Spinal akwara

Ọkpụkpụ azụ irighiri akwara na-metamernoraspolozhennye, paired akwara Kporo. The ọnụ ọgụgụ nke spinal akwara, ma ọ bụ kama, ha na abụọ kwekọrọ na nọmba nke abụọ nke agba nke ọgidigi azụ na hà iri atọ na otu: asatọ na abụọ nke cervical akwara, iri na abụọ na abụọ nke thoracic, ise lumbar, ise agha ntụte na otu ụzọ nke coccygeal irighiri akwara. Na enyemaka ha, ọgidigi azụ eneme ala na-eme akara toso, pelvis, aka na ụkwụ na esịtidem akụkụ nke abdominal na thoracic cavities.

Ya si spinal irighiri akwara jikọtara a kpọmkwem akụkụ nke ahụ ahụ, ya bụ innervated si na ụfọdụ ebe nke anụ somite - ewepụtara dermatosis nke myotome - uru nke sclerotome - ọkpụkpụ. Kwa akwara, si n'aka si "nke onwe" nke intervertebral foramen, na ejikọta a kpụrụ si onye nke n'ihu ogwe (moto) ma n'azụ (mwute) mgbọrọgwụ.

Ọkpụkpụ azụ akwara iru a ogologo nanị ọkara a sentimita, mgbe nile na ha n'alaka ụlọ ọrụ ahụ n'otu ụzọ ahụ n'azụ na n'ihu shei alaka.
