Iqela leeseli kwizilwanyana ezinethambo lomqolo ezikhula kwintambo yemithambo-luvo
Impendulo echanekileyo iya kuba yiyo. isiko uvalo.
I-Vertebrates yenye ye-phyla ye-phylum Chordata kwizilwanyana. Iqela leeseli kwizilwanyana ezinethambo lomqolo eziphuhlayo kwintambo yemithambo-luvo ibizwa ngokuba yindlela yokusombulula. Ezi seli zikhula ecaleni kwentambo ye-nerve kwaye zidlala indima ebalulekileyo ekunikezeni uzinzo kunye nesakhiwo kwinkqubo ye-nervous. Indlela yesisombululo iyimfuneko ekuphuhlisweni okunempilo kwama-vertebrates kunye nokuxhasa ukusebenza okuqhelekileyo kwenkqubo ye-nervous. Ngaphezu koko, indlela yesisombululo inokunceda ekuboneni ukungahambi kakuhle kwinkqubo ye-nervous ye-vertebrates, evumela ukufunyanwa kwangaphambili kunye nonyango.
