Anatomy. yevanhu honokono

Sechivako sechivako rezasi uye yokumusoro ehomwe ndiyo zvakafanana. Kukura muruoko munhu akarega aitsigira. Zvino iye anogona kuita merwa siyana kufamba. Saka, pfupa uye vadyi marongerwo rokumusoro muzvidimbu inoratidza basa ravo sezvo nhengo dzomuviri, kuona akasununguka kufamba. In rusununguko urwu inofamba iri pakutsvaga bvumidzwa mwero rusununguko mapfundo.

Upper gumbo murume rakakamurwa muzvikamu zvitatu: fudzi, honokono uye chiningoningo. Mapfupa vari kubatana nemarunda uye mapfundo nokuumba zviyero, izvo kushanda zvakafanana levers.

The maumbirwo rinosanganisira honokono mapfupa (ulnar uye TOUR), okumusoro cylindrical mapfundo tsandanyama zviri shure uye mberi boka.

The ulna riri medially (pinky divi) TOUR pfupa laterally (parutivi napagumwe roruoko). Vari zvakabatanidzwa pachishandiswa okumusoro cylindrical majoini. kwemajoini zvavanoita anopa rotational kwebasa honokono ura outwards. The mufambo ndiwo maitiro chete nokuda nharaunda. Inofamba (akafanana kufamba nekambasi gumbo) vakapoteredza ulna, iyo inogara mira. Akawira pasi kugokora mapfupa, nharaunda articulates pamwe marangwanda ari chiningoningo.

Human honokono Tsandanyama ane mberi uye neshure mapoka. The mberi kuchibva flexor nomunwe uye ruoko tsandanyama uye kutenderera mukati. In seri boka ndiwo extensors ari nemimwe uye chiningoningo uye tsandanyama, kutenderera outwards.

Zvinofanira kucherechedzwa kuti vose siyana uye kunzwisisa kufamba chokumusoro muzvidimbu zvikamu kushandisa mamwe nyore kufamba mapfundo siyana.

Honokono munhu anogona Vanokunga, tenderera nechomukati kana kunze uye unbent. Kuchiva anobudiswa akapoteredza lateral uye wehunyambiri akabatana mune kugokora. Movement zvinoberekwa mapoka mana dzichipfekeka kuti tsandanyama.

Fambisa flexion muviri: pronator teres tsandanyama chokuita honokono tsandanyama, kutangira kubva humerus (dzomunyika epicondyle), biceps, brachioradialis tsandanyama, pamafudzi tsandanyama.

Motion kurovedza triceps chiwedzerwa. It chikamu papfudzi uye chinosanganisira kugokora tsandanyama, tsandanyama ari honokono, kutangira kubva epicondyle yaiva laterally kune humerus.

Movement (rotation) mukati (pronation) unotakurwa kumativi uye mativi pronator. In ichi chikamu brachioradialis tsandanyama (mu chinopesana pronation nzvimbo).

Movement (rotation) outwards (supination) rakatakurwa honokono kwevanhu tsandanyama-instep uye biceps tsandanyama. Rotational kufambira vakaita pronated nzvimbo (kubva mukati outwards).

Tsandanyama hunoumba yevanhu honokono, uye kupindurawo kufamba ruoko uye chiningoningo.

Vakafugama rinoitwa nharaunda uye ulna chiningoningo flexors, refu Palms tsandanyama, zvachero uye rakadzika flexor digitorum longus. Zvinofanira kucherechedzwa kuti vatatu flexor digitorum kubudisa mawa kufamba.

Wrist anowembura, tenderera nechomukati kana kunze uye unbent. Zvinofanira kucherechedzwa kuti saizvozvo articular mufambo zvishoma. Kusara ndiyo carpometacarpal vadyi yacho thumbs.

Free kufamba okumusoro wamativi ose zvikamu anotsanangurwa nomunyori bvumidzwa mwero rusununguko muna rwakashodoka neimwe. Zvinofanira kucherechedzwa kuti kukura tsandanyama zviri honokono, zvikurukuru, munyaya ruoko uye nomunwe kufamba kunokosha mune kunyatsogadzikana mwana. Saka, vachiri vaduku vanofanira kushanda navo nomunwe kufamba dzinoenderana mwana zera. Zvinonzi kwakaratidza kuti kwakakodzera kukura injini unyanzvi maoko kunodzivisa yematambudziko kukura kutaura midziyo.
