It started with a facial paralysis on the left side 23 years ago, followed by total deafness in one week on the same page. Then continued and felled nerve after nerve down 5, 6, 7, 8, 9, 10, 11, 12 in that order.
When it passed the 9 and 10 began my sleeping problems occur, though I did not understand it then.
But all the other nerves were labeled totally obvious. especially when you see the image on the face of the fifth nerve. Exactly the prevalence of numbness in the face, the lower of the three shadings.
All this, from 5th to 12th cranial nerve took a few months, and now 23 years later, it is my biggest problem ache from Trapezius Muscle cranial nerve 11.
Look especially at the cranial nerve 9 and 10, it's them that control breathing.
The pieces fall into place.
Cranial nerve IX, 9
glossopharyngeal nerve
Heavy - pharyngeal nerve, Taste - pharyngeal nerve, the ninth cranial nerve , Caroticusnerven , Sinus Nerve , Heringska nerve, Ramus sine carotici n.IX
connects to the medulla behind / dorsally on the olive, below the eighth cranial nerve .
Cranial nerve 9 is the main taste nerve.
It is fitted with two sensory ganglia , one just inside and outside the nerve exit the skull base .
Nerve supplies motor m stylopharyngeus and together with the tenth cranial nerve svalgflätan ( pharyngeus plexus ) . It sends parasympathetic signals to the parotid gland . Ninth cranial nerve conveys sensation from the middle ear / drum cavity and pharynx from the tonsils .
For kran.nerv 9 hear a very special intestinal sensory part ( visceral nature 's ) : sinus nerve ( caroticusnerven , the Heringska nerve) . This is about the primary nature of the two sensory organs (a and b ) in the upper part of the carotid artery that records :
a) blood pressure, which are known as : carotid sinus . Stimulated sensory cells in the carotid sinus of increased pressure (either an internal pressure increase in the blood vessel or an external mechanical influences) so this leads to a reflex decrease in blood pressure and a heart rate reduction.
b ) the amounts of oxygen and carbon dioxide in the blood, via chemoreceptorer in something called the carotid . Flags oxygen levels in the blood and / or rising carbon dioxide levels is accomplished through the sinus nerve and connections in the medulla increased respiratory rate , increased breathing depth and breathlessness .
Cranial nerve X; 10
vagus
The wandering nerve, Vagus tenth cranial nerve
Deleted from the medulla behind / dorsally on olives and below / caudal of the ninth cranial nerve . Vagus extends from the skull base down through the neck joins the esophagus passes through the chest cavity , cuts through DIAPHRAGMA along with the esophagus and divides up into their end branches ( all parasympathetic ) in the upper part of the abdominal cavity.
Vagus has two sensory ganglia , one just inside and an outside exit hole in the skull base .
The nerve supplies motor pharyngeal muscles (along with kran.nerv 9 ), soft palate / gomseglets muscles (along with kran.nerv 5 ) and is in charge of vocal cord muscles.
Vagus nerve is the major parasympathetic nerve - preganglionic ( visceral efferens ) nerve fibers - which during its wandering course affects surrounding inälvsorgan throat, chest cavity and abdominal cavity and that convey sensory input - visceral nature 's - thence to Nucl. solitarius in the medulla . The visceralafferenta wires is 4 - 5 times as many as they visceralefferenta .
