Inkqubo skeletal kunye namaqela umsipha ezinkulu

inkqubo dystrophy ibhekisa enye yeendlela ezisezantsi yebhayoloji ezibalulekileyo apho umzimba owenza iintshukumo ezahlukeneyo.

It angamelwa njenge iseti kwimicu izihlunu ekwaziyo ukusikwa. Imicu inamathelene zizithungu, ezenza izihlunu njengamaziko ezizodwa okanye ngokwabo ufake nezibilini. Muscle ubunzima liphezulu kakhulu ngaphezu koko ezinye imizimba: kwezinye izilwanyana kuba-50 ekhulwini ubunzima bomzimba, kwaye umntu - 40 ekhulwini. inkqubo dystrophy esiguqula amandla ekhemikhali ibe ubushushu namandla ngoomatshini.

musculature kwemisipha

Xa ekuyo, musculature dystrophy yahlulahlulwe maqela alandelayo:

• Somatic, iqulethe izihlunu ngaphakathi ukudalwa imilenze. Oku kuquka umsipha skeletal.
• Visceral (inxalenye kwanangezibilini). Kuyinto izihlunu anencasa inhliziyo.

Inkqubo kwemisipha woMntu

imisipha skeletal ukuba striated kwaye esicalanye. Bona apha emathanjeni yaye zezindlu ubude ifayibha ka 1-10 cm.

ifayibha nganye imisipha - ukuba kukho icytoplasm undifferentiated (sarcoplasm) kunye umphakathi ngakumbi amalungiselelo kwi kwimida ethile. Kwimida iquka myofibrils ngokwahlukeneyo striated. It ezingqonge kwimiphetho esingxobeni ngaphaya (sarcolemma), nto leyo equka fibrils collagen. Iqela elincinane kwimicu ingqongwe endomysium; iikhompawundi kwemisipha zomzimba iinyanda okuzenzela, kwi-peremizy ongaphakathi; imisipha ngalinye uphakathi peremiziem yangaphandle. Muscle kunye zomzimba nokuqina iyaqhubeka omnye komnye kunye ezihambelanayo. Umsipha lonke livalelwe esingxotyeni salo ekuthiwa ifascia. lwamathambo kuquka izihlunu, nganye oludityaniswe imizwa kunye nempahla yegazi kwaye elangena kuzo.

Izihlunu ukugcina intsalela umzimba, ukuba enze intshukumo esithubeni kwaye intshukumo ebalulekileyo onke amalungu omzimba.

imisipha Smooth ibekwe Imithambo yegazi kunye nezibilini. Ubude yale hlobo zihlunu yi 0.02-0.2 mm. Bona, ndayihluthwa striation, isimo sabo ufana yokuluka. Iiseli kwemisipha smooth ezi okweqanda embindini core.

imisipha Smooth ukunceda zothutho siqulethwe kwi amalungu ezibuhlazarha (ukutya emathunjini, umzekelo). Bona inxaxheba ummiselo yengcinezelo, ukwanda kunye yindibanisela umfundi, ezinye iintshukumo zomzimba. Imisipha smooth luvo yawo uxanduva.

inkqubo Musculoskeletal kuquka imisipha intliziyo, nto leyo ifumaneka kuphela eludongeni entliziyweni. Yena ngokuqhubekayo kunciphise esaphila, ngokubonelela ukuhamba kwegazi ngokusebenzisa kwimikhumbi lokondla izinto izicwili eziyimfuneko kunye namaziko.

Iintungu-skeletal system

Umzimba womntu iqulathe malunga 400 izihlunu striated, leyo kuthiwa ziyancipha phantsi kolawulo kwenkqubo luvo.

Iintungu-skeletal system iquka izihlunu, amathambo, imisipha, amalunga, nemisipha kunye intlala ezenza phantse 75% kobunzima bomzimba. Le nkqubo inika umzimba womntu imilo ethile, likuvumela ukuba ume, uhambe. Amathambo ukuya Amalungu nezihlunu lisebenza amathambo, oko ukwakhusela amalungu abalulekileyo umonakalo. Amathambo angemi izimbiwa ezifana phosphorus kunye calcium. Embindini ithambo bubonakaliswe ngayo umongo wethambo, abathatha inxaxheba ekubunjweni iiseli (iiseli ezibomvu, iiseli ezimhlophe zegazi).

Xa ukwenzakala kunye nezifo nayiphi na inxalenye yenkqubo musculoskeletal yi statics waphazamiseka Dynamics yonke eziphilayo. Ukongeza, ukuba unesifo yonke le nkqubo musculoskeletal, enyama yangaphakathi, kakhulu, siyeke isebenze ngendlela efanelekileyo. Ngokomzekelo, xa kuphungulwe omnye imilenze na ngomqolo egosogoso, nto leyo ebangela deformation esifubeni sakho, njengesiphumo - baphathwa amalungu kwegazi nokuphefumla.
