Does synesthesia affect the nervous system?
I am not quite sure what you mean by this. Could you explain more?
If you mean what types of synesthesia are in existence, then the answer is oh, so many! Think of any two senses (ex. touch and sight), and you can cross them. Here's a short list of major types for an example. Note that there are many sub-categories within these.
- Sight -> sight, sound, taste, touch, smell, emotion, concept
- Sound -> sight, sound, taste, touch, smell, emotion, concept
- Taste -> sight, sound, taste, touch, smell, emotion, concept
- Touch -> sight, sound, taste, touch, smell, emotion, concept
- Smell -> sight, sound, taste, touch, smell, emotion, concept
- Emotion -> sight, sound, taste, touch, smell, emotion, concept
- Concept -> sight, sound, taste, touch, smell, emotion, concept
If you mean how does synesthesia affect the daily lives of synesthetes, then that's another topic altogether, and the answer differs with each synesthete. Most say it doesn't negatively affect them much or at all; in fact, it is a helpful trait to have because it can be used as a memory tool or something.
Others have negative responses to certain things and that can range from a minor annoyance to something that really affects how you live your life. Again, this will depend on the specific person, but an example is Ordinal Linguistic Personification. This is where personalities and genders are attributed to letters, numbers, chairs, trees, and so on. In math, for example, having certain numbers beside one another can cause a problem for a synesthete because the numbers might not get along or might be fighting one another.
Lastly, sometimes the sheer number of synesthetic responses a person gets at one time can be overwhelming. For instance, a person with multiple types of synesthesia might get overwhelmed in a loud, crowded room. Not only would that be overwhelming on a normal level (too loud, too crowded, too much going on) but then the person gets the colors of the voices, the colors of the people's personalities, the taste of the words, the shapes of the smells, and so on. Again, it depends on the individual person.
Yes. The peripheral nervous system (PNS) functions primarily to connect the central nervous system (that is, the brain and spinal cord) to the rest of the body in order to allow the brain to direct the body to perform its various functions. The PNS is divided into two parts. The somatic system controls voluntary actions, such as walking and other movements; the autonomous system controls involuntary actions, such as breathing and digestion.
What part of the nervous system is affected if someone cannot walk after an accident?
The damage is to the voluntary nervous system, that controls muscular movement. This is associated with either brain or spinal injuries.
What neurons make up the peripheral nervous system?
Unified network of communications, but on an anatomical basis, it is divided into two primary portions. Which peripheral nervous system is the second portion.
The spinal cord
The peripheral nervous system consists of autonomic and the somatic nervous systems.
How is the skin involved with the nervous system?
The skin has specialized sensors that are imbeded into it such as:
Hair follicle endings: responds to hair displacement
ruffini endings: responding to pressure on the skin
krause corpuscle: responding to pressure on the lips or tongue
Pacinian corpuscle: which responds to vibration in deep layers of dermis
Messiner corpuscle: which responds to vibration in the dermis of glabrous skin
or free nerve endings: which respond to mechhanical thermal or noxious stimulaiton
all of these receptors pick up things from the environment and send them to the brain for perception and identification.
What are the functions and each parts of nervous system?
The function of the nervous system is to enable us to feel our surroundings. The five senses (sight, touch, hearing, taste and smell) have different sensory neurones in various parts of the body. The most sensitive parts of the body are the fingertips and lips, which have far more sensory neurones per square centimetre than other parts of the body. The nerve impulse travels from the sensory neurone, across a synapse (the gap between the end of one neurone and the dendrites (fingers) of the next) and reaches the next neurone. The signal reaches the coordinator (either the brain or spinal cord) and is then sent to a certain part of the body via a motor neurone, which eventually reaches the muscle and causes a movement. The nervous system is effected by stimulants and depressants, such as alcohol and drugs, which change the speed of reaction times. Parts_and_function_of_nervous_system
What are the structural parts of the nervous system?
he nervous system derives its name from nerves, which are cylindrical bundles of fibers that emanate from the brain and central cord, and branch repeatedly to innervate every part of the body.[2] Nerves are large enough to have been recognized by the ancient Egyptians, Greeks, and Romans,[3] but their internal structure was not understood until it became possible to examine them using a microscope.[4] A microscopic examination shows that nerves consist primarily of the axons of neurons, along with a variety of membranes that wrap around them and segregate them into fascicles. The neurons that give rise to nerves do not lie entirely within the nerves themselves-their cell bodies reside within the brain, central cord, or peripheral ganglia.
