Tsandanyama vaikudzwa wamativi murume: mamiriro uye mashandiro

Upper nemakumbo vari chinokosha chokushandisa. Nemhaka zvavo pamberi, vanhu vane mukana kuita zvakasiyana-siyana kufamba uye zviito.

Anatomy rokumusoro kumugumo

The sezvamunoita mamiriro unotora:

• Leather.
• Tsandanyama.
• Bone marangwanda.
• tsinga.
• Mwanda.

Ndiyo anatomi rokumusoro richiripo. Kurudyi uye rworuboshwe zvakasiyana mumwe. inosiyana uye Zvekare zvimiro zvemhashu zvakaita brushes Somuenzaniso. Kuruboshwe mupfupi kurudyi kusvika hafu sendimita. Form, vane okumusoro nemakumbo, zvichienderana basa, zera, kuti munhui. Zvakafanana rinokosha zvinonyatsorehwa utano. Sechivako yokumusoro muzvidimbu rinotsanangurwa zvinangwa zvayo. Uyewo nokuda peculiarities ari tishu mamiriro. Upper kumugumo basa zvikuru yakakura. Kuburikidza nezviito zvavo vanhu vanogona kunzwisisa zvinhu, kunyora, nhengo dzomuviri, uye zvichingodaro. Next, funga chii chinoumba tsandanyama vaikudzwa wamativi.

musculature anatomi

Fibers akakamurwa mhando mbiri. Boka rokutanga kunosanganisira tsandanyama pakati bandauko bhanhire, wechipiri - akasununguka chikamu. Kupatsanura rinoitwa zvichienderana zvaunoda uye nzvimbo (pakupera tafura nyaya zvicharangarirwa). Tsandanyama vaikudzwa wamativi iri pamapfudzi bhanhire rakakamurwa deltoid, supra- uye infraspinatus, zviduku, kumativi, uye subscapularis faibha. Sechivako pamafudzi bhanhire zvinosanganisira musculature ruoko, pamafudzi uye honokono.

Large kumativi faibha

Vane elongated sandara chimiro. Tanga kubva rwemberi pasi pakona pamusoro chipande. Tsandanyama izvi okumusoro Mbabvu vari akatarira murwi diki iri humerus (the penyika). Rear The hotera adjoins dzakafara fibers shure. Teres chikuru tsandanyama okumusoro wamativi apo yokuderedza achizvuzvurudza papfudzi rake, kumudzinga mukati. Somugumisiro, ruoko akadzokera muviri.

ari deltoid fibers

Ivo dzinoturwa muchimiro netriangle. Under yepazasi chikamu yokumusoro muzvidimbu tsandanyama dziri subdeltoid muhomwe. Fibers zvinenge zvakazara papfudzi muhudyu zvachose uye pamafudzi tsandanyama munharaunda. The deltoid zvinosanganisira matanda makuru kuti wekuita pamusoro. Vari yakakamurwa maererano mabasa. Rear rakatama rwake shure, mberi - mberi. Tangai fibers kubva chipande akabatana (lateral magumo) uye chikamu clavicle. kugadzira mugove - iri deltoid tuberosity yacho humerus. The deltoid tsandanyama rokumusoro muzvidimbu yabviswa mapendekete outwards asati nokutora chinjikira chinzvimbo.

Small denderedzwa fibers

Idzowo ane oblong tenderera tsandanyama. Nechemberi rinosanganisira deltoid fibers, kumashure - guru denderedzwa. Kutanga kubva chipande ruoko, zvishoma pazasi infraspinatus fibers riri pedyo kwayo pamusoro penyika. Chidimbu wanamatira nzvimbo pachikomo yacho humerus vadyi Kamudzira (kurutivi rwemberi mugove waro). Muscle inodzora outwards ruoko, Anodzokera Shure uye kuminyuka mekamudzira aka.

supraspinatus fibers

Zvinoumba mativi shaped tsandanyama. Riri mune supraspinatus fossa pasi trapezoidal chidimbu. Kugadzira nzvimbo musana papfudzi kwemajoini Kamudzira uye nhandare pamusoro guru murwi mapfupa. Muscle kunotangira pemvura Makomba. Nengano rutapudzo pamusoro faibha rinobuda vakakwevera mafudzi kwemajoini Kamudzira, izvo kunotadzisa jamming.

subscapularis faibha

Vari inoumbwa mativi yakafara sandara tsandanyama. Fibers vari yakarongwa Collet fossa. On panzvimbo pane tendinous kuda bhegi. Subscapularis tsandanyama anotanga richiita, uye inoguma - mune murwi duku iri humerus uye pamberi mekamudzira aka. Akaroromesawo bandauko rotates mukati fibers.

