Anatomia: humerus. Ka 'ole o ka humerus

E hana i ka mana o ke kākoʻo, ka hele a me ka hoomalu i loko o mākou kino i ka'ōnaehana i nā iwi, nāʻiʻo, tendons a me ligaments. A pau kona māhele ulu, a hoʻomōhala i ka pili alu like 'ana. Lākou me nā hale a me ka waiwai i aʻo 'epekema'anatomia. Ke humerus He mahele o ka noa maluna lala, a me nā iwi o ka forearm a me ka hoaka o ka lala kaei - clavicle a me ka scapula - 'oi aku ka Ka Uluwehi O Ke ÿano neʻe o ka lima kanaka. Ma keia pepa, i kumu hoohalike no ka humerus, ua hoʻopaʻa haʻawina ma au mamuli o ka loina o ka hana o ka musculoskeletal'ōnaehana, a loaʻa mai ia pehea ua pili i ka 'ole o ka mana hoʻokō.

Hiʻona omo iwi

Triangular a paukūʻolokaʻa shape mea ano no ka eiiiiiaiou o ka iwi - iwi loa ia i kūlana hehee wale e like me epiphysis (iwi kihi a) a me kona kino (diaphysis). Ekolu papa - ka periosteum, ka iwi ia iho a me ka endoost - i kekahi hapa o ka diaphysis o ka humerus. noa luna lala'anatomia ua manawa ma mull pono? anoee. Ua ua ike i na epiphyses hoʻohui pū cancellous iwi, akā, ke kikowaena Oihana poe lamellae. Ka mea, nāna i hana i ka olelo hoopomaikai mea. Kēiaʻano i lōʻihi omo iwi: i ka'ūhā mua, kuʻekuʻe aku, hip-. Anatomia o ka humerus, a ua hoakaka ia ma lalo o ka Hawaii photo Hōʻike i kona helehelena kahi momona a küpono i ke kahua o ka hui ana o ka hoʻoneʻe kāʻei me nā iwi o nā lunaʻaoʻao, a me ka forearm.

Pehea nō nā iwi lōʻihi

Ma embryonic kūpono 'ana o ke humerus me ka iwi a pau ua hana ia mai ka waena germ, ahu iho - mesoderm. I ka hoʻomaka o ka pule elima o hāpai keiki, ka fetus i mesenchymal Hoʻohana kapa i ka lepe puke. Ko lakou ulu ana ma ka lōʻihi, a lawe i ke ano o ke omo iwi o ka'ūhā mua, a ossification mau ma hope o ka hanau ana. Ma luna o ka humerus ua uhiia me ka periosteum. Kēia lahilahi iwi oia hoi o connective'aʻaʻa, a me he lala la pukapuka o na moku koko a me nā aʻalolo a hāʻule pahū wale i e ka maoli iwi a me ka hoolako kona mana a me ka innervation. Ua Ua Aia ma ka holoʻokoʻa loa o na iwi omo a me kona mauʻano i ka ahu iho la mua o ka diaphysis. I hoʻokumu 'ia' epekema'anatomia, humerus, uhi me ka periosteum he laholio puluniu kumuʻiʻo - collagen, e like me kūikawā keena kapaia osteoblasts a me osteoclasts. Ka mea, i Hoʻohui 'puni ka Central Haversian Canal. Me ka elemakule, oia ua piha me ka lenalena iwi ka lolo.

Meaning epiphysis o nā iwi loa

I ka pau ana o na iwi omo o ka'ūhā mua i kapaia ka epiphysis komo 'ulaʻula iwi ka lolo a me ka komo o ka naele ia waiwai. Kona keena paka koko keena - ulaula koko keena a me platelets. i uhi Epiphyses me periosteum, i pokou papa a me nā kaula i kapa trabeculae. Ka mea, i hoʻonohonoho i ka huina i kekahi i kekahi, a hoolilo i ka pahale kāna mau 'ōlelo i loko o ka palapala o ka cavities Systems, a piha hematopoietic'aʻaʻa. Pehea e hoakaka i ka'anatomia, me ka 'ole o ka humerus iwi i loko o na ami o ka ia me he Oopalau la a me na iwi o ka forearmʻano luna'. Ke articular ili o ka humerus i proximal a me ka distal welau. Iwi poʻo i ka convex ili kapa komo iā ia me ka hyaline cartilage, a komo aku la iloko o ka lua o ka maka. Special cartilage ho okumu scapular kaumaha - articular lehelehe - lawelawe 'ana me ka kŰia absorber, e hoopalupalu ana i ka hahau, a concussions i'ūhā mua o ka neʻeʻana. I ka mea hōʻikeʻikeʻuʻuku o ka'ūhā mua hui me kekahiʻaoʻao pili i ka huhui, a me ka mea 'ē aʻe - a hiki i ke poo o ka humerus, e palemo ai i kona'ā'ī. Ua stabilizes i ka pilina o ka'ūhā mua kaei a me ka hoaka o ka lala noa.

Hiʻona o ka'ūhā mua a me ka kuʻekuʻe aku ami

E like me hoʻokumuʻia e ke kanaka'anatomia, ka humerus mea he hapa o ole wale ka spherical poʻohiwi hui, akā, kekahi - o ka luna 'kuʻekuʻe aku. It E e hoʻomaopopo i ka'ūhā mua ami o ka hapanui lawe lima i loko o ke kanaka kino. He mea maopopo, no ka mea, o ka lima o ka papa hana o ka hana ana, a me kona ka hoʻoneʻe ua pili me ka hoʻololiʻana i ka hele pololei ae iluna, a hookuu i komo i loko o ka neʻeʻana.

Ke kuʻekuʻe aku ke ami hoi ua haku o ekolu hookaawale i huiʻia pili, he pono ole articular mea hōʻikeʻikeʻuʻuku. Distal humerus hoʻohuiʻia i ka ulna, ho okumu i ginglymoid ami. Ka poʻe condyle o humerus poo komo i ka lua o ka proximal hope o ke kahahńnai, ho okumu i brachioradialis hoʻoneʻe pilina.
