Le nkqubo iqulathe iziqu ezibini eziphambili okanye iintambo ze-ganglia (amaziko emithambo yoluvo), ukusukela kwisiseko sobuchopho ukuya kwi-coccyx, kwaye ikumahlulo ngokwendlela kunene kunye namacala asekhohlo kwaye ngokuyinxalenye phambi komqolo; kwaye, ngokubhekele phaya, kwezinto ezintathu ezikhulu ze-nerve plexuses kunye neqela elincinci le-ganglia kwimizimba yomzimba; kunye neentsinga zemithambo-luvo ezininzi ezivela kolu lwakhiwo. Ezi ntambo zimbini ziyaguquka ngaphezulu kwiqela elincinci lobuchopho, kwaye ngezantsi kwiqela le-coccygeal ganglion phambi kwe-coccyx.

Kwi-Fig. VI-B, ngasekhohlo kwekholam yomgogodla, kubonakaliswa enye yeentambo ezimbini zenkqubo ye-nervous ozimele. Ukusuka kuyo kubonwa njengokwandiswa kwe-ramication ebanzi yeefayile ze-nerve, ezo imo I-plexuses ethe yasasazeka njengesigcawu sokutsala ngaphezulu kokugaya kunye namanye amalungu kwimizimba yomzimba; kwi-solxus ye-solar badibene ne-vagus nerve yenkqubo yokuzithandela.

Umzobo. VI-C ngumzobo obonisa izintambo ezimbini zenkqubo yemigulukudu, eguqula apha ngezantsi; ukuhla phakathi kwabo kukho intambo yomgogodla, eqeda kufutshane necoccyx. Kumacala aboniswe izintso, zongezwe zii-adrenals.
