Ubume bokutshiza bombhobho wefeni ethe tyaba ngunxantathu xa ujongwa ngaphambili, kwaye uyafana nomgca othe tye xa ujongwa ecaleni. Xa ujongwa ngaphezulu, icandelo lokutshiza lombhobho wefeni ethe tyaba limxinwa kumacala omabini kwaye libanzi kancinci kumbindi womnquma.

Uphawu lombhobho wefeni ethe tyaba kukuba inokuvelisa amandla amakhulu empembelelo. Kungenxa yokuba akukho malungu enza ukuba ulwelo lujikeleze ngaphakathi. Ngokuchasene noko, kufuneka sizame konke okusemandleni ethu ukuthintela ulwelo ukuba lujikeleze ngaphakathi kwalo. Uqhushululu luya kwenza umphumo wejet. Yithobe ngelixa unciphisa ifuthe layo. Kodwa ngenxa yendawo yayo encinci yokugubungela, efana nelayini ethe nkqo, ilungele ukufakwa kwibhanti yokuhambisa. Xa into eza kucocwa ishukuma ngokuhambelana nomlomo, iya kususa ngokulula izinto ezinamathelisiweyo kumphezulu wento leyo.

Njengoko kunokubonwa emfanekisweni, umlomo wombhobho wefeni othe tyaba wenziwe ngeesangqa ezimbini. Ezi semicircles zimbini ziya kufinya ulwelo ukufezekisa imilo yesitshizi fan fan. Ukuba ufuna ukufumana ulwazi oluthe kratya malunga nemilomo yefeni ethe tyaba okanye ufumane ikowuteshini engabizi kakhulu, ke nceda ukhululeke ukunxibelelana nathi.
