Ingqimba engezansi yemisipha yangemuva yangaphakathi iqukethe imisipha emhlane ejulile.
Ngokungafani nemisipha ephuma phambili, imisipha yangemuva yangaphakathi itholakala ngokujulile; Ngamanye amazwi, basondelene namathambo kunesikhumba. Imisipha yangemuva yangaphakathi ihlukaniswe zibe izingqimba ezintathu: Ingqimba engaphandle, isendlalelo esiphakathi, nocansi olujulile.
Lesi sihloko sikhuluma ngendwangu yangaphandle yemisipha yangemuva yangaphakathi.
Umthamo ongokoqobo
Njengoba igama liphakamisa, isendlalelo sangaphandle semisipha yangemuva yangaphakathi ihlala phezulu kwezinye izendlalelo ezimbili kuleli qembu. Isendlalelo esingenasici sakhiwa ngokuphelele emisipha ye-splenius - splenius cervicis ne-splenius capitis. Ngokufanayo imisipha ye-splenius igubungela ama-paraspinal ahloselwe ngokuqondile (okujulile futhi afaka isendlalelo esiphakathi semisipha yangemuva yangaphakathi).
Igama elithi splenius libhekisela ebhanini. (Kuthathwa egameni lesiLatini elibizwa nge-bandage, okuyi-"splenion") Ngomqondo othile, ukubopha imishini yilokho imisipha ye-splenius eyenza ama- paraspinals (ungqimba oluphakathi ngaphakathi) - kanye nalawo misipha ehamba phambili ungqimba olujulile lwangaphakathi. Imisipha ye-splenius (futhi ngenxa yalokho ungqimba olungenasici wezinsizwa zangemva zangaphakathi) lizobamba lezi zigaba ezijulile endaweni.
I-splenius captius ne-cervicalis zimboza indawo ukusuka phansi entanyeni (C-7) phansi engxenyeni engenhla yomshoshaphansi we-thoracic (T-3 noma i-T-4.) Baqala enkabeni yomgogodla kulawo mazinga ndawonye yenza "V" ukuma - ngezinhlangothi ze "V" obukhulu kakhulu futhi indentation central aphansi kakhulu.
I-splenius capitis imiswe ngenhla kwe-splenius cervicalis kodwa, futhi, lezi zindlela ezimbili zenza isimo esisodwa futhi zenze ndawonye.
Amafayili omzimba ngamunye we-splenius capitis kanye ne-cervicalis ahamba nge-diagonal. Kusukela emkhatsini womgogodla, ama-fibers angena ku-skull ne-vertebrae yomlomo wesibeletho (C1-C3 noma C4.)
Ake sifunde okunye mayelana nemisipha ngayinye yesendlalelo esingenasisekelo semisipha yangemuva yangaphakathi.
Splenius Capitis
Njengoba kuphawuliwe ngenhla, imisipha ye-splenius capitis iqala phakathi nendawo yomgogodla, ihlukanisa amazinga phakathi kwe-vertebra yakho yesi-7 yomlomo wesibeletho kuya kweyesi-3 noma yesine (ihlukahluka) i-thoraic vertebrae. Ngokuqondile, i-splenius capitis ivela ligamentamenta ye- nuchal, okuyinto ligament eqinile kakhulu entanyeni, ngokwayo evela ligament ezixhuma amathiphu izinqubo zakho spinous kuze kube phansi umgogodla. (Lokhu kuthiwa yi-ligament ephezulu.) I-spelnius capitus nayo ivela ezinkampanini ze-C7-T3 noma i-T4.
Umsila we-splenius capitis uvele uphakamise futhi uphumelele ukunamathisela ku-skull yakho ezindaweni ezimbili: Inqubo ye-mastoid, ekhona ngemuva nangaphezulu kakhulu kwezindlebe, nasemgqeni we-nuchal we-skull, engemuva i-skull yakho kodwa ezingeni eliphezulu kunenqubo ye-mastoid.
USplenius Cervicalis
Njenge-splenius capitis, i-splenius cervicalis iqala emkhatsini we-spineus, ihlukanisa amazinga phakathi kwe-vertebra yakho yesi-7 yomlomo wesibeletho ku-3rd noma 4th (ihlukahluka) i-vertebrae ye-thoracic. Ngokuqondile, i-splenius cervicalis ivela ligamentamentha ye-nuchal, okuyinto ligament eqinile kakhulu entanyeni, ngokwayo evela ligament ezixhuma amathiphu izinqubo zakho spinous yonkana phansi umgogodla. (Lokhu kuthiwa yi-ligament ephakeme kakhulu.) I-spelnius cervicalis ibuye ivela ezinkampanini ze-C7-T3 noma i-T4.
Ngokungafani ne-splenius capitis, i-splenius cervicalis ifaka izinqubo ezithinta izintambo zangaphambili ezintathu noma ezine eziphezulu zomlomo wesibeletho, ngokwamanye amazwi ku-C1-C3 noma ku-C4.
Uma izinhlangothi zombili zomshini we-splenius zisebenza ndawonye, umphumela unweba intamo, okulingana nokubuyisela ikhanda emuva emuva kwentamo. Uma uhlangothi olulodwa kuphela luyaxhuma, imisipha ye-splenius isiza ukugoqa futhi / noma ukushintshanisa intamo eceleni kocansi.
