Poohiwi nāʻiʻo, forearms a me ka'ūhā mua kaei

Poohiwi kaei ninoieo o ekolu iwi: ka clavicle, scapula, humerus iwi (iwi o ke keena lima), e like me ka pōmaikaʻi me nāʻiʻo, ligaments a me tendons. Poʻohiwi ami i hoʻoneʻe ami ma waena o ka'ūhā mua iwi. Nāʻiʻo a me ami i ka'ūhā mua ae ia e hoʻoneʻe i loko o ka hoʻoholo ma mua huahelu o ka noi. ʻO nāʻiʻo o ka'ūhā mua, a me ka'ūhā mua kaei, he kuleana no ka holo ana o ka scapula, humerus, a me ka clavicle. Eia kekahi, ua hoʻokino mau nāʻiʻo poohiwi, me ka'ūhā mua hui a me ka axillae (armpits). No ka laʻana, ua hoʻokōʻia ka mea contour o ka'ūhā mua ami ua hana deltoid Muscle. Anatomically, ka mea ho he okoa kau o ka olona, nona ka hana ua papa hoʻolaukahi ma ka Central ko mākou hopohopo nenoaiu.

Kanaka poohiwi - o ka luna aʻe o ka lima a me na nāʻiʻo a me nā iwi, manao ma waena o ka'ūhā mua a me ka kuʻekuʻe aku ami. Ka luna kali ana o ka'ūhā mua - ka laina transverse o ka lalo kae o ka pectoralis nui, teres nui Muscle a me ka pālahalaha hoʻi nāʻiʻo. I ka lalo kali waiho ma luna (2 transverse manamana lima) o na condyles o ka humerus. Poʻohiwi nāʻiʻo i ka hooponopono ia ma luna o ka mua a me ka hope surfaces o ka humerus. Ka mua pūʻulu o nāʻiʻo kapaia na biceps (ma Roma - musculus biceps brachii) a biceps. Posterior pūʻulu nāʻiʻo - triceps (ma Roma - musculus triceps brachii) a me triceps.

Resilient a me ka laholio'aʻaʻa (skeletal, a me ka mea, ua kapaʻia nō hoʻi striated) e hana i ka'ūhā mua nāʻiʻo, i ke aloha a hiki i kā lākou hana, e ho'ēmi i nā aʻalolo impulses. No ka mea, no kēia mau waiwai o ka Muscle'aʻaʻa mea he holo o ke kuʻekuʻe aku, a me ka triceps a me biceps i kuleana no kēia mau hana. Eia hou, nā o kēia nāʻiʻo ho oholo i ka kinona o ka'ūhā mua, a hilinaʻi nui ma ke degere o ka momona a me ka Muscle. Ma muli o ka subcutaneous momona i loko o nā keiki a me nā wāhine i Keʻei o ke kanaaho nāʻiʻo a me ka lima mai o ka palapala a kokoke i ka pololei paukūʻolokaʻa. I na kanaka a me muscular poʻohiwi nui ka leo i loko o ka luna ma mua i loko o ka wahi moe ana i ke kuʻekuʻe aku.

Colloquial inoa o na biceps - biceps - ua loko mai o nā Roma'ōlelo: bis, a translates like kaulua, a me ka caput, la me ka manao poo ma ka unuhi. Biceps (mau Muscle laulau) he mau poo, ai pili aku i ka waena o ka'ūhā mua a hiki i ka pau Muscle opu. Ka lōʻihi poo ua pili i ka maka (epiarticular roughness a kāwaha ma) loiloi mua tendon. Pōkole poo i hoomaka, mai ka maka (coracoid kaʻina). Biceps pili i ka luna o ka forearm tendon hopena, i loko o a o ka huina abdomen. O ka papa kuhikuhi hana o keia Muscle mea flexion o ke kuʻekuʻe aku ami o ka lima. Ua Ua innervated ma ka muscular-cutaneous nā aʻalolo.

Colloquial inoa o ka triceps nāʻiʻo - triceps - i hele mai, mai nā Roma olelo, i ka mua o ia (Tri) mea ekolu, a me ka lua o ka (caput), e like me ka ua, ua ho'ākāka 'ia ma luna. 'O kēia ka hola 2/3 lima Muscle he nui Muscle mea a mea kuleana no ka straightening (straightening) lima i ke kuʻekuʻe aku, ke kuʻekuʻe aku ami i ka hopuʻia ka wā forearm a e hoʻohana no ka lole neʻeʻana, e like me ka wā kākau. Ua ninoieo o ekolu laulau o ka Muscle'aʻaʻa i hoʻomaka me ekolu poo (lōʻihi, medial a me ka kīloi paʻewa), a converge pu i loko o hoʻokahi tendon kuʻekuʻe aku. Classically, ka mea, ua manaoio ia a pau ekolu poo o ka triceps Muscle ua innervated ma ka kahahānai nā aʻalolo. Eia naʻe, loaʻa nō ka hopena o nā haʻawina hōʻike i innervation i e kekahi lala o ka axillary nā aʻalolo.

Kanaka forearm o ka hapa o ka lima, i ua aia ma waena o ke kuʻekuʻe aku hui a me ka na pulima oʻu (ai ole iʻikeʻia e like me ka na pulima oʻu). Ke forearm he o nā iwi a me nāʻiʻo (ulnar a me ka kahahānai). Muscle'aʻaʻa ua i hanaʻia o ka eha papa o nāʻiʻo, a nō ka mea mua panel, e like me nā papa o ka hoʻi Muscle pūʻulu. I ka hopena o kā lākou hana o ka neʻeʻana o nā lima (me phalanges) a me na pulima oʻu. I mau, na nāʻiʻo o ka'ūhā mua a me ka forearm i ke ākeaʻano o ka lima ka neʻe 'ana, forearms a me ka lima.
