The ruoko chidimbu: anatomi

Upper gumbo murume akaita basa rinokosha mune shanduka inotungamirwa ake ave rudzi. Munyaya ino tichakurukura chikamu munhu nemhuka maoko, kunyanya nechivako dzavo uye inoshanda.

Zvinonyatsorehwa hurongwa maumbirwo rokumusoro richiripo

Yokumusoro kumugumo ine zvikamu zviviri. Wokutanga anoti bhandi zvinosanganisira clavicle uye scapula. marangwanda rusununguko Mbabvu - rokuti wechipiri wanamatira kwavari. Inoitwa mumwe unpaired humerus. Iye slidably chokuita kuti ulnar uye TOUR Anoumba honokono. Zvinotevera zvikamu ruoko - bhurasho ichi. Zvinosanganisira mapfupa carpal, metacarpal uye phalanges.

Yokumusoro Chikamu ruoko

Sechivako dhipatimendi ichi kunosanganisira aiwanzopiwa wokushanda clavicle uye scapula. mapfupa aya rokumusoro muzvidimbu bhanhire zvinopa Usazviomesera kubatana zviri hunde marangwanda vakasununguka ruoko. Clavicle pamusoro ruoko rumwe zvakabatana flat breastbone uye panorumwe - pamwe vanekuva. pfupa Izvi wandei curved uye tsime palpable yose. Its chikuru dzichipfekeka nzi muviri nzvimbo fudzi muhudyu nechokure kubva pachipfuva. Izvi zvinowedzera zvikuru kuwanda inofamba okumusoro maoko nemakumbo.

Rezasi Chikamu ruoko

Bone vakasununguka kumugumo skeletal movably kwakabatana uye kuumba akawanda majoini: sternoclavicular, mafudzi, kugokora, radiocarpal. Zvivako zvose izvi vane chete STRUCTURAL urongwa. Chero vagari musoro mumwe mapfupa chikamu kudzamisa mamwe. To vagari zviso havasi kuona simba kukweshera, avo rinotaura hyaline shwashwa. Mumwe Chimiro kwakadaro kuri mekamudzira aka, kuti zviri kurerekera nemarunda uye tsandanyama.

Zvimwe zvikamu ruoko rwomunhu vane maitiro avo. Somuenzaniso, napagumwe roruoko ndiyo ichingoshora vose. Izvi chokuita munhu anogona nokungwaririra kushanda.

Nemamiriro maoko ose mhuka zvakafanana mhando Chord. Inoitwa mumapoka matatu: fudzi, honokono uye ruoko. unhu hwavo morphological uye kusiyana vari chokuita dzinogarisana mhuka. Saka, muna shiri nokuda kugona kwavo kubhururuka rokumusoro nemakumbo kunge ikava mapapiro. Moles uye shrews kuwana zvokudya zvavo, achiita inofamba muvhu. Naizvozvo, vane zvakawanda kuchera maoko nemakumbo. Vamiririri murayiro zviremwaremwa mhuka chakatorwa kuti kushingaira ndege nokuda pamberi ganda muzvirugu uye elongated minwe. mhuka Hoofed kuwana zita ravo nokuda pamberi anodzivirira horny idzodzo zvavo nemakumbo.

The mashandiro okumusoro Mbabvu

nhengo dzose dzevanhu uye mhuka maoko kutamira nemhaka tsandanyama. Vari vasiyana pfupa pamwe nemarunda. Muscle, zvichiguma muzvidimbu kufamba, kukabatanidzwa mumapoka maviri. Chokutanga richiripo ndeyokubvisa. Somuenzaniso, ari biceps, kana biceps kunokonzera ruoko kuti muviri. Extensors vanoita Ivan Kuchin kushandiswa. Muvanhu, basa iri kuteererwa triceps. Deltoid kuita akatarisana mirayiridzo. fibers dzayo, nechemberi pemvura honokono, ruoko ndeyokubvisa. Uye avo vari iri neizvi divi - nekusiyana.

Ganda maoko mhando akasiyana receptors. Ichi chinokosha nzwisisa idzodzo kuti kubatanidza muviri pamwe zvakatipoteredza. Vanokwanisa kuchinja mu mhando dzakasiyana tsinga mafungiro migumisiro. Zvazvakadaro, mashoko runopiwa akakodzera kumatunhu uropi cortex. Conductive nzira iyi nyaya ndizvo fibers etsinga. Muuropi, mashoko anoongororwa mune neizvi mirayiridzo iri vaipa kune kushanda muviri. Mhando inoverengeka receptors iri paganda maoko. Mechanical kunzwisisa kumanikidzwa uye nokubata. Cold uye kudziya muviri anoona Via thermoreceptors. Asi kupfuura zvose ganda maoko uye minwe inonyatsoziva maonero kurwadziwa. Vari akaumba nociceptors.

Upper Mbabvu nokuda peculiarities yechivako chacho une zvakawanda zvinokosha mabasa. Kukwanisa nendege, kugadzirwa kwezvokudya, kuvaka matumba. Chinonyanya akaoma zvinhu ane ruoko rwomunhu anoita basa rake uye ndiyo hwaro shanduka kuchinja zvakawanda.
