Back uru. Anatomy nke musculature nke azụ.

The biomechanics nke ahụ mmadụ bụ nanị kwe omume ekele pụrụ iche mmewere nke otú dum dị ka a dum, ma na onye na usoro karịsịa. Muscular usoro n'oge ije na-arụ a na-eduga ọrụ. Ka ihe atụ, azụ uru.

Site elu elu spinal uru na-agụnye ndị na-esonụ iche nke uru ahụ:

- trapezius muscle, ma ọ bụ musculus trapezius, nke na-amalite site na ọkpụkpụ nke spinous Filiks nke thoracic vertebrae dum usoro. Ya mma - ije nke pupụtara na ndọtị isi.

- latissimus dorsi, nke enyene dum ya ala mpaghara. M. latissimus dorsi, na-emekarị na-amalite na ala nke 5 nke thoracic vertebrae, nakwa dị ka ihe niile nke lumbar na sacral vertebral spinous Filiks nke ala anọ na abụọ nke ọgịrịga na ma iliac crest. Function: The omission nke welitere aka na ubu adiana n'ime.

- rhomboid muscle. Ọ ụgha dị n'okpuru trapezius. Ndị ọrụ m. rhomboideus nekeko na agụba ije.

- levator scapulae muscle. Nke a muscle ebilite si Filiks ama cervical vertebrae, agwụcha na agụba, na ya elu nri akuku. M. levator scapulae, agwa ka aha ya, anamde eweli pupụtara.

- azụ ma na ala toothed muscle. Nke a muscle-akụ ọkpọ. Ọ bụrụ na ndị mbụ n'ime ha (nke pụtara na m. Serratus posterior elu) na-akpọlite ndị ọgịrịga, ikpeazụ (m. Serratus ihu usụhọde), na Kama nke ahụ, ha na-ala.
