The mkono minofu, ntchito zawo

Phewa lamba minofu ndi gulu la minofu ya nthambi chapamwamba. Ina mwa iwo a minofu: supraspinatus, teres zazing'ono, infraspinatus, deltoid, subscapularis, ndi kuzungulira lalikulu. Iwo anapeza olowa phewa, kuti akuthandiza yakuchoka. Minofu ya mkono ndi dzanja, komanso minofu phewa, alinso minofu ya nthambi chapamwamba, koma sovbodnoy gawo - dzanja. Minofu ya mkono ali m'magulu awiri: kutsogolo ndi kumbuyo. Gulu kutsogolo zikuphatikizapo pamwamba wosanjikiza, ndi zigawo ziwiri kwambiri ena. Magulu mkono minofu wosanjikiza kutsogolo padziko monga:

1. The minofu brachioradialis, omwe chili kwa utali wozungulira, kuti kutha wapotalikira. Zimadzetsa ku kupinda wa mkono ndi dzanja amathandiza udindo wapakatikati pakati pronation ndi supination.

2. wozungulira pronator, omwe chili kwa utali wozungulira, kuti lachitatu yapakati ndi nawo mu wakuba wa mkono ndi.

3. flexor carpi mtengo Ufumuyo pamwamba pa wachiwiri metacarpal fupa. Kapoloyu amasamalira manja apangidwe ndi mbali ya proniruet ake.

4. flexor carpi ulnar wopangidwa mwa mitu iwiri - yoyamba ndi yachiwiri. Iye akulamulira kungomanga ndi kubweretsa burashi lapansi.

5. Minofu palmar yaitali, kuchita nawo kupinda ndi Yosefera burashi palmar aponeurosis.

6. zachiphamaso digito flexor flexes pa II-V zala phalanx sing'anga komanso watenga mbali mu wakuba wa burashi lapansi.

The mkono minofu zokhudza wosanjikiza zakuya za gulu kutsogolo monga:

1. yaitali chala flexor zikuluzikulu, zimene watenga mbali mu wakuba wa burashi komanso flexes ndi phalanx wapotalikira ya chala.

2. kwambiri digito flexor amene anaŵerama ndi wapotalikira phalanx pa zala II-V, ndipo kwathunthu burashi.

3. pronator lalikulu, proniruet mkono.

The mkono minofu kumbuyo gulu ndi zigawo ziwiri - kwambiri ndi osaya. Nato wosanjikiza wachokera kumbuyo gulu zikuphatikizapo:

1. instep, limene lili pamwambapa minofu kungotengeka ndi supiniruet mkono.

2. The kutalika kwa minofu, amene anapereka burashi chala ndi burashi lalikulu kwathunthu.

3. extensor lalifupi chachikulu chala pa burashi Ufumuyo m'munsi mwa phalanx proximal ya chala choyamba. Iye ndi chala chake pa amachotsa chachikulu burashi, ndipo akuwatsimikizira phalanx proximal.

4. extensor yaitali zala pa dzanja, iye Ufumuyo m'munsi mwa phalanx wapotalikira ya chala choyamba. Zimadzetsa ku ataweramuka zala lalikulu ndi pang'ono amachotsa izo.

5. extensor digitorum index, kupenyetsetsa phalanx proximal wa index chala pa mbali kumbuyo. Iye unbend, motero, zosonyezera chala.

Pamwamba wosanjikiza a gulu kumbuyo zikuphatikizapo:

1. extensor carpi zozungulira yaitali, atathana pamwamba pa wachiwiri metacarpal fupa ku mbali kumbuyo. Iye ali ndithu pang'ono Flex mkono ndi dzanja flexors ndi mtengo chimafikira burashi ndi amugwila.

2. extensor carpi lalifupi mtengo Ufumuyo pamwamba wachitatu metacarpal fupa ku mbali mmbuyo ndi kutumikira monga burashi ataweramuka.

3. extensor digitorum minofu akuimira pamimba, kudutsa woyamba tendons anayi, amene nawonso lidzasinthidwa tendon kwamakokedwe, lokhazikika kwa m'munsi mwa phalanx wapotalikira ndi pakati pa zala II-V. Iwo amachita ntchito ya extension zala ndi dzanja.

4. extensor ya chala chaching'ono, wotetezedwa kwa pansi pakati phalanx ndi wapotalikira kuti V chala. Iye yekha chimafikira chala chaching'ono.

5. extensor carpi ulnar opezeka pa chiyambi cha chachisanu metacarpal fupa. Iye akutambasula dzanja ndi kumabweretsa ake. Zikomo onse minofu pamwamba, n'zotheka kuyenda mu mafupa a polumikizira ndi m'zigongono, komanso mfundo za zala ndi dzanja.
