Biceps: Mabasa, mamiriro. The kufamba yokuzvidira dzinotungamirirwa ne biceps?

Movement majoini wamativi rinoitwa anoonga basa tsandanyama iri pamusoro pavo. Zvinosanganisira anokosha fibers akaronga matanda. Muviri womunhu une tsandanyama anenge 400, izvo achifuridzirwa zvinodiwa nechepakati tsinga vanokwanisa kuchinja nzvimbo muviri.

Mhando tsandanyama tishu

Movement hazvibviri pasina kutora chikamu tsandanyama. The zvachose guru rinenge mumuviri zera iri munzvimbo 30-40%. In vana vachangoberekwa, zviri vanenge 20% mune vakwegura - ipfupi kusvikira 25-30%. Asi kana munhu, kunyange zera rukudzo anoramba kushingaira, asi kwetsandanyama isina akaderedzwa, zvazvinosarira nenguva chechetere.

Nyanzvi kuziva akasiyana tsandanyama mapoka zvichienderana nzvimbo yavo, basa, achitungamirirwa fibers. By nzvimbo musiyano wemarudzi aya tsandanyama:

- pemvura (riri pasi ganda);

- yakadzika;

- lateral;

- medial;

- kunze;

- zvemukati.

Maumbirwe nyanzvi kusiyanisa chokurukisa, mativi, mativi, dzeraundi, Ribbon-kufanana tsandanyama. Maererano nenhamba misoro inogona kuva kaviri musoro, triceps uye quadriceps. Zvichienderana kutungamirirwa matanda vava semipenniform, dvuperistymi kana mnogoperistymi.

Uyewo kusiyanisa tsandanyama Rinoshanda. Vamwe vanopa rasgibanie maoko nemakumbo, vamwe - vachikotama. Oga oga rotator-podnimateli, constrictor (sphincter), iyo nzira yokubudisa uye kukonzera netsandanyama.

Somuenzaniso, mashoko brachial biceps tsandanyama chokuita tsandanyama spindly. It wanamatira pfupa, inova mhikuriso, uye matanga maoko pana kugokora.

papfudzi biceps

Biceps tsandanyama ruoko anoreva tsandanyama ari pamberi boka. It iri pamberi humerus. Izvi refu fusiform tsandanyama chine misoro miviri. Mumwe refu, uye wechipiri - pfupi. Vanofamba parutivi, kuenda kubva kumusoro kusvikira pasi. Pachiyero pakati pamafudzi, vari zvakabatanidzwa mudumbu veretenopodobnoy fomu.

The refu Musoro biceps brachii tsandanyama zvinobva muchimiro munhu woita mudzira epiarticular murwi mashizha. Nepano pamafudzi vadyi kubva kumusoro kusvikira pasi. Inside iri rakagumbatirwa mudzira synovial mumuhara. Uye mbudo nzvimbo pamafudzi akasungwa intertubercular muforo. Ikoko zvinonzi yakafukidzwa sinovalnym intertubercular nyinyo.

Short musoro rinobva panzvimbo imwe uye klyukovidno-pamafudzi tsandanyama, kwenzira klyukovidnogo kwacho. Pamwe chete, vari zvakabatanidzwa vari pakati humerus. Saka kuumbwa biceps, iyo yaipiwa neropa kubva axilla, rezasi uye yokumusoro ulnar rubatso, brachial uye TOUR arteries agodzoka.

Panopera kunouya mudzira pamusoro biceps, izvo anoenda nemumakomo chikamu nharaunda. Kuchinja kubva tsandanyama rinenge riri mudzira inopfuura zvakananga pamusoro kugokora vadyi, kana pedo naro. The kuda nguva ndiyo bhegi mudzira dvuglavoluchevaya. Kubva kwayo Anterior-medial divi iri rakafara, mutete batana aponeurosis. Anonzi fascia Pirogov. Front vakafukidza ulnar fovea. Izvi aponeurosis dzakarukwa ari fascia pamusoro honokono.

Treglavaya mhasuro

Pamwe rwemberi pose humerus ndiye tsandanyama kuti zvinopa kuwedzera ruoko panguva kugokora. It ane chokurukisa chimiro. The biceps uye triceps tsandanyama Munokudzwa kwete chete nokuda nzvimbo asiwo chivako. The triceps ane misoro mitatu: refu, medial uye lateral. Wokutanga rinotanga pamusoro murwi subarticular mashizha muchimiro woita gobvu mudzira. Kazhinji hwakabatana kusvikira mudzira pamusoro latissimus dorsi. Muscle mudumbu musoro inopfuura pakati dzeraundi tsandanyama (zviduku) uye asiwo pakati chikamu humerus.

Lateral musoro zvishoma akafukidza deltoid triceps tsandanyama. It rinobva pamusoro seri humerus. Masvinga kwayo kuburuka medially kuitira kuti vakafukidza muforo ari TOUR etsinga.

