Anatomy yemuromo wenyoka

Kuti unzwisise kuti sei nyoka dzisingatsenga, zvakakosha kuongorora maitiro avo. Muromo wenyoka wakagadzirirwa kumedza mhuka huru. Rushaya rwepazasi rwenyoka rwakanyatsobatanidzwa nedehenya rayo, zvichiita kuti itambanuke yakashama kuti igare mhuka yakakura kudarika musoro wayo. Uyezve, muromo wenyoka une mazino akapinza anonongedza kumashure, ayo anobatsira kubata uye kubatirira pane inenge yabatwa. Magadzirirwo aya anoita kuti zvive nyore kuti nyoka imedze chikafu chayo isina kutsenga.

Mamiriro Akasiyana Emazino Enyoka

Kusiyana nedzimwe mhuka, nyoka dzine mazino asina kugadzirirwa kutsenga. Nyoka dzine marudzi maviri emazino: mazino uye mazino ekumashure. Mazino mazino marefu ane mhango anoshandiswa kubaya huturu mumhuka. Mazino ekumashure madiki uye anoshandiswa kubata nekubata mhuka. Hapana mhando yemazino akagadzirirwa kukuya kana kutsenga chikafu.
