Glossopharyngeal nerve

Glossopharyngeal nerve

Glossopharyngeal nerve 

  Pair of cranial nerves IX (p. glossophagyngeus) mixed nerve contains motor, sensory and parasympathetic (secretory) fiber, has 4 cores, which are located in the posterior part of the medulla oblongata. 

The double nucleus, nucl. ambiguus (in common with a pair of X), located in the middle part of the medulla oblongata, in front and lateral nucleus hypoglossal nerve. 

Axons of cells form the core motor branch of the glossopharyngeal nerve, which innervates the muscle only shiloglotochnuyu (ie stylopharingeus). When ingested, this muscle raises the pharynx and larynx. 

Dual core (nucl. ambiguus) is a bilateral cortical innervation. 
The nucleus of a single path, nucl. solitagius sensitive, in common with the vagus nerve and the intermediate section is located in the lateral medulla oblongata. It takes sensitive taste fibers from the anterior two thirds of the tongue on the system of intermediate nerve and the tympanic chord, gustatory information from the posterior third of the language kernel gets the trunk of glossopharyngeal nerve (part of the trunk of the vagus nerve). 

Sensitive nucleus, nucl. alae cinereae (in common with a pair of X), is located dorsolateral to dual core and provides the sensitivity of the larynx, trachea, pharynx, soft palate, 
middle ear. 
  Lower salivary nucleus. nucl. salivatorius infegiog (parasympathetic), located in the medulla oblongata between the nucl. ambiguus and the nucleus of the olive. Innervates the parotid glands. 

Sensitive nucleus (nucl. alae cinegea), the total for the IX and X cranial nerves, has a bilateral cortical connections. 

Glossopharyngeal nerve roots in the form of 34 out of the medulla oblongata in the groove between the olive and restiform body. 

These roots are connected into a single trunk, which, through the jugular outlet orifice of the cranial cavity along with X and XI nerves. 

Next glossopharyngeal nerve descends on the lateral surface of the neck and divides into branches. 
Outside the skull glossopharyngeal nerve lies at first between the internal jugular vein and internal carotid artery, then runs along the rear edge shiloglotochnoy muscle. Then the nerve passes through the side wall of the pharynx and, reaching the edge of language, is divided into terminal branches: tympanic nerve, a branch shiloglotochnoy muscles, sinus branch, almond branches, pharyngeal, and lingual branches. 

Sensitive glossopharyngeal nerve fibers originate from the upper (intracranial) node gangl. Supegius, located in the jugular opening, and bottom (vnecherepnogo), which lies at the exit from the jugular hole in a rocky hollow feasts ides of the temporal bone. The peripheral processes of cells of upper and lower ganglion is followed in the branches of the glossopharyngeal nerve trunk in general and with the motor fibers innervate the eardrum, external ear canal, the mucous membrane of the pharynx, the back of the soft palate. tongue, tonsils, tympanum, 
eustachian tube, the rear third of the tongue. 

Central spines are in the medulla oblongata, divided into 2 branches: a brief downward to the core of a single path (nucl. tgactus solitagius) and a longer rising to a sensitive nucleus (nucl. alae cinegea). 
The nucleus of a single path (nucl. tgactus solitagius) influences taste sensitivity of the language on the following main channels: n. lingualis and chogda tympani from the front two-thirds 
tongue (1 neuron in gangl. geniculi) and IX and X nerves from the posterior third of tongue (1 neuron in gangl. supegius and gangl. infegius). 

From the nucleus of a single path (11 sensory neuron) depart fibers to the nuclei of the thalamus opposite side. Next fibers from the nuclei of the thalamus pass through the posterior third of the rear legs of the internal capsule and suited to the cortical gustatory center in the lower section postcentral gyrus. The defeat of these nuclei or fibers is accompanied by a breach of taste, and irritation of the development of gustatory hallucinations. 
Motor nucleus (nucl. ambiguus), the total for the IX and X pairs, provides the motor innervation of the muscles of the soft palate with bilateral cortical connections. 

