Ukuphakamisa ukuthi umlomo kungaba yibhethri nokuthi amazinyo angaba ugesi mhlawumbe kuzwakala ngokuxakile ngokusobala cishe kunoma ngubani ongafundile i-galvanism yomlomo. Kodwa-ke, iqiniso lokuthi isimo esinjalo singenzeka empeleni liyisisekelo.
Chofoza lapha ukuze ufunde i-athikili ephelele.
Ungabuka futhi le vidiyo ukuze ufunde kabanzi mayelana nokufakwa kwensimbi kanye ne-galvanism.
