Lolu hlelo luqukethe iziqu ezimbili ezinkulu noma izintambo ze-ganglia (izikhungo zezinzwa), ezisuka kwisisekelo sobuchopho ziye ku-coccyx, futhi zitholakala ngokwengxenye kwesokudla nezinhlangothi zesobunxele nangengxenye engaphambili kwekholomu yomgogodla; futhi, futhi, kwezintathu ezinkulu ze-nerve plexuses nama-ganglia amaningi amancane emithanjeni yomzimba; nemicu eminingi yezinzwa evela kulezi zinhlaka. Izintambo zombili ziguqukela phezulu eqenjini elincane lobuchopho, futhi ngaphansi kweqembu le-coccygeal ganglion phambi kwe-coccyx.

Ku-Fig. VI-B, ngakwesobunxele lekholomu yomgogodla, kukhonjiswa enye yezintambo ezimbili zohlelo lwezinzwa oluhleliwe. Ukusuka kulo kubonakale kunwebeka ukwanda okubanzi kwemicu yezinzwa, ifomu ama-plexuse asakazeka njengesigcawu se-webs phezu kokugaya kanye nezinye izitho ezisezandleni zomzimba; kuma-solxus we-solar ahlanganiswa yi-vagus nerve yohlelo lokuzithandela.

I-Fig. VI-C iyisikebhe esibonisa izintambo ezimbili ze-ganglionic zohlelo lokuzenzela, eziguqula ngezansi; kwehla phakathi kwabo kukhona intambo yomgogodla, eqeda eduze ne-coccyx. Ezinhlangothini kukhonjiswa izinso, ezidlulela phambili yi-adrenals.