As part of glossopharyngeal nerve are also parasympathetic efferent (secretory) fibers to the parotid gland. These fibers originate in the vegetative lower salivary nucleus (nucl. salivatogius infegiog), cells which are scattered in the reticular formation of medulla oblongata. 

With the defeat of nucl. salivatogius infegiog arises xerostomia due to hypofunction of the parotid salivary gland. 

  Symptoms defeat 
  Isolated glossopharyngeal nerve lesions are rare. The only sign of violation of motor nerve function IX can be expressed in unilateral small paresis soft palate. Swallowing disorders are usually mild, as the innervation of the muscles of the throat pain necks often lingers through the branches of the vagus nerve. 
Pathology of nerve IX may be accompanied by a decrease in secretion of the parotid gland, decreasing the sensitivity of the posterior wall of the pharynx and soft palate. There is a loss of taste sensation on the posterior third of tongue. 
With stimulation of glossopharyngeal nerve may develop muscle spasm, glossopharyngeal gutturotetany, as well as paresthesias, increased salivation, or pain.

Thank you that was very helpful

That’s a smart answer to a tricky quseoitn

I finally get to see the manju falmiy in all its sticky sweet glory! I love how the baby looks all cozy in its blanket. The layout looks nice. I like it. But since I’ve only watched/am familiar with about 4% of anime evah produced (maybe a bit more since I don’t keep track of hentai), I don’t know who the catgirl is. Her fish cake is making me hungry, though. *chomp* Hm, catfish and manju In any case, I was wondering if the layout will be using gravatars. I looked around in the help menu under Site Admin and it appears that gravatars can be used with the blog’s layout. I can’t just pick which image to use in my replies. I would very much like to use a gravatar that isn’t that baldy ghostly dude. I’m neither of those. XDNotice how I butter you up and then start making pushy demands?

Your answer lifts the inigeltelnce of the debate. [url=]iylveaty[/url] [link=]gmfmjdl[/link]

that email would be enough for me to move. after all, it is YOUR blog and you shulod have complete control over it. i haven’t heard many good things about today. that’s my opinion. have a great day my dear friend…hugz!

If you remove your blog from them make sure you detele all your content from there! I have heard that when you leave, if you don’t remove then it becomes the property of and they can use it how they want.

Yahoooo u finally shcwtied to WordPress (there are a lot of plugins for wordpress on the Wired ) Now just pick a good series and write an article cause i don’t know what to pick to read next. Preattttyy please!!!!

Mais je connais e7a, il y a meame eu un film avec Jim Carrey qui juoait le rf4le du chat de Seuss. Je vends le roman de ce chat dans mon rayon cadet.J aime bien ce qu il fait.

verything osted was ver l gi al. ut, wh t ab ut this? what f y u added a llttie c nt nt? am not suggest ng yοur information i not goo , h eve what if you addeda headl ne that m kes people want more? mean ow To U e Pint rest oBoost Your Goοgle Ranking St at gie For Small usiness | Internet M rketingSt ategies | Soc al Media | Website Des gn is kinda vanilla.You m ght eek at Yahoo’s front page and note how they create post titles to grab people to open the links. You might add a related video or a related picture or two to grab people excited about what you’ e written.Just my inion, it might ma e your posts a llttiebit mο e interesting.

it certainly could be a pihencd nerve, or a slight muscle pull also. either way one should be careful in treating it. pihencd nerve(s) can be felt down the back of one’s leg and also can be quite painful at times. seeing a doctor is always a good idea although there isn’t much they can do after diagnosis, except surgery and or medication. surgery bad, pills bad stretching good, breathing good, good diet good, heating pad good.don’t recommend chiropractors either but i’ve heard they can careful and good treatment: 2 aspirin, followed by heat treatment, followed by slow and thorough stretching of lower body.

i think it’s a sciatic nerve don’t know if spleled that right, but i get that if i lift too heavy doing legs that day at the gym or tweak my leg a certain way. I know what you are talking about cause i’ve almost fallen over trying to get up. I went to kaiser and all they did was take x-rays and give me muscle relaxants that put me out. other than that i have no idea how to make it better, the muscle relaxants didn’t even really help, just made me out of it, still felt the pain.

