adenosine receptor, but it doesn't activate the receptor. This means that the receptor is totally shut down, and can't work to inhibit the neuron any more. The end effect is to allow the neuron to be more active than it was before the caffeine.

If you think of the brain as a central computer that controls all the functions of your body, then the nervous system is like a network that relays messages back and forth from it to different parts of the body. It does this via the spinal cord, which runs from the brain down through the back and contains threadlike nerves that branch out to every organ and body part. When a message comes into the brain from anywhere in the body, the brain tells the body how to react. For example, if you accidentally touch a hot stove, the nerves in your skin shoot a message of pain to your brain. The brain then sends a message back telling the muscles in your hand to pull away. Luckily, this neurological relay race takes a lot less time than it just took to read about it!

Yes, it is possible for a person to be unconscious and still exhibit involuntary reflexes such as coughing or facial movements. These reflexes are controlled by the autonomic nervous system and do not require conscious input from the brain.

ventral root from the ventral horn of the spinal cord is motor. If ventral root is cut it will lead to to a kind of paralysis called flaccid paralysis. This is because ventral horn contains lower motor neurons. As such the skeletal muscle innervated by the root is paralysed

The nervous system consists of the brain, spinal cord, sensory organs, and all of the nerves that connect these organs with the rest of the body.

Together, these organs are responsible for the control of the body and communication among its parts.

An illusion is a distortion of the senses, which can reveal how the human brain normally organizes and interprets sensory stimulation. Although illusions distort our perception of reality.

The effects of illusion on the central nervous system makes you think that you are seeing things -- such as a curved line that's actually straight, or a moving object that's standing still. You wonder if your eyes are playing tricks on you.

It's not your eyes. An illusion is proof that you don't always see what you think you do -- because of the way your brain and your central nervous system perceive and interpret things.

Illusions occur due to properties of the visual areas of the brain as they receive and process information. In other words, your perception of an illusion has more to do with how your brain works -- and less to do with the your eye.

An illusion is a mismatch between the immediate visual impression and the actual properties of the object.

Everything that enters the senses needs to be interpreted through the brain -- and these interpretations occasionally go wrong.

An illusion is a phenomenon in which our subjective perception doesn't match the physical reality of the world.

An example of the effect of illusion on the central nervous system is when you "see stars" after a hard blow to the head.

Seeing stars results from a mechanical stimulation and activation of the neurons in the eye, which your brain misinterprets as light. Light does not enter the eye when you hit your head, but your visual system perceives it that way.

Another examples of the effect of illusion on the central nervous system happens to the Pilots who always encounter visual illusions while in flight, such as a false horizon, or when landing, such as a narrow runway.

But due to their training, they are able to recognize and ignore these illusions so they can safely fly their aircraft.

But while some effects of illusion on the central nervous system may pose a safety threat, others may actually be used as safety measures.

On Chicago's Lake Shore Drive, for example, the effects of illusion on the central nervous system have been used to control drivers' speed on a hazardous curve.

Stripes on the road are painted closer together as drivers approach the sharpest part of the curve. The illusion makes drivers think they're speeding up -- so they tend to slow down naturally.

The effect of illusion on the central nervous system can offer scientists new insights on how vision and the brain work -- and are more than intriguing parlor tricks.

They widen the mental horizons and make it clear that things are a little different than they seem.

The effects of illusion on the central nervous system are not just some nice puzzle, like a crossword for example, they are important tools in visual research to help us understand how visual processing works in the normal brain and also in the diseased brain.

Beyond their amusement value, the effects of illusion on the central nervous system may also serve an evolutionary purpose.

The brain is always constructing things, which is helping you survive. Some of these constructions can be fiction.

Effects of illusion on the central nervous system makes the brain attempts to perceive the future, and those perceptions don't match reality, which tends to cause delay for the brain to reprocess and act accordingly or lead to an accident which at times could be life threatening or minor

The brain is a limited structure, with limited resources, including its number of neurons, wires, and neuronal connections, So in some cases, the effects of illusion on the central nervous system tends to make the brain need to take shortcuts, which makes the brain tend to quickly give more importance to some features in a visual scene than others.