infraspinatus faibha

Zvinoumba sandara mativi chimiro tsandanyama. Zvinowanikwa chidimbu ari infraspinatus fossa. Tanga fibers riri navaivanda pamadziro uye Collet. Zvinonzi wakaiswa kuti Kamudzira pamusoro fudzi muhudyu uye yepakati pasi pamusoro mukuru tuberosity mapfupa, pasi riri podsuhozhilnaya bhegi. Nokuveza, fudzi tsandanyama anotendeuka outwards, anobvumira kutora ruoko, kuminyuka vagari Kamudzira.

papfudzi tsandanyama

Rakakamurwa mapoka maviri. Front anoita flexion uye uyewo anoratidza shure pamafudzi uye honokono. Boka rokutanga rinosanganisira biceps, pamafudzi tsandanyama, uye muromo. Nemamiriro rechipiri chidimbu zvinosanganisira triceps uye kugokora tsandanyama vaikudzwa wamativi murume.

miviri misoro fibers

Zvinoumba chokurukisa-woita tsandanyama. In ayo mamiriro pane misoro miviri: pfupi, achiita vachikanda maoko uye refu, generating zvinoisa. Ekupedzisira kunotangira kubva epiarticular tubercle mashizha. Short musoro runoita kubva coracoid. In nzvimbo maererano yavo aumbwa mudumbu. Zvinonzi vasiyana ano pamusoro nharaunda. vamwe vane fibrous mitundu vari medial negwara. Vanoumba bwendefa rikurumidze - the fascia. Next, ruchapinda muruoko brachial fascia. Zvinangwa biceps vari zvayaitenderera paguyo panze uye flexing pakati honokono panguva kugokora.

muromo faibha

Zvinoumba sandarara tsandanyama. It rinosanganisira musoro pfupi pamusoro biceps chidimbu. Beaked tsandanyama vaikudzwa wamativi munhu rinotanga pamusoro kupfuura madzinde chete zita rikurumidze. Fibers zvakabatanidzwa pazasi pakati medial chikamu humerus. Nokuda reductions kumutswa mafudzi, maoko kuti midline.

papfudzi faibha

Ivo akaumba yakafarikana fusiform tsandanyama. Kutanga kwayo yakabudikira kumberi dzokunze fudzi mapfupa pemvura. Kutara achaendeswa ayo tubercle uye Kamudzira pakati kugokora rwakashodoka. Fibers vari zvakazara pazasi pafudzi mugove (pamberi divi) nokuda biceps tsandanyama.

ulnar chidimbu

tsandanyama ichi ane pyramidal chimiro. rakatangwa - the lateral epicondyle pamusoro pamafudzi mapfupa. Fibers vasiyana rwemberi chikamu muviri ari ulna uye zvakafanana muitiro. Kuderedza, tsandanyama kunosvika honokono. Rinotaurawo rinoronga kunonoka iri Kamudzira pakati kugokora rwakashodoka.

triceps faibha

Zvinoumba refu ruoko. Inoitwa 3 misoro: medial, lateral uye refu. Kutanga okupedzisira - subarticular scapular murwi. Lateral musoro paunobuda kubva posterolateral chikamu pamafudzi mapfupa, medial - kubva kumashure pamusoro. Zvinhu zviri chokuita chokurukisa serin'i dumbu. Zvino unopinda mudzira. Kutara mudumbu chinoitwa kuti mekamudzira aka uye Scion kugokora. Tiine rutapudzo kuti faibha unbent honokono, yakadzurwa shure ruoko uye ruoko kuti muviri. Muscle iri olecranon kusvika chipande.

internet honokono

Zvinoumba mapoka maviri tsandanyama: mberi neshure. In nomumwe wavo pane nokusanzwira kwakadzama pamusoro rukoko. Enda neokupedzisira pamberi boka rinosanganisira flexor (ulna uye nharaunda) uye minwe, brachioradialis chidimbu, pronator teres tsandanyama. sezvo refu Palms tsandanyama ndowenyika dhipatimendi. Gobvu rukoko rine mativi pronator, flexors: rurefu thumbs uye munwe zvakadzama. To zvomene tsandanyama ari kumashure boka zvinosanganisira kugokora, pfupi uye refu TOUR extensor chiningoningo, thumbs uye munwe shoma. Gobvu rukoko wedhipatimendi kupa instep, tsandanyama, iyo extensor uye abductor thumbs (pfupi uye refu), extensor indekisi chigunwe.

musculature mumakwenzi

Tsandanyama zvakarongwa pamusoro Palms pamusoro. Fibers vari rakakamurwa akawanda mapoka: Zvichakadaro, medial, lateral. Seri pose bhurasho vari chete zita interosseous tsandanyama. Mugore lateral boka fibers varipo, kwokururamisa kwebasa thumbs: achisiyanisa kuti mugumisiro, flexors zvinoyerera. The medial zvaisanganisira palmaris brevis tsandanyama uye tsandanyama duku nomunwe. Ekupedzisira anosanganisira pfupi flexor ari kutungamirira uye nzira yokubudisa fibers. Pakati boka chipo vermicular, Palms uye dorsal interosseous okunze.
