Jugular Vienna: Anatomy uye Physiology

Jugular Vienna (YaV) kunobvisa ropa kubva nhengo uye nyama yacho musoro cranial vena cava. Ndiye menyika uye kunze.

1. Chokutanga izvi iri kumbonyanya pedyo kure muviri pamusoro, saka unogona kuona panguva dzakasiyana tsandanyama makakatanwa. Riri mune jugular paburi uye inoitisa ropa kubva pamutsipa, chirebvu uye mutsipa ganda, uye ipapo runoyerera dzomukatikati YaV. It ane vharafu mariri uye ichayerera kupinda dzimwe mutsinga akadai:

a) Anterior jugular Vienna - zvinobva muna chirebvu nharaunda, rinotungamirirwa downwards akananga pamusoro sternohyoid tsandanyama. Vaviri vavo, kumativi ose, ivo vanoburukira suprasternal nzvimbo, izvo zvakabatanidzwa ne anastomosis (jugular chinhu chakakombama). Saka, pamberi jugular mutsinga batanidza kuti vaumbe mutsipa tsinga.

b) The rwemberi nzeve Vienna - inoitisa ropa ichibva plexus, riri shure nzeve. It riri seri nzeve.

c) occipital - anotakura ropa kubva venous plexus iri seri musoro, izvozvo yakadururirwa kuputika wokunze yenyukireya, uye dzimwe nguva mukati zvemukati.

g) suprascapular - inopfuura pamwe tsinga uye ane chimiro hunde dzacho mbiri unobatanidza kuguma chikamu chimwe subclavian tsinga.

Jugular Vienna (yokunze) unotora mavharuvhu.

2. A rinokosha iri reDare dzomunyika jugular Vienna. Zvinotora kwarwakabva panzvimbo jugular foramen, riri mujinga dehenya, obliquely runosvika mhiri yose mutsipa pasi pasi sterno-clavicular tsandanyama, zvichiita yayo lateral Zvikamu mujinga pamutsipa.

Kana kutendeukira musoro mhiri, inoenda pamusoro panzvimbo maererano Nzeve uye sternoclavicular sochlenenieya, iri carotid bhegi carotid tsinga uye lateral tsinga.

Zvinofanira kucherechedzwa kuti muuropi, kureva yaro hwakasimba goko vari hurongwa venous midziyo inoyerera kupinda tsinga uye achitsausa ropa akati muviri. Vose vari zvakabatana mumwe nomumwe uye dzinoumba hwakasimba venous sinuses tambo. Saka, ropa riri kusimbiswa zviviri sigmoid sinus achipfuura zvimwe mawindo ari dehenya. Saka inoumbwa kuruboshwe uye kodzero dzakawanda jugular tsinga.

A shoma zvikuru vanobatanidzwa mune rechibharo, iyo bvisa ropa kubva pharynx uye dokeriro, mate omumuviri, nemumuromo uye nasal mhango uye ganda musoro uye mutsipa uye thyroid. Ari YaV kuyerera yomukati uye nezvimwe mutsinga, yakadai se:

a) mberi - zvinobva apasi rushaya kuti confluence pamusoro mutsinga maviri (chiso kumberi uye shure) ndiye akatungamirira downwards uye ipapo namanhede. Haina mavharuvhu.

b) thyroid mutsinga - pematanho arteries uye ichayerera vakapinda pamberi tsinga kana lingual. Vane mavharuvhu.

c) pharyngeal - zvinobva kuna pemvura huro, ivo akandipa tsinga vidian gwara mukanwa, eustachian chubhu. nhamba yavo angava akasiyana, havana mavharuvhu.

g) lingual Vienna - iri pedyo tsinga, asiya, iye orara pamusoro pemvura lingual tsandanyama uye anofambisa nerokuti pamusoro hypoglossal etsinga. Rine mavharuvhu.

Zvinofanira kucherechedzwa kuti vose mutsinga musoro ndivo anastomoses pamwe venous sinuses kuburikidza mapfupa dehenya. Saka, vari iri romukati kukona ziso, seri nzeve, munzvimbo korona. anastomoses izvi kuti zvinobvira kugadzirisa kufurirwa iri dehenya. Uyewo, kana pakati kuzvimba munyama vachishumira nokuisa kuzvimba uropi membranes, inova kutanga zvikuru ngozi.

Saka, Vienna womukati jugular, subclavian unobatanidza kuti, anoumba negomba dhiramu pamusoro tsinga.

Jugular Vienna, kuitwa iri pamutsipa, inoita water drainage ropa kubva munyama uye nhengo musoro uye chikamu vena cava. Inoitwa mbiri mbiri (kwokunze uye nechomukati) izvo kuita zvinokosha Unoshanda murau ropa kuyerera, sezvo chinhu chinokosha kweropa ezvinhu yevanhu.
