Njenga-dermatome, i-myotome yimihlaba emzimbeni okhonzwa ngenye ingcambu yomgca. Ukwahlukana kukuba i-dermatome yindawo apho i-nervous nerve ihamba endleleni yayo yinkqubo yesantya ephakathi kunye nolwazi malunga nezinto ozivelayo - ukufudumala, intlungu, iitshizi, isikhundla sakho somzimba, indlela elula ngayo imisipha yakho, kunye nokunye. I-Myotomes, ngakolunye uhlangothi, ziindawo apho izithuthi zihamba khona njengoko zifezekisa uxanduva lwabo lokutshintshela izihlunu zakho.
Zombini i-myotomes kunye ne-dermatomes "ziphawulwe," ezibonelela oogqirha kunye nezobuchwephesha ngokwenjongo yokumisela-ngokusekelwe ekuhloleni nasekuhloleni - iingcambu zentsholongwane okanye iminqweno yesigxina esisemgangathweni enokuthi ihlelwe phantsi kwaye / okanye kubangela iimpawu.
I-Myotomes kunye neerermas ziyinxalenye yesimiso se-somatic (yokuzithandela) inkqubo ye-nervous, eyinxalenye yesimiso se-nervous system. Iinkqubo zentambo kunye neentloko zixubana rhoqo.
Imisipha kunye neMisipha, O wam!
Yonke iseli esele emzimbeni wakho idinga ingenelo kwimbilini ukuze uhlale uphilile. Ngaphandle ubuncinane unxibelelwano phakathi kwentsholongwane kunye nemisipha (into ebizwa ngokuba yitoni elinceda kakhulu ukugcina izalathisi zakho zizinzile), i-muscle iqala ukubola.
Olu lunxibelelwano lwenzeka kwindawo ebaluleke kakhulu kwi-cell fibre cell ebizwa ngokuba yi-motorplate. Iselfowuni yesibindi, kunye ne-endplate yaziwa ngokuba yi-neuromuscular junction.
Elinye iselferensi yeselingo ayinalo iimbumba ezininzi. Oku kubizwa ngokuba yiyunithi. Zonke iifiber eziyinxalenye yesivumelwano seyunithi (isebenza) xa i-nervo yayo ichithwa. Yisiphakamiso sonke okanye akukho nto. Ukuze ugweme isisu kunye nesibindi "sitshise," iiyunithi zezithuthi ziya kutshintshwa.
Konke oku kwenzeka kwinqanaba elincinane, khumbula, kodwa kuxhomekeke kubukhulu bemisipha kunye nemisebenzi okwenzayo, iseli ye-nervous isingenakubalwa njengamaqela angama-6-10 e-muscle (cinga iminwe edlala ipiyano, yifake imifuno, yenza , ubhale, okanye imisipha ecaleni kweso elinceda ukugxila, ukukrazula iinyembezi, ukugcina ukhuselekileyo kwindlela kunye nokunye.) kumakhulu (cinga phakathi kwe-back and muscle, apho ukulungelelaniswa okulungileyo kungabalulekanga.)
Enye indlela yokuqonda iiyunithi zezithuthi zivela kumbono we-muscle. Inambuzane emininzi enemizimba iqukethe iqoqo elingenakubalwa kwezixhobo zeenjini.
I-Myotomes-I-Global Nerve-Muscle Persective
Ngoku ukuba uyazi ukuba iyunithi yombane - ukuqonda i-myotome yinto yokubukela izinto kwiimeko ezininzi zehlabathi.
I-myotome yiqela leemisipha kwicala elinye lomzimba elixhaswe ngenye ingcambu yomgca.
Oogqirha basebenzise ulwazi lwabo malunga neendawo ze-myotomes (kunye neerermatomes ) ngexesha lovavanyo lomzimba. Ukufumanisa iimbilini zesigulane ezinokuthi zingaphantsi kobuthathaka bomzimba, zenza iimvavanyo zomeleleyo ze-isometric ngokwemibala ye-myotome.
Ngaphantsi kweli candelo ityati enika amagama amathambo kunye nesenzo abavelisa ngabangenasisiseko kwimisipha enoxanduva, oko kukuthi, imephu.
Ngaphambi kokuba ndikubonise oko, makhe ndixelele nje ukuba inkqubo ye-myotome yokucacisa iyakuthi ibe yintlanzi. Ngamanye amazwi, nangona i-myotomes (kunye neerermomomes) "ifakwe imephu," ngokuqhelekileyo, imimandla ayisoloko ichanekile kwaye ihluke. Kukho ngokuphindaphindiweyo, apho iimbilini ziza kubakho izihlunu ezingenakulungelelaniswa kwimimandla ngaphandle kwezo "zipakiwe ngokusemthethweni".

I-Myotome Dance
Ukuba uhlobo lomntu ofunda ngokukwenza, ndincoma ukuba ukhangele enye okanye ngaphezulu kwevidiyo ze-YouTube ezixutywe ngezantsi. Ezi ziveliswe ngamanyathelo omzimba oncedisayo amaqela amacandelo esikolo (kunye neklasi enye yezobugcisa) ukusuka kulo lonke ilizwe. Ngenxa yokuba ividiyo nganye inamaqela aqinileyo kunye nebuthathaka kwimfundo, mhlawumbi ingumzekelo omuhle ukubheka kuzo zonke. Qaphela: Ininzi yemidaniso yenziwa ngokubetha ngokukhawuleza. Ndicebisa ukuba uhambe ngesantya umzimba wakho (ingakumbi intamo yakho) inokusingatha ngokukhuselekileyo. Oku kunokwenzeka ukuba oku kuthetha ukuhamba ngokukhawuleza ngoko abafundi bezonyango.
Kodwa ke, le mijumbo ingakunika ingcamango enhle malunga noko i-myotomes eyenzileyo ngokwenene, kwaye kutheni kubalulekile.
Kwaye nomculo ulungile kakhulu, naye.
