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.

White matter of the nervous system is composed of?
White matter in the nervous system is caused when the axons in the area are myelinated. This means that the axons have a fatty protein covering to provide insulation. The myelin sheath is composed of special cells calls Schwann Cells.
One function of the nervous system is to send information to and from all parts of the body?
duhhh the nervous system
Is monkeys central nervous system different from humans?
Monkeys Brains are about 400g were as human brains are about 1400g and are 15cm, monkeys brains are only about 8cm long!
The different ways of taking care of the nervous system?
Tips on how to take care of the nervous system:
1. To protect the brain, avoid any fall or accident that can injure it. Observe safety measures to avoid falls and accidents.
2. Eat foods for the brain and the nerves. These foods are those rich in Vitamin B like beans, peas, mongo, and vegetables.
3. Coffee, tobacco, and alcoholic drinks are not good for the nervous system. Medicines and drugs should be taken only with a doctor's prescription or advice.
4. Learn the art of relaxing your mind, nerves, and senses. Use your leisure time wisely.
remember: VITAMIN B!! not vitamin D. :)
What is another name for the visceral motor nervous system?
Another name for the autonomic nervous system (ANS) is the visceral nervous system.
& u can also called it vegetal nervous system....
What are the cranial nerves belonging to senses?
Sensory nerves are the nerves that allow people to experience taste, touch, smell, sight, and hearing. For sight, there are photoreceptors; for hearing, there is stereocilia; for touch, there are motor neurons, and for smell there are olfactory sensory nerves.
The actual site of information processing in the nervous system is the?
To date, no credible answer has been found to this question. There is no apparent single location in the brain where the huge amount of information coming from body and discrete areas of brain are integrated. Though much is known about the function of different parts of the brain, and the blueprint is the same for every human being under the sun, the way that it is all put together to achieve consciousness of different stimuli simultaneously is not understood. This is one of the central puzzles of modern neuroscience, and a hot area of research.
How do central nervous system depressants work?
Most CNS depressants activate a neurotransmitter called gamma-aminobutyric acid (GABA), which helps decrease brain activity.
Sensory nerves are part of the peripheral nervous system which includes the cranial and spinal nerves. They bring impulses to the central nervous system which includes the brain and spinal cord. Peripheral means the sides and that is why the sensory nerves are referred to as the peripheral nervous system.
All of the nervous system is related to the skin because both the nervous system tissues and skin tissues originated in endoderm during the gastrula stage of embryonic development.
The sensory nerves form the link between receptors and the central nervous system (CNS). They carry nerve impulses from stimulated receptors to the CNS. They are also referred to as afferent nerves.
Can nervous system be represented in a flow chart or an expandable tree structure?
Expandable tree structure indicating the hierachical nature of the nervous system
What are tiny pulses of electricity that move along a nerve fiber?
Nerve signals
Thats what my crossword was.
What weighs about 3 pounds feels like soft butter and is the command center of your body?
The brain weighs about 3 pounds, feels like soft butter, and is the command center of your body.
What part of the nervous system is responsible for the rest and digest response of the body?
Parasympathetic
What statements are correct in regard to the nervous system?
The brain and spinal cord make up the CNS (central nervous system).
Which nerves carry sound impulses from the inner ear of the brain?
The auditory nerve carries auditory impulses to the brain.
What advantage does the nervous system have over the endocrine system?
The messages of the nervous system are relayed by nervous impulses, which are very fast and short-acting. In contrast, the messages of the endocrine system are sent via chemical messengers (hormones) distributed by the circulatory system. This distribution in your blood is much slower than the electrical impulses of the nervous system.
What are the 2 main parts of the nervous system and what do they do?
The peripheral and central nervous systems (PNS and CNS) are the two major branches of the nervous system.
The CNS is where the most sophisticated processing occurs. It is where information from all senses are integrated in time; where memories are formed and recalled; where movement commands are planned and sent to lower motor neurons; where emotion is regulated; where mental thoughts originate; and where your personality comes from.
The PNS system acts as a 'mediator' between the body and the central nervous system. It conveys motor commands to muscle groups and it relays sensory information to the central nervous system. The peripheral nervous system also 'micro-manages' things going on in the body like how fast the heart beats; or how much acid to secrete in order to digest that hamburger. For some bodily functions, the peripheral nervous system handles this completely independently from the central nervous system (digestive processes is a pertinent example). While for other functions, the central nervous system will influence it. The extent of influence usually depends on how complicated the behavior needs to be. If you are fleeing in panic from a rabid dog, for example, your brain will boost your body's ability to run and think quickly. It will do this by regulating bodily systems related to heart rate, blood pressure, and hormone secretion - all via the PNS.
What are the three common degenerative disease of the nervous system?
Three Diseases of the nerve system would be Alzheimer Disease, Broca Aphasia and Cerebello-Olivary Degeneration of Holmes. Hope it helpsss.
What do you mean by nervous system?
Nervous system is a system present in the body of almost all living organisms.it consists of the brain,the spinal cord and network of neves in humans.the main function of nervous system is to conduct,transport and react to the various messages,impulses and various biological processes are dependent on this system directly or indirectly.
Where in the medulla are the neurons that set the basic respiratory rhytm?
The answer is Ventral Respiratory Group or VRG
It contains the rhythm generators "whose output drives respiration".

Two part of brain that control autonomic nervous system?
the medulla oblongata is what controls the sympathetic and parasympathetic nervous system.
What connects your body to the central nervous system?
The central nervous system. Or CNS. you so funny
Path way of the message to the nervous system?
The stimuli will be picked up by the sensory neurons then nerve impulses travel to your spinal cord. Those nerve impulses return to motor neurons that will react (like you pull your hand away, or you yell) as you react the nerve impulses travel to your brain.
