Lakar Vienna (YaV) kawar da jini daga cikin gabobin da kyallen takarda da kai a cikin girman kwanyar vena cava. Yana da ciki da kuma na waje.

1. Na farko cikin wadannan shine a wani fairly kusa nesa daga jiki surface, don haka shi za a iya gani a cikin Game da tsoka tashin hankali. An located a cikin lakar tsagi, kuma zai gudanar da jinin daga wuyansa, Chin, kuma wuyansa fata, sa'an nan gudana a cikin ciki YaV. Yana yana da wani bawul a shi da kuma daga ƙarƙashinsu a cikin sauran jijiyoyinmu kamar:

a) agara lakar Vienna - fãra a Chin yankin, directed zuwa ƙasa zuwa ga surface sternohyoid tsoka. Biyu daga gare su, a garesu, suka gangara zuwa cikin suprasternal sarari, wanda suna da alaka da anastomosis (lakar baka). Saboda haka, gaban lakar jijiyoyinmu ci ta samar da wata wuyansa jannayẽnsa.

b) A na baya kunne Vienna - gudanar da jini ya fito daga cikin plexus, wanda aka located bayan da kunne. An located a baya da kunne.

c) occipital - daukawa jini daga venous plexus a baya na kai, shi ne zuba a cikin matsanancin nukiliya fashewa, da kuma wani lokacin a cikin ciki.

g) suprascapular - ya wuce tare da jijiya da kuma yana da nau'i na biyu kututturan a haɗa daya karshen sashe na subclavian jannayẽnsa.

Lakar Vienna (m) qunshi bawuloli.

2. A musamman rawar da ake buga ta da ciki lakar Vienna. Yana daukan ta source a wuri na lakar foramen, wanda aka located a gindi daga cikin kwanyar, à kara fadin duka wuyansa saukar karkashin sterno-clavicular tsoka, sakamakon a kaikaice sassan a tushe na wuyansa.

A cikin hali na juya shugaban zuwa wancan gefe, shi da ke a wurin dangane da kunne da kuma sternoclavicular sochlenenieya, dake a cikin carotid jakar carotid jijiya da kuma a kaikaice jijiya.

Ya kamata kuma a lura da cewa a cikin kwakwalwa, wato a cikin m harsashi ne tsarin venous tasoshin sunã gudãna a cikin jijiya da kuma karkatar da da jini daga jiki ce. Dukkan su suna da alaka da juna da kuma samar da wani m venous sinuses igiyar. Saboda haka, jini yana mayar da hankali a biyu sigmoid sinus wucewa ta hanyar wasu takware a cikin kwanyar. Kamar wancan kafa ta hagu da kuma dama ciki lakar jannayẽnsa.

A 'yan mafi suke kunshe a cikin aikin gandu, wanda cire jini daga pharynx da maƙogwaro, salivary gland, baka da kuma hanci kogo da kuma fata na kai da wuya da kuma thyroid. A ciki YaV kwarara da kuma sauran jijiyoyinmu, kamar:

a) gaban - fãra daga cikin ƙananan muƙamuƙi zuwa mahaɗar tsakãninsu biyu jijiyoyinmu (gaban fuska da kuma mayar) ne directed zuwa ƙasa sa'an nan na baya. Yana yana da wani bawuloli.

b) thyroid jijiyoyinmu - bi da jijiyoyi da kuma daga ƙarƙashinsu a cikin gaban jijiya ko da lingual. Suna da bawuloli.

c) pharyngeal - Kwatsam daga surface na makogwaro, suka infused jannayẽnsa vidian tashar palate, eustachian tube. Adadin su iya zama daban-daban, ba su yi bawuloli.

g) lingual Vienna - located kusa da jijiya, ya bar ta, ta ta'allaka saukar a kan surface na lingual tsokoki da kuma gudanar da layi daya da hypoglossal jijiya. Yana yana bawuloli.

Ya kamata a lura cewa duk da jijiyoyinmu daga cikin shugaban ne anastomoses da venous sinuses ta hanyar da ƙasũsuwan da kwanyar. Saboda haka, suke located a ciki kusurwa na ido, bayan da kunne, a yankin na kambi. Wadannan anastomoses sa shi yiwuwa a daidaita matsa lamba a cikin kwanyar. Har ila yau, a cikin hali na kumburi da kyallen takarda sunã bauta wa, ta wucewa kumburi kwakwalwa membranes, wanda shi ne quite m sabon abu.

Saboda haka, Vienna ciki lakar, subclavian haɗa da, Forms m ganga saman jannayẽnsa.

Lakar Vienna, ana located a cikin wuyansa, sa da outflow na jini daga kyallen takarda da kuma gabobin da kai, kuma shi ne wani ɓangare na vena cava. Ya kunshi nau'i-nau'i biyu (external da ciki) wanda yin muhimmanci ayyuka a cikin tsari da jini ya kwarara, kamar yadda wani ɓangare daga cikin jijiyoyi na mutum.