What are the two principal divisions in the nervous system?
The Central Nervous System and the Peripheral Nervous System or CNS and PNS are the two main divisions of the nervous system. The CNS consists of the spinal cord and brain and gathers info. in the spinal cord and up to the brain for interpretation and the brain sends out a signal as a response. The PNS is made up of sensory receptors and motor effectors. ( It is basically all the parts besides the brain and spinal cord.) The PNS also has cranial nerves and spinal nerves.
What structures and functions of the nervous system are affected by meningitis?
It can do brain damage to your brain. The cause of it is viruses, fungi, normally bacteria.
Well, Meningitis is caused by bacteria flooding the cerebrospinal fluid which is found in between the meninges (layers of membranes surrounding the brain and the spinal cord) so I'd say that Meningitis can do damage to the brain and the spinal cord.
Functions of cerebellum in nervous system?
The most important function of the cerebellum (if your a student the most you will probably be tested on in a gen bio class) is the control of balance and fine motor function, like walking.
Name the two types of nervous tissue?
Neurons and neuroglia the neuron known as the functional unit is the actual nerve cell. It transmits the impulses of the nervous system.. A neuron consists of three basic parts: a cell body, one axon, and one or more dendrites..
What is the division of the nervous system that helps the body react to pain is the?
The division of the nervous system that helps the body react to pain is known as the sympathetic nervous system. This is what will trigger responses to stressful situations.
When you learn something new do you grow new neurons?
That is a complicated and very good question. In humans (mammals) neurons are formed during development throughout the cortex. At adulthood, this continues only in the hippocampus and olfactory bulb. Therefore the rest of the cortex is made of all the same neurons for the rest of your life (n.b. you can lose them). Therefore learning new things is probably the result of neuro-placticity rather than neurogenesis.
However, There are two general types of memory; episodic and semantic. Episodic are the ones that you can imagine because you experienced them. As opposed to semantic- dry info you've studied.
Episodic memories seem to be consolidated by the hippocampus which may play memories back during REM sleep. This may be the result of neurogenesis. However, the new cells that are formed will not be the loci of the memories they are the mechanism of storing the memories in the neocortex.
Long term effects of exercise on tendons?
Can wear away the muscle walls and lead to aches and pains that build up gradually over time. This can cause discomfort if one indulges in over exercise, so its best to do everything in moderation and not push yourself beyond the limits. Joint pain- arthritis is common and stiffness may occur if care isn't taken.
What body system is the fast-acting control system?
The nervous system is the fast-acting control system.
How many pairs of nerves branch off of the spine?
SPINAL CORD31 Pairs - Spinal NervesCervical8 pairThoracic12 pairLumbar5 pairSacral5 pairCoccyx1 pair
What is the main function of the perpheral nervous system?
The main function of the peripheral nervous system is to connect the central nervous system to the limbs and organs. It helps coordinate body movements and receiving external stimuli.
It is also the system that controls the "fight or flight" response.
The central nervous system is responsible for coordinating all the information that is received from the body, whereas the peripheral nervous system connects the central system to the organs and limbs, relaying communication to and fro.
How can alcohol effect homeostasis?
Yes to put it simply. Alcohol blocks the receptors that tell your body when your bladder is full, so your bladder keeps thinking it is full when it is not, this can cause dehydration, which can cause headache as seen in hangovers
How do the organs of the nervous system work together?
The central nervous system is the brain and the spinal cord, and the peripheral nervous system is the motor and sensory neurons. So your sensory neurons are what help you feel things, like cold and hot and pain, etc. This is a pretty open-ended question, but I would say they keep us alive when they work together by alerting of us of our environment.