Hello there I am so glad I found your blog page, I really found you by error, while I was sihecarng onYahoo for something else, Anyhow I am here now and would just like to say thanks a lot for a marvelous post and a all round thrilling blog (I also love the theme/design), I don’t have time to go through it all at the moment but I have bookmarked it and also added your RSS feeds, so when I have time I will be back to read a lot more, Please do keep up the awesome job.

That’s what you’re going to read in this article too. You sulohd pay attention to how your website ranksfor various keyword phrases (I recommend the use of Google’s Webmaster Tools), but you don’t want tostress out about this. The companies and associations are such that they can be needed tocarry out a lot of the functions, procedures and processes which are needed by the dissimilar divisions of society and by the common public of the world.

My developer is trinyg to convince me tomove to .net from PHP. I have always disliked the idea because of the costs.But he’s tryiong none the less. I’ve beenusing Movable-type on a number of websites forabout a year and am nervous about switching to another platform.I have heard good things about Is there a way I canimport all my wordpress posts into it? Any help would be really appreciated! [url=]mmczmzavg[/url] [link=]qdobla[/link]

Sluhovestibulyarny nerve
Sluhovestibulyarny nerve    Sluhovestibulyarny nerve sensitive nerve is the conductor of the special sensitivity of the organ of hearing and balance, and consists of 2x functionally different parts of the vestibular (pars vestibularis) and hearing (pars cochleagis).        The auditory part (auditory nerve) provides transmission of sound stimuli. Sound waves are perceived by specific receptors spiral organ (Corti’s). By petseptoram suitable peripheral processes of bipolar cells of the spiral node, located in the cochlea of the labyrinth.
An investigation of oculomotor muscles
An investigation of oculomotor muscles    All oculomotor function are studied in the middle position of the head and look at the patient directly (primary position).  Attention is drawn to the width of the eye slits of their value. Normally, the upper lid should not go to the area of the pupil. If it comes, it is ptosis (or poluptoz).       To investigate the function of muscles, elevating the upper eyelid (for Burke), pressing the finger skin in eyebrows, asked to look up.
Abducens nerve
    Abducens motor nerve, innervates the lateral rectus muscle eye. By connecting the branches in the trunk of the nerve included autonomic and sensory fibers.  Abducens nucleus (nucl. abducens), which consists of large efferent nerve cells located in the tires (tegmentum) bridge at the bottom of the IV ventricle, near the middle  line, more kperetsi.  The trunk of the nerve leaves the brain at the posterior edge of the bridge between him and the pyramid of the medulla oblongata.
Trochlear nerve
  Trochlear nerve (purely motor) originates in the motor, located in the midbrain at the bottom of the aqueduct of Sylvius at the level of the lower tubercles chetverololmiya backward from nuclei III pair. Fibers are caudal. Do a complete re cross behind aquaeductus cegebgi. This is the only nerve that appears not on the basis of the brain, but on the dorsal side of the brainstem. Pierced cavernous sinus. Through fissuga ogbitalis supegiog penetrates into the orbit outside annujus zinni and reaches the top  oblique muscles of the eye.
oculomotor nerve
  This nerve is mainly motor, but it also contains parasympathetic fibers to the smooth muscles of the eyeball, sympathetic fibers and a small number of sensitive fibers. Conglomerate nuclei III couples located in the central gray matter of the midbrain (at the bottom of the IV ventricle, at the level quadrigemina). Provision is large-(somatic) and small cell (parasympathetic) nucleus. By somatic are paired zadnelateralnye and anteromedial nucleus (nn. dogsolategalis et ventgomedialis), as well as unpaired central nucleus (n.
