Hloov pauv ntawm cov khoom siv raw cov khoom siv tau muaj cov hauv qab no ntawm kev lag luam ether cov khoom siv, (1) Cellule Kev Lag Luam, khoom ntau yam cuam tshuam rau lawv ntau lawm. dhau ntawm cov nyhuv. Feem ntau hais lus, kev lag luam nrog cov khoom lag luam siab, thiab cov khoom lag luam muaj txiaj ntsig zoo muaj cov peev txheej muaj zog, thiab cov tuam txhab yuav tswj hwm cov nyiaj tau los ntawm cov nyiaj tau los tau yooj yim; Cov tuam txhab uas muaj cov khoom lag luam uas muaj cov khoom lag luam muaj txiaj ntsig zoo, thiab cov khoom lag luam uas tsis muaj peev xwm hloov tau muaj peev xwm hloov pauv tsis muaj zog, tus nqi them tus nqi ntawm cov lag luam yog qhov siab. (2) Hauv ib puag ncig uas cov khoom lag luam tus nqi hloov pauv tau ntau dua thiab muaj txiaj ntsig zoo dua ntawm cov khoom lag luam me me ntawm cov khoom lag luam me me.
