Ithole liyingxenye yemilenze ewugqinsi kakhulu emzimbeni womuntu. Impendulo yombuzo othi yini inkonyane futhi iphi ithole ifika ngemva kwendawo yethanga nangaphambi kwendawo yeqakala. Indawo yethole iqukethe kokubili izicubu zemisipha namafutha. Kukhona nemizwa eminingi nemikhumbi ezungeze le ndawo.
Likuphi Ithole?
Indawo yethole iyindawo ebalulekile emzimbeni womuntu ukusiza uhlelo lokujikeleza kwegazi. Imithambo yegazi isebenza kule ndawo ukusiza igazi libuyele enhliziyweni. Ngesikhathi esifanayo, imisipha yethole iphinde isize abantu ukunyakaza. Ihlukaniswe kabili: ithole eliphezulu neliphansi.
Imisipha Yendawo Yenkonyane
Indawo yethole iqukethe imisipha emibili emikhulu, i-gastrocnemius ne-soleus. Le misipha yizingxenye ezivelele kakhulu zendawo yethole. (Ngolwazi oluningiliziwe mayelana ne-leg anatomy, bheka kusukela kulesi sihloko ungafinyelela.)
I-Gastrocnemius Muscle
I-gastrocnemius muscle itholakala engxenyeni engenhla yendawo yethole. Lo msipha usiza abantu ukuthi banyakaze ngokunyathela phansi. Lo msipha usebenza kakhulu lapho ugqoke izithende eziphakeme noma ukhuphuka izitebhisi.
umsipha we-soleus
I-soleus muscle itholakala engxenyeni engezansi yendawo yethole. Lo msipha usiza abantu ukuthi bame futhi bahambe. Lo msipha usebenza kakhulu uma ugqoke izithende eziphakeme.
Amafutha Endawo Yamathole
Indawo yethole iqukethe izicubu ezinamafutha. Lesi sicubu esinamafutha sinqwabelana kakhulu kwabanye abantu. Lesi simo ngokuvamile sibangelwa izizathu zofuzo, futhi ungakwazi ukuqinisa indawo yakho yethole ngokudla nokuzivocavoca.
Izinkinga Zendawo Yenkonyane
Abanye abantu bangase babe nezinkinga zendawo yamathole. Lezi zinkinga zingase zenzeke ngendlela yobuhlungu, ukuvuvukala noma i-cramping endaweni yethole. Izinkinga ezinjalo endaweni yamathole ngokuvamile zibangelwa ukulimala kwezemidlalo noma ukuvivinya umzimba ngokweqile.
Ukuzivocavoca endaweni Yethole
Indawo yethole isetshenziselwa izivivinyo eziningi ezahlukene. Ukuzivocavoca endaweni yamathole kusiza abantu ukuqinisa amathole futhi kwandise ukuguquguquka kwawo.
Ukuzivocavoca Kwenkonyane
ukuzivocavoca itholeingenye yezivivinyo ezivame ukusetshenziswa kakhulu ukuqinisa imisipha yethole. Lo msebenzi uwumsebenzi wokuphakamisa isithende owenziwa ngenkathi umile.
Ukwelula Inkonyane
Ukwelula inkonyane kubalulekile ukugcina imisipha endaweni yethole iguquguquka. Lo msebenzi ungenziwa kunoma iyiphi indawo lapho ungakwazi ukwelula amathole akho.
Amazing Machine Amathole
Ukuzivocavoca komshini wenkonyane kuyithuluzi elikhethekile lokuqina elenzelwe ukuqinisa inkonyane. Lo mshini uwumsebenzi owenziwa abantu abancike ezinyaweni zabo. Umshini usebenza imisipha yethole ngokuhambisa izinyawo phezulu naphansi.
Ucwaningo ngeSifunda Sethole
Ucwaningo ngendawo yamathole luhlobene nempilo nokusebenza kwale ndawo. Nazi ezinye izibonelo zocwaningo olwenziwe endaweni yamathole:
Olunye ucwaningo lwathola ukuthi uhlelo lokuzivocavoca lokukhama nokukhulula amathole lwandise ukujikeleza endaweni yethole leziguli ezinokwehluleka kwe-venous okungapheli.

Kwesinye isifundo, umphumela wezinhlelo ezihlukene zokuzivocavoca ngejubane lokufinyela namandla emisipha yethole wahlolwa. Ocwaningweni, kwanqunywa ukuthi ukuzivocavoca okwenziwa ngokushintsha i-angle ye-ankle namadolo kwaba nemiphumela emihle ngesivinini sokufinyela namandla emisipha yethole.

Ucwaningo lwesithathu lwahlola ukuthi imisipha yethole ishintsha kanjani ngokuya ngeminyaka. Ucwaningo lwathola ukuthi ubukhulu bemisipha yethole lehla futhi amandla emisipha ehla kubantu asebekhulile.
