Izihlunu ngesa-, umsebenzi wazo

izihlunu Gxalaba umbhinqo kukho iqela izihlunu nemilenze. Eyona phakathi kwabo kuba izihlunu: supraspinatus, teres ezincinane, infraspinatus, deltoid, subscapularis, kunye ngeenxa enkulu. Bona kufutshane kwegxalaba, ngaloo ndlela enceda ukuba ahambe. Izihlunu ezi ziyenza nesandla, kwakunye izihlunu zamagxa, nayo izihlunu nemilenze, kodwa sovbodnoy inxalenye - ngesandla. Izihlunu ezi ziyenza njani bohlulwa babe ngamaqela amabini: ngaphambili nangesemva. Iqela ngaphambili luquka umaleko komhlaba, kwaye izaleko ezimbini nezinye enzulu. Amaqela ngesa- izihlunu umaleko phambi kobuso ziquka:

1. Le brachioradialis kwezihlunu, nto leyo zigxunyekwe kwirediyasi, ukuya ekupheleni kwayo distal. Oku kukhokelela ukugoba zengalo kunye kwisihlahla kunceda ukuba athathe isikhundla eliphakathi phakathi pronation kunye supination.

2. pronator ngeenxa zonke, nto leyo zigxunyekwe kwirediyasi, ukuba wesithathu ephakathi, kwaye idlala indima egoso-goso indlela yengalo.

3. Lo msebe flexor carpi eqhotyoshelweyo encotsheni ithambo yesibini metacarpal. It ilawula izandla isongwe ngenxalenye proniruet yayo.

4. flexor carpi ulnar ezibandakanya iintloko ezimbini - yokuqala neyesibini. Ulawula yokukhwabusha nezizisa brush.

5. Muscle palmar elide, ukuthatha inxaxheba Ukugoba abahluza ibhrashi palmar aponeurosis.

6. flexor digital ikhe flexes on-II V iminwe yokuhlasela eliphakathi kwaye ithatha inxaxheba egoso le brush.

Izihlunu ngesa- emalunga umaleko enzulu iqela ngaphambili zibandakanya:

1. Umnwe flexor elide enkulu, nto leyo ethatha inxaxheba egoso le ibrashi kwakhona flexes indlela yokuhlasela distal abazali.

2. flexor enzulu digital leyo egobile kunye yokuhlasela distal kwi iminwe-II V, kwaye ngokupheleleyo ibrashi.

3. square pronator, zengalo proniruet.

Izihlunu ngesa- Iqela diff kufuneka maleko ezimbini - nzulu kunye nzulu. maleko Deep iqela yelo ngasemva luquka:

1. Le instep, nto leyo ibekwe ngaphezu izihlunu and zengalo supiniruet.

2. Ubude esihlunwini, elabela ibhrashi umnwe kunye ibhrashi enkulu ngokupheleleyo.

3. extensor uzwane elifutshane ezinkulu ibhrashi eqhotyoshelweyo kwisiseko yokuhlasela proximal ze ubhontsi. Yena ngomnwe wakhe asusa ngebrashi enkulu, yaye usinika yokuhlasela proximal.

4. extensor iinzwane elide kwelinye icala, eqhotyoshelwe kwisiseko yokuhlasela distal ze ubhontsi. Oku kukhokelela eqondisa ukuba iminwe enkulu inxalenye kuyisusa.

5. isalathiso digitorum extensor, ligxile yokuhlasela proximal ye umnwe kwicala umva. Yena unbend, ngokulandelelana, umnwe.

Umaleko Umphezulu ngoweqela bakhulise luquka:

1. extensor carpi iphiramidi ebonisa unxibelelwano elide, zigxunyekwe encotsheni ithambo yesibini metacarpal kwicala umva. Yena impela, bawela flex ngesa- kunye kwisihlahla ukugoba kunye beam ukhipha ibrashi uyamthatha.

2. extensor carpi umqadi elifutshane eziqhotyoshelwe phezulu ithambo lesithathu metacarpal kwicala emva ngokuba ibrashi eqondisa.

3. izihlunu extensor digitorum imele esiswini, bedlula imisipha emine yokuqala, leyo ke yona similise imicu eqine, zigxunyekwe esisekweni yokuhlasela distal kunye ophakathi kwi iminwe II-V. Iqhuba umsebenzi lolwandiso kunye iminwe nesandla.

4. extensor ngomnwe encinane, lifumene ukuya yokuhlasela esezantsi oluphakathi kunye distal ukuya V umnwe. Nguye yedwa usinika Ucikicane.

5. extensor carpi ulnar, abebalwa ekuqaleni ithambo yesihlanu metacarpal. Esolula sosana kunye ikhokelela naye. Ngenxa zonke izihlunu ngasentla, kungenzeka intshukumo kwi amalungu izihlahla kunye engqinibeni, kwakunye kwamalunga neminwe nesandla.
