Sezvinorehwa nezita racho, unhu husingarevi hwemashure ekudzokera shure huri pamusoro pezvimwe zvikamu zviviri muboka iri. Icho chinyorwa chakanaka chinoumbwa zvachose nemisimba ye splenius - splenius cervicis uye splenius capitis. Pamwe pamwe nemisumbu yep splenius inovhara paraspinals inotenderera (iyo yakadzika mukati uye inosanganisira yakatenderera yakasara yemashure mushure.)
Shoko rokuti splenius rinoreva bhanji. (Inotorwa kubva muchiLatini izwi rebandage, iro rinoreva "splenion") Uye nenzira imwe, mabhanhire ndizvo zvinoshandiswa nemasipinus e splenius kumapasipasi (ari mukati-kati mukati-kati) - uyewo kune mitsipa yakatenderera yakagadzirwa iyo yakadzama yakadzika mukati. Misi yep splenius (uye naizvozvo iyo yakasara yepamusoro yemisungo yakadzoka kumashure) inobata kubata zvidimbu zvakadzika munzvimbo.
The splenius captius uye cervicalis vanofukidza nzvimbo kubva pasi pemutsipa (C-7) kusvikira kumucheto wepamusoro wepfumbu yeTra 3 (T-3 kana T-4.) Dzinotanga pakati pepamusoro pamakumbo iwayo uye pamwe chete vanoita "V" maitiro - pamwe nemativi e "V" akareba kwazvo uye iyo indentation inenge isina kudzika.
Iyo splenius capitis inomira pamusoro pe splenius cervicalis asi, zvakare, iyo mbiri inoumba chimiro chimwe uye inoshanda pamwe chete.
Iyo yemasikironi yemasikisi e splenius capitis uye cervicalis inotarisana pane diagonal. Kutanga pave pakati pepamusoro pemusana, iyo fiber inowona kusvika kuhenya uye cervical vertebrae (C1-C3 kana C4.)

Splenius Capitis
Sezvambotaurwa pamusoro apa, s splenius capitis musisi inotanga kusvika pakati pepamusoro pemusana, iyo inotarisa hutano pakati pe 7t cervical vertebra yako yechitatu kana yechina (iyo inofananidzwa) thoracic vertebrae. Kunyanya kunyanya, iyo splenius capitis inomuka kubva ku nuchal ligament , iyo inonyanya simba guru mumutsipa, iyo inobva kubva ku ligament iyo inobatanidza mazano emitambo yako yepineti yose kusvika pasi. (Izvi zvinonzi "supraspinous ligament"). Sipelinius capitus inomukawo kubva kumagetsi eC7-T3 kana T4.
Iyo splenus capitis muscle inotanga kumusoro nekubuda kunamatira kuhenya rako pane 2 nzvimbo: Utambo hwemastoid, huri kumashure uye kusvika pasi pacho pese nzeve, uye kumutsara we nuchal wehenya, iri kumashure dhehenya rako asi pazinga rakakwirira kudarika mastoid.
Splenius Cervicalis
Sezvakaita splenius capitis, the splenius cervicalis inotanga pakati pepakati pemusana, iyo inowedzera mazera pakati pe 7th cervical vertebra yako yechitatu kana yechina (iyo inofananidzwa) thoracic vertebrae. Kunyanya kunyanya, iyo splenius cervicalis inomuka kubva ku nuchal ligament, iyo inonyanya simba guru remutsipa, pachayo inotangira kubva mumirairo iyo inobatanidza mazano emitambo yako yepineti yose kusvika pasi. (Iyi inonzi "supraspinous ligament"). The spelnius cervicalis inomukawo kubva kumagetsi eC7-T3 kana T4.
Kusiyana ne splenius capitis, the splenius cervicalis inonamatira pamatenderedzwa ekutenderera emapfupa matatu okutanga kana 4 emusoro emutsipa (mumutsipa), mune mamwe mazwi paC1 - C3 kana C4.