The effects of illusion on the central nervous system can not be over emphasized, but we adopt and live with them as they have become part of our everyday life.

Like any other system, when there is no power supply it turns off, such as you have a car and the driver is gone, car doesnt work by itself, so the Life Force (your spirit) no longer fits to this body, because the body damaged or too old to cope with the spirit energy.

The cerebellum, located at the back of the brain, is responsible for coordinating motor activities and helping to maintain balance. It receives information from the sensory systems, spinal cord, and other parts of the brain to regulate voluntary movements and posture.

countries that are not developed.

The action when you close a window because you notice rain is falling is called a response.

Broad question and answer...of course the general health of the system as well as local things like drugs and alcohol, but also so-called spiritual or metaphysical triggers can affect the performance. There is much study going on now, but science is still in grade school on the broader ideas. A positive outlook in all areas of life sciences aids discovery. Prayer is efficacious.

No, not at all. The myelin sheaths are actually made by other living cells in the nervous system known as glia. Two types of glia myelinate the nervous system: oligodendrocytes and Schwann cells. The oligodendrocytes for myelin in the central nervous system (brain and spinal cord) and the Schwann cells form myelin in the peripheral nervous system (everything outside the brain and spinal cord).

The "AMERICANS WITH DISABILITIES ACT" or A.D.A. protects a person's employment due to any disability, including mental illness that causes the person to need to take time off, and be "reasonably accommodated".

The onus is on the employee, however, to inform the employer that they have a mental illness or disability that they need accommodations for. They do not, however, have to inform them during the interview process before they are hired.

If you suffer a mental illness that happens after you are employed, your employer is required to work WITH you to accommodate your issues.

(reduce your work load, work hours, give you different tasks to do that are not as stressful, etc)

There are exceptions to this law, but this is a quick synopsis of it. The answer in essence is NO, you SHOULD not lose your job if you have a nervous break down, and if you DO, then you have options for getting it back, as well as a potential lawsuit!

This sensation is called deja vu. When you experience deja vu, you feel as though you've had this experience or done this thing before.

Nerve impulses are transmitted from the receptor to the central nervous system via sensory neurons. In the central nervous system, the impulse is processed and may be relayed to motor neurons that carry the impulse to effectors such as muscles or glands to produce a response. This pathway allows for communication and coordination between different parts of the body.

somebody please answer this question.. I've been searching in the net for the answer and nothing popped out. I can't start writing my homework since this is the first one. please help me:))

This behavior is recognized as impulsivity, where a person acts without thinking about the consequences of their actions. It can be a symptom of various psychological disorders, such as ADHD, bipolar disorder, or borderline personality disorder. Treatment may involve therapy, medication, and developing coping strategies to improve impulse control.

The central nervous system, which consists of the brain and spinal cord, coordinates incoming sensory information and sends instructions to muscles and glands. This information processing allows for both voluntary and involuntary responses to stimuli.

The nervous system is referred to as a communication system because it enables the transmission of signals between different parts of the body. It uses electrical impulses and neurotransmitters to relay information quickly and efficiently, allowing for coordination of bodily functions and responses to external stimuli.

The motor neurons of the peripheral nervous system send signals from the central nervous system to the muscles, causing them to contract and move. These signals are transmitted through neurotransmitters released at the neuromuscular junction.

The hypothalamus is not directly responsible for consciousness. It plays a key role in regulating basic survival functions like hunger, thirst, body temperature, and hormone release. Consciousness is a complex phenomenon influenced by widespread brain activity involving various regions like the cortex and thalamus.

There are many factors connected to physiological aspects of behavior. The environment, preexisting conditions, and internal stimuli. Each of these may impact behavior independently or collectively.

Stupid Noobs PHYSICAL NEEDS is food shelter, etc.

But the question is "Can you give me and example of physiological needs?"

and yes, I can.

Physiological Needs are stuff that bring you happiness for example:

Religion, Etc. Etc. Or... NeverMind

The neuron is the smallest functional unit of the nervous system. It is responsible for transmitting information through electrical and chemical signals. Neurons make up the basic building blocks of the nervous system and are essential for communication within the brain and between the brain and the rest of the body.