Medial musoro ndiyo pfupi vatatu akurukurwa. Rinotanga akaunganidzwa tsapo pakati tsandanyama ari seri humerus. Rinokosha lateral chacho akafukidza musoro. Pakati pavo paburi fudzi ndiye TOUR etsinga-tsandanyama gwara.

The pakati chikamu rwemberi pemvura mafudzi, misoro zvose vatatu interconnected uye zvinoumba mudumbu. It rinopera gobvu mudzira, iyo wanamatira rinokosha chirongwa ulna.

Flexion uye kuwedzera pane kugokora yacho honokono zvinopa chete biceps uye triceps tsandanyama. Also anobatanidzwa izvi uye pamafudzi tsandanyama, akadana brachialis.

gumbo tsandanyama

Neshure pose posterior tsandanyama boka ndiyo femur. Anosanganisira maviri misoro, semitendinosus uye semimembranous tsandanyama. Ivo vose vanotanga munzvimbo yacho ischial tuberosity. Vakatanga kufukidza guru gluteal tsandanyama.

Panyaya iyi, kana semitendinosus uye semimembranosus tsandanyama dziri medially, vaviri misoro tora lateral nzvimbo. The femoral biceps akatambanudza yose kureba femur, ine chokurukisa chimiro. Ndiye yakabatana pechidya vastus lateralis tsandanyama. Rusvingo lateral anoumba popliteal fossa femoral biceps. Its basa unogona kuita nokuda chaihwo marongerwo uye fastening mumwe pfupa.

Kuchitanga misoro miviri - refu uye pfupi. Pakutanga wokutanga idzi pfupi gobvu mudzira. Riri pamusoro pemvura sacroiliac nemarunda bugornoy uye ischial tuberosity. The tsandanyama hachisi downwards uye obliquely mune lateral negwara. Chinonyanya magumo zviri vasiyana tibia.

Musoro pfupi pamusoro biceps femoris kunotangira kubva seri pechiso femur. Rezasi kumucheto miromo yayo mupambare mapfupa (tibia).

misoro Vose vari zvakabatanidzwa pamuuyo nzvimbo pakati rezasi uye pakati chikamu femur. Vopinda imwe zvakafanana mudzira. Kuti parinopfuura kubva seri ibvi. Akati mudzira wanamatira kuti fibula (wake musoro) uye chokunze chikamu lateral condyle maringe tibia. Aoma fibers dzayo yakarukwa kupinda fascia tibia.

kushanda biceps

Zvichienderana worudzii basa kunogona kuita tsandanyama, vari rakakamurwa flexors uye extensors. Izvi zvinopesana huripo boka tsandanyama kuti zvinopa kufamba maoko nemakumbo. Huru flexor tsandanyama pamusoro yokumusoro ruoko ndiyo biceps.

izvozvo anoita zvinotevera mabasa:

- anokotama kugokora ruoko;

- achibvumira kwekunze kutenderera bhurasho;

- tisawirirane panguva kugokora ruoko.

Huru flexor yokumusoro gumbo ndiyo biceps femoris.

Rinoshanda rutsoka biceps:

- ekisitenjeni uye adduction yehudyu;

- kuswatura of hunde pashure kurereka;

- vakafugama mabvi ezasi gumbo;

- akashandura kuruvazhe divi rezasi gumbo, akatsivama panguva ibvi;

- abate pachiyero.

Zvinokosha kucherechedza kuti vane biceps nematambudziko, akadai rayo kushaya simba kana mukana wokushandiswa kutungamirira kutsigira marwadzo, mabvi vadyi matambudziko, murombo mamiriro.

Kuwedzera yokumusoro wamativi inopiwa mabasa triceps, riri pedyo humerus. The biceps uye triceps tsandanyama anogona vokudzokera pamwe chete kana poperemeno. The kwebasa makumbo ari ibvi unokurudzira kwakarongeka basa biceps uye quadriceps netsandanyama.

extensor tsoka

The guru tsandanyama mumuviri womunhu ndiye quadriceps. It riri nechemberi yehudyu, uye anopa kukwanisa kutwasanudza rezasi mutezo munharaunda yacho ibvi. Iyewo anokonzera hudyu flexion - rava kusvika chikamu chino gumbo mudumbu.

Quadriceps ine namatanda mana. Mumwe nemumwe wavo mhasuru ane zita rayo. Oga, nyanzvi kusiyanisa zvakananga, paupamhi laterialnuyu, medial uye zvenguva tsandanyama.

Vose vari vasiyana patella. Asi mumwe nomumwe wavo ane yavo zvinhu. Somuenzaniso, mashoko zvakananga anokonzera hudyu flexion uye kuwedzera ibvi rwakashodoka. Asi pakati medial uye lateral kuwedzera zvaidikanwa mhuru.
