Spinal kaula

Ke spinal kaula i kekahi o na papa o ka CNS (Central ko mākou hopohopo'ōnaehana), ai pili aku i ke kino i ka mea mawaho i hoʻolilo 'ia a me ka pāʻana kona hana. He mahalo i ka Central ko mākou hopohopo'ōnaehana, a me kela nā loko, a nenoai i hooholo ia ma muli o nā loli i ana i loko o ke kaiapuni.

lolo kamaʻilio me nā kino, a me ka lala ma ka hoʻohana 'ana i ka spinal kaula. Ua hanaʻia ka introducer a me ka reflex hana.

Pehea mea a ma ka spinal ke kaula

Ka 'ole o ka' Oihana CNS, kŘpa a mea. Ke spinalʻaha ua hana e poʻo, a keʻokeʻo mea. White mea - he luna 'kahua o nā aʻalolo olona, (myelinated a me unmyelinated), nā aʻalolo a me ke koko moku i marginally hoʻopuniʻia connective'aʻaʻa. Oho lelo kuahene aeea nā aʻalolo kino me keʻano o ka hanaʻana i e ole i ka myelin wahī. E like me ka waenakonu o ka spinalʻaha hele i ke kai a ua hoopihaia me ka cerebrospinal loli. Me ka na nā loko, a lala kona hui pu mau nä olonä, a i wehewehe aku e kupono auaiaea alapine (frequency).

spinal kaula kīnā i ka laula o kekahi kanaka makua kekahi, a me ka hapalua kenimika ma ka lōʻihi -. 45 knm kona awelika kaumaha mea '35

He ka spinal piko o ke kanaka i loko o ka pā makahiki o ka spinal Canal. Nae ko waho, ka mea nana e like me kaʻaha lōʻihi me ka lehulehu lālā. Ka luna hope ona mea i oi palena pili me ka medulla oblongata ma I cervical vertebra, i ka lalo ua aia ma ka pae au-II o ka lumbar vertebrae. He hele aku i loko o ka hopena (spinal) ka pae. Papakaukau haʻawina o ka pae nā hakina o neural'aʻaʻa, akā, i ole ia ia mea he pilina ho okumu. Penetrating i ka dura i loko o ka sacral Canal, spinal ka pae pili ma kona hope.

Aia i ekolu membranes a puni ka spinal kaula. Lilo o ka wahi - pahee (vascular) Average - arachnoid, a mawaho - paa. Mai envelopes i ka iwi Canal i ligaments e malama i ka spinal aho i loko o ke kū kūlana. I ka wa aia ma waena o ka loko a me ka waena wahī hoolako mai cerebrospinal loli.

Pela, ua piha i ka lua o ka spinal Canal ma ka spinal kaula ua noho ai, me ka momoma'aʻaʻa, cerebrospinal loli, lolo membranes a me nā ipu koko.

Lonikū Groove e puʻunaue i ka spinalʻula ma ka akau a me ka haʻalele symmetrical halves.

Ma ka spinal Canal he pōkole mamao nō ke aʻalolo aʻa. Ka mea, i hele mai, mai kela a me keia hapalua, ho okumu i mau lonikū lalani. Ka mea, haʻalele ka vertebral Canal ma nā lua foraminarnye. Ke spinalʻaha Ua wehewehe aku ma ka hai segmental. Hoʻohana i kapa i ka hapa o ka lolo, a haʻalele i ka spinal Canal nā aʻalolo emanating mai o ia mau mea. Kēlā me kēia Hoʻohana innervates kekahi mau wahi o ke kanaka kino.

Aia he elima mau māhele o ka spinal kaula. 'ā'ī hapa ho okumu i ewalu Hoʻohana iwiaoao - heʻumikumamālua Hoʻohana, lumbar - elima sacral - i elima coccygeal - 1-3 Hoʻohana. Hoʻohana o ka cervical innervate i nā mea kaua a me ka'ā'ī, thoracic māhele - i ka pahu a me ka abdomen, lumbar a me ka sacral - wāwae, pelvic nā loko , a perineum. Nā aʻalolo aʻa e holo ana ma lalo o ka 'ilikai o ka spinal kaula a hāʻule pahū wale innervate ka haahaa hapalua o ke kino a me ka pelvic nā loko.

Kāna hana o ka pā lonoaʻili a me Hawaii hana o kekahi mau wahi o ke kino ke hōʻike i ka hapa o ka spinalʻaha, a hiki i poino.

Maʻike ākea nā aʻalolo mai ka spinalʻula i ke aʻalolo impulses loaa nā loko o ke kino. Ka mea hooponopono i ka hana ana i nā mea a pau nā loko. Sensory nā aʻalolo olona, ke hoʻouna i 'ike mai nā'aʻaʻa a me nā loko i ka spinal kaula a me CNS.
